# Lab 00-intro to island science

<span></span>

**Welcome!

This is a relatively new course, so we get to create as we go along.

First, here is our course description:

**Course Outline:

Only on our island can we explore all of these in one place:

- **Earth**<span style="font-size:13px;">: earthquakes, volcanoes, geothermal energy</span>
- **Ocean**<span style="font-size:13px;">: tsunamis, ocean energy, aquaculture, physical oceanography</span>
- **Atmosphere**<span style="font-size:13px;">: climate change, air quality, vog</span>
- **Stars**<span style="font-size:13px;">: astronomy, astrophysics, </span>**space weather,** <span style="font-size:13px;">Polynesian navigation</span>

This hands-on course will enable you to explore these with direct access to tools, sensors and experts on our island including Observatories on Mauna Kea, Mauna Loa, Hawaii Volcanoes and research at NELHA and the Pacific Tsunami Warning Center among others.

As a survey course, this is an excellent preparation for any college level science course in these fields beyond the scope of normal science courses.

Ok…

You may notice a theme of exploration. This is how we will approach island science, creating and using tools to explore.

Our goal therefore is to expand your curiosity and experience as an explorer.

**Class format/expectations:

We will meet about three times each week in the energy lab at the top of campus. You can walk across the troll bridge, or up the road from GPAC, up to you. We start class on time, and make sure to bring your charged laptop and phone to class.

We may be out in the field at times, and if we need to go far, like into the garden, I’ll try to give you warning so you wear appropriate attire.

We may also use a weblog to record your explorations, which will help you in creating future projects, but also help other students following in your explorations.

We may be using serious tools for our work-you are expected to treat these with respect, and don’t abuse the privilege of access. This also goes for internet and network use: if it violates the school acceptable use policy, you probably should think twice.

 If you find anything either in our discussions or in the material makes you uncomfortable, please reach out to me. My goal is to be inclusive and respectful of all viewpoints. This does not mean we’ll challenge accepted scientific principles like “did we really land on the moon” or “is climate change caused by human activity”.

**Grading**:

We’ll sort out the best way for you to record your progress as an explorer. I like the idea of logs, just like any other explorer, tracing your journey for others to follow. We can decide this as a group about this when we meet. Your participation and ability to record your journey are what is important. I’m a big fan of ownership: whatever you do here should be yours forever, not just until some huge exam.

**Energy Lab:** Please do not bring food or drink from outside into the energy lab. Students may bring in their own water containers, but since we have a limited supply of bottled water, please do not fill your containers from these bottles, instead use the water in the sinks, which is actually purified rainwater.

**Access**:

The best way to reach me is before or after class, but any questions about grading has to be taken care of outside of our class time, out of respect for others in the class as well as your privacy. My email is bill@hpa.edu, and I can answer your responses up until about 7 PM most evenings.

- circles are peaks
- many parallel lines is a flat slope
- V shapes are usually peaks
- no lines means a plain or flat surface
- steeper slopes have many line parallel, bunched together

# Lab 01c: navigation: celestial navigation overview

[https://en.wikipedia.org/wiki/Celestial\_navigation](https://en.wikipedia.org/wiki/Celestial_navigation)

Main points:

An astrolabe is a device for measuring altitude of objects, or the angles of stars or planets for navigation. You can make your own using a protractor, a straw, some tape, dental floss and a rock or weight (see below):

[http://www.hmdt.org.uk/STEM\_lesson\_plans/2%20Physics/2%20Hypatia/3%20Make%20an%20Astrolabe%20Worksheet.pdf](http://www.hmdt.org.uk/STEM_lesson_plans/2%20Physics/2%20Hypatia/3%20Make%20an%20Astrolabe%20Worksheet.pdf)

[https://www.nps.gov/teachers/classrooms/make-your-own-astrolabe.htm](https://www.nps.gov/teachers/classrooms/make-your-own-astrolabe.htm)

<span style="font-weight:bold;">Astrolabe for altitude:</span>

<span style="font-weight:bold;">45 degree method:</span>

- find your "eye height" by looking at a ruler on the wall, write this down
- set your astrolabe for 45°,
- walk towards the object (pole, building, tree) until it shows up in your sight
- measure the distance to the object
- add your eye height to this distance
- this is the height of the object (isosceles triangle)
- use this method to find the height of the elab, a flagpole, and several  objects of your choice

<div id="bkmrk-tangent-method%3A"><span style="font-weight:bold;">Tangent method:</span></div><div id="bkmrk-measure-a-distance-f">

- measure a distance from the object (huge tape measure can be useful here)
- measure the degrees you see in your astrolabe to the top of the object
- use the tangent calculator on your phone: tan = opposite (height)/adjacent (distance)
- you could also use: distance x tangent θ = height
- make sure to add your eye height
- use this method to determine the altitude of the same objects
- try to calculate the altitude of Mauna Kea by looking up the distance, knowing the elab is at 800 meters altitude (confirm this with the GPS on your phone)
- using google earth, look up the distance between several peaks on your map and make a scale ruler for your map
- use this scale ruler to find the distance to other peaks
- repeat the tangent method to find the height of each peak you can see: Hokuula, La'e La'e, Mauna loa...

<div>  
</div><span style="font-weight:bold;">Challenge: how could you use your astrolabe sideways to find your location?</span></div><div id="bkmrk-calculating-latitude">  
<div><span style="font-weight:bold;">Calculating latitude (latitude= "ladders")</span></div><div>First you have to understand the seasons...</div></div><div id="bkmrk-map-out-the-orbit-of">

- map out the orbit of the earth around the sun on your big piece of paper (we know it is not a circle, ok for now), using a loop of dental floss
- label out the seasons on your paper, including the tilt angle of the earth at each transition, March 21, June 21, September 21, December 21, with June 21 at the top of your paper
- at the equinoxes ("equal night") determine the tilt of the earth
- what would the angle of a shadow look like in Waimea at noon on this date?
- compare with Alaska, Spain, Brazil, Germany and a few others
- repeat this at the solstices for these locations-what do you notice?
- if we lived on the tropic of cancer (north) or tropic of capricorn (south) what would the sun angle be on the solstices?
- what about on the equinoxes?
- why are they named this way? (look this up)
- what would be the lowest angle the noon sun should be in Waimea, and on what date?
- what would be the highest angle the sun should be at noon in Waimea, and on what date?
- what are the longest and shortest days where you are from?

ok, now that we know the extremes, imagine we are in between one of these extremes:

- mark where we would be on your season map based on the date
- what degree should ours be between?
- measure the angle of the sun at around noon (noon is best, but close will be ok for now)
- using your angle, look up on a navigation almanac what our latitude should be
- how close are you?

<div><span style="font-weight:bold;">Calculating longitude ("long lines")</span></div></div><div id="bkmrk-first-we-have-to-und">First we have to understand a bit about astronomy, and why there is a famous telescope at a place called Greenwich near London...</div><div id="bkmrk-on-a-globe%2C-find-lon">

- on a globe, find London
- notice the longitude of London
- find the longitude of where you are from and record this
- if every 15° of latitude is one hour, calculate how many degrees away from London your home is exactly
- the telescope at Greenwich near London calculated noon exactly. If you had a clock with you, wherever you were on the planet, if you knew what time "local noon" was, you could calculate your latitude.
- there are a set of radio stations around the world that now broadcast this time signal on the radio, so ships and lost students can determine their latitude if they know local noon.
- on a radio, listen for WWV or WWVH (Hawaii version) on 10 MHz shortwave
- notice that when the chirps make a long beep, your phone, your computer and any device changes the minute-EXACTLY
- why do you care? if your computer or phone is on the wrong time even by a few minutes your web browser, email and everything on the internet will not work-why?
- Since our class does not meet at exactly noon, you can look up local noon on the web for this location
- calculate our longitude from this number
- since you can look on your super-fancy big island map, label our latitude and longitude if you have not already
- how many hours and minutes should we be from GMT (Greenwich Mean Time)?
- China has one time zone-how does this impact life there?

He sent a ransom video (by radio of course, so he could not be tracked) today at noon his time, dated 9.21

He had the radio on the background, which might give us a clue to his location, and there is a clear shadow behind him.

Here is the audio extracted from his ransom video, it might help us find Max:

# Lab 06c: navigation: find the evil villains!

International thieves have stolen a valuable artifact, and are demanding ransom, with their demands all arriving at noon today!

Your goal: using the shadow of the kidnappers (near the solstices of 9.21or 3.21) and any other information you can get from their ransom video-FIND THE THIEVES!

\----------------each of these videos arrived at the London headquarters of INTERPOL at noon (12:00 PM)

<span style="font-weight:bold;">Clues</span>:

1. From the angle of the shadow, calculate their latitude (at the equinox, this is their latitude, but be careful, this could be north or south)
2. From time clues in their videos, you can calculate their longitude (be careful: this could be east or west)

The Germans!

# Lab 05: navigation: tangents and mount Everest

<div id="bkmrk-tangent-method%3A"><span style="font-weight:bold;">Tangent method:</span></div><div id="bkmrk-measure-a-distance-f">

- measure a distance from the object (huge tape measure can be useful here)
- measure the degrees you see in your astrolabe to the top of the object
- use the tangent calculator on your phone: tan = opposite (height)/adjacent (distance)
- you could also use: distance x tangent θ = height
- make sure to add your eye height
- use this method to determine the altitude of the same objects
- try to calculate the altitude of Mauna Kea by looking up the distance, knowing the elab is at 800 meters altitude (confirm this with the GPS on your phone)
- using google earth, look up the distance between several peaks on your map and make a scale ruler for your map
- use this scale ruler to find the distance to other peaks
- repeat the tangent method to find the height of each peak you can see: Hokuula, La'e La'e, Mauna loa...

<div><span style="font-weight:bold;">Questions</span>:</div>

1. who measured the height of mount Everest?
2. how did he/she do it?
3. why do you need to know the elevation of your observation?
4. if you measure Mauna Loa as 5 degrees and it is 60 km away, what altitude above sea level is Mauna Loa?
5. Look up the true altitude and calculate your error

# Lab 04: navigation: astrolabe 45-90

<span style="font-weight:bold;">45 degree method:</span>

- find your "eye height" by looking at a ruler on the wall, write this down
- set your astrolabe for 45°,
- walk towards the object (pole, building, tree) until it shows up in your sight
- measure the distance to the object
- add your eye height to this distance
- this is the height of the object (isosceles triangle)
- use this method to find the height of the elab, a flagpole, and several  objects of your choice

# Lab 03: navigation: astrolabe

[https://en.wikipedia.org/wiki/Celestial\_navigation](https://en.wikipedia.org/wiki/Celestial_navigation)

Main points:

An astrolabe is a device for measuring altitude of objects, or the angles of stars or planets for navigation. You can make your own using a protractor, a straw, some tape, dental floss and a rock or weight (see below):

[http://www.hmdt.org.uk/STEM\_lesson\_plans/2%20Physics/2%20Hypatia/3%20Make%20an%20Astrolabe%20Worksheet.pdf](http://www.hmdt.org.uk/STEM_lesson_plans/2%20Physics/2%20Hypatia/3%20Make%20an%20Astrolabe%20Worksheet.pdf)

[https://www.nps.gov/teachers/classrooms/make-your-own-astrolabe.htm](https://www.nps.gov/teachers/classrooms/make-your-own-astrolabe.htm)

Goal: construct your own astrolabe

<span style="font-weight:bold;">Questions</span>:

1. why is it important to have the string go through the center hole and hang freely?
2. how accurate is your protractor in measuring degrees?
3. would your astrolabe be more accurate if the straw were replaced by a telescope? How?

- start with the equator: named because it is an equal distance from each pole
- notice there is a 0° mark on the equator
- track north to see the degrees marked-these are latitudes (think of rungs on a ladder)
- do the same going south
- notice the tropics of Cancer and Capricorn, these are named for the star constellations that are at these angles in the sky

<div>To navigate to a place on the globe, we need both latitude and longitude:</div><div><figure>![Screenshot 2026-02-03 at 2.33.04 PM.png](https://bookstack.kamuela.org/uploads/images/gallery/2026-09/5lnY8r6uN5UVY3kp-screenshot-2026-02-03-at-2-33-04-pm-ek22rj3d.png)<figcaption>Screenshot 2026-02-03 at 2.33.04 PM.png</figcaption></figure></div><div>

- Notice that 0° longitude is called the "prime meridian"
- This is no accident: the first telescope used to calibrate clocks to calculate longitudes while at sea was based outside London in a place called Greenwich (pronounced "gren-ich")
- This is why you might see times while traveling or calculating a phone or zoom call as GMT, this is Greenwich Mean Time, also known as UTC, or Coordinated Universal Time.
- In the diagram below, Washington DC is at 39° North Latitude or 39°N and 77° West Longitude (sometimes called 77°W

- map out the orbit of the earth around the sun on your big piece of paper (we know it is not a circle, ok for now), using a loop of dental floss
- label out the seasons on your paper, including the tilt angle of the earth at each transition, March 21, June 21, September 21, December 21, with June 21 at the top of your paper
- at the equinoxes ("equal night") determine the tilt of the earth everywhere on the planet
- what would the angle of a shadow look like in Waimea at noon on this date?
- compare with Alaska, Spain, Brazil, Germany and a few others that you pick
- Look these up here: [https://www.sunearthtools.com/dp/tools/pos\_sun.php?lang=pt](https://www.sunearthtools.com/dp/tools/pos_sun.php?lang=pt)
- repeat this at the solstices for these locations-what do you notice?
- if we lived on the tropic of cancer (north) or tropic of capricorn (south) what would the sun angle be on the solstices?
- what about on the equinoxes?
- why are they named this way? (look this up)
- what would be the lowest angle the noon sun should be in Waimea, and on what date?
- what would be the highest angle the sun should be at noon in Waimea, and on what date?
- what are the longest and shortest days where you are from?

Ok, now that we know the extremes, imagine we are in between one of these extremes:

- mark where we would be on your season map based on the date
- what degree should ours be between?
- measure the angle of the sun at around noon (noon is best, but close will be ok for now)
- using your angle, look up on a navigation almanac online what our latitude should be
- how close are you?

- the telescope at Greenwich near London calculated noon exactly. If you had a clock with you, wherever you were on the planet, if you knew what time "local noon" was, you could calculate your latitude.
- Local noon was found at sea by tracking the sun as it rose, and noting the time it was the highest, "local noon"
- Interestingly, dawn in Waimea is a bit earlier than dawn on Oahu, you can check this by talking to someone in the morning there, or even more fun, time our sunset with theirs-who will be later?
- there are a set of radio stations around the world that now broadcast this time signal on the radio, so ships and lost students can determine their latitude if they know local noon.
- on a radio, listen for WWV or WWVH (Hawaii version) on 10 MHz shortwave here: [https://wwv.mcodes.org/](https://wwv.mcodes.org/)
- notice that when the chirps make a long beep, your phone, your computer and any device changes the minute-EXACTLY

# Lab 09: earth: igneous rocks

Believe it or not, you are standing on igneous rock (unless you are standing on a coral head, which is illegal).

The Big island is one huge igneous rock, so pick up a piece and melt it with the sun.

MAKE SURE YOU USE THE DARTH VADER HELMET OR GREEN GLASSES

Your goal is to focus the sun's rays on a small spot using a large fresnel lens (like a normal lens in a camera, but made of grooves in a plastic sheet) and determine the melting point of igneous rocks on our island.

Cooking cookies with sunlight:

<figure id="bkmrk-img_1965.jpeg">![IMG&#95;1965.jpeg](https://bookstack.kamuela.org/uploads/images/gallery/2026-09/Oin9ZHEDtwZDvyzQ-513e4495-b7c0-44d5-b090-b2ebb455beb3.jpg)<figcaption>IMG\_1965.jpeg</figcaption></figure><span style="font-weight:bold;">Steps:</span>

1. find a darth vader welding helmet: some have fixed dark glass, others are "clear" until you see something bright like the sun.
2. test your helmet by looking at the sun-if it is a cloudy day, you might be able to ignite wood, but you will need a clear full-sun day to melt igneous rocks to magma
3. get the large plastic sheet that focuses sunlight-be careful handling it, and don't allow the focus to burn your feet or clothes
4. start by holding the lens perpendicular to the sun-you will need two people working together to make this possible
5. raise and lower the lens until you see a small bright dot on the ground
6. put a piece of wood where you see the dot, and try to ignite it, measuring the temperature with the scanning thermometer
7. repeat with burning the asphalt of the road (you will not be the first to do this), measure the temperature
8. repeat with an aluminum can, measure the temperature
9. If it is a full sun day, patiently aim at a piece of rock from around the elab-DO NOT use concrete or coral, concrete can explode if heated, coral is just nasty
10. continue until you can see the rock bubbling (it will turn red first) and measure the temperature
11. we have two types of cooled magma: a'a and pahoehoe-which did you create?
12. what is the difference between each of these, and why?

# Lab 11: earth: mapping earthquakes

Part 1: Shakenet

On your humongous map of the big island, we will be calculating the epicenter of earthquakes.

Here is an example of an earthquake measured by our seismic sensors (seismographs):

<figure id="bkmrk-quake.png">![quake.png](https://bookstack.kamuela.org/uploads/images/gallery/2026-09/ZzvThJE18EnPKi6G-quake-fskndo0x.png)<figcaption>quake.png</figcaption></figure>Terms:

- epicenter: the place on the surface above the quake
- hypocenter: the actual place under the surface where the quake occurred
- P wave: primary wave, a compression wave that travels fast, and can go through liquids (more on this soon)
- S wave: secondary (slower) wave, a transverse wave that cannot go through liquids
- Delay: for every second between P and S waves, you are 8 km from the quake
- You will also get to see a real-live quake sensor being built by Nick Winterowd from our ISR class

- On the right, you can select 24 hour view
- Look for a quake that happened recently
- Notice how spaced the front (P wave) and second part (S wave) are.
- Notice how far each station is from the red dot on the map that represents each quake.
- Calculate the distance from each station and draw a circle around it on your big big island map
- Determine the epicenter and hypocenter

# Lab 10: earth: volcanoes: magma, gases and spectra

[Simulator](https://elab.hpa.edu/isci/sims/volcano.html?target=)

Detecting the gas composition of a volcano is important in predicting impending eruption.

There are two types of magma, based on chemical composition:

- Basalt is runny, less-viscous magma that flows freely and creates the volcanoes we have in Hawaii
- Andesitic is sticky, more viscous and forms the cone shaped volcanoes in the Andes (hence the name), Japan, Indonesia, Mexico, and Italy.

<div id="bkmrk-magma-is-under-the-s">Magma is under the surface, Lava is once it reaches the surface, both are classed as igneous rock.</div><div id="bkmrk-https%3A%2F%2Fen.wikipedia">[https://en.wikipedia.org/wiki/Magma](https://en.wikipedia.org/wiki/Magma)

Teahupo’o

Even the wave’s name means “wall of broken skulls”. It is a hotspot for surfing competitions, known for its big waves and barrels but more than that it is known for its odd form. The reef wave breaks in an odd shape that gains attention—the crescent-shaped break forms this way as it breaks along a large crescent reef in Tahiti. The area breaks exceptionally at around 20ft and was the home of the 2024 Paris Olympic Games. The break season is from April to October and breaks well when the swell is in the southwest direction as waves sweep through the surrounding islands and condense the swell as it approaches the reef. The waveform is perfect at the high wave height due to the rapid gain in seafloor elevation up to the reef.

Banzai Pipeline

Banzai Pipeline or just Pipeline is the host of some of the biggest events in surfing. The wave is a go-to for competitive surfing during the winter months as the break offers as close to a perfect barrel as one could hope for. The wave breaks perfectly during the winter months and with a WNW or NW swell pattern. Again, the waves are known because of its ability to hold a perfect barrel even at large sizes. The wave hits the first reef at 15 feet from the surface causing it to shoot up where it leads into varying reef heights from 2-8 feet from the surface, making it extremely dangerous and creating the greatest barrel on earth.

Nazaré

Nazaré is one of the most bizarre breaks on the planet. The wave was first documented by foreign wave riders in the 1960s as locals told tourists from the United States of the North Beaches great waves in the winter season. The tourists were sadly only there during the summer and never were able to see these monster waves. It was not until the mid-2000s when a Portuguese bodysurfing local contacted famous American big wave surfer Garret McNamara who would go to fame because of his historic ride on this wave. Nazaré is unlike most other waves with it breaking on a sandbar, making it both unpredictable and typically not very horizontally long as it only breaks to the extent of the sandbar. Breaking on the North beach of Nazaré in Portugal the wave is home to the Nazaré Big Wave Challenge and holds the world record for the largest wave ever surfed at 93.97 feet. Another reason why the break is unique is as the winter season approaches and the WNW swell builds the swell travels through the canyon, allowing it to travel much faster as it approaches the shore. When it hits the canyon wall it shoots up and combines with the slow-moving swell on the side of the canyon to create the biggest wave ever surfed.

<div id="bkmrk-%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D">=====================================</div><div id="bkmrk-%F0%9F%8C%8A%E2%9C%A8-ocean-navigation-">🌊✨<span style="font-weight:bold;"> Ocean Navigation by the Stars — Using Star Walk</span>

🧭<span style="font-weight:bold;"> Lesson 1 — Finding Direction with the Sky</span>

<span style="font-weight:bold;">Objective: </span>Understand how stars move across the sky and how their patterns indicate direction.

<span style="font-weight:bold;">Key Concepts:</span>

 • Apparent motion of stars due to Earth’s rotation

 • Polaris (North Star) as a fixed directional marker

 • Southern Cross as a southern hemisphere guide

<span style="font-weight:bold;">Activity:</span>

 1. Open <span style="font-style:italic;">Star Walk</span> and set location to your local coordinates.

 2. Observe the sky through the app at sunset and identify <span style="font-weight:bold;">Polaris</span> (Northern Hemisphere) or <span style="font-weight:bold;">Crux</span> (Southern Hemisphere).

 3. Note how the stars rotate around these points using the app’s time-lapse function.

 4. Discuss:

</div>

> <div> • Why does Polaris stay still?
> 
> </div><div> • What does this tell sailors about latitude and direction?
> 
> </div><div> • How would you find north without a compass?
> 
> </div>

<div id="bkmrk-extension%3A-draw-your"><span style="font-weight:bold;">Extension:</span>

Draw your horizon and label east, west, and Polaris’ position relative to your latitude.

🌍<span style="font-weight:bold;"> Lesson 2 — Latitude from the Stars</span>

<span style="font-weight:bold;">Objective: </span>Measure and interpret star altitude to estimate latitude.

<span style="font-weight:bold;">Key Concepts:</span>

 • Altitude = angle above horizon

 • Polaris’ altitude ≈ observer’s latitude

 • Relationship between horizon, zenith, and celestial sphere

<span style="font-weight:bold;">Activity:</span>

 1. Use <span style="font-style:italic;">Star Walk</span> to locate <span style="font-weight:bold;">Polaris</span> and note its altitude on-screen.

 2. Compare to your known latitude (Star Walk provides this).

 3. Repeat at different simulated locations (change city in app).

 4. Record:

</div>

> <div> • “When Polaris is 0° high, I’m at the equator.”
> 
> </div><div> • “When Polaris is 90° high, I’m at the North Pole.”
> 
> </div>

<div id="bkmrk-5.-discuss-why-south"> 5. Discuss why southern hemisphere navigators use other stars instead.

<span style="font-weight:bold;">Extension:</span>

Students create a mini “sextant” using a straw, protractor, and string to measure altitude of Polaris outside.

🌊<span style="font-weight:bold;"> Lesson 3 — Wayfinding Like the Polynesians</span>

<span style="font-weight:bold;">Objective: </span>Explore how Pacific navigators used star lines and ocean cues.

<span style="font-weight:bold;">Key Concepts:</span>

 • Polynesian star compass

 • Star rising and setting points

 • Integration of ocean swells, wind, and birds in navigation

<span style="font-weight:bold;">Activity:</span>

 1. Use <span style="font-style:italic;">Star Walk</span> to locate <span style="font-weight:bold;">Orion</span>, <span style="font-weight:bold;">Sirius</span>, and <span style="font-weight:bold;">Pleiades</span>.

 2. Note the compass direction where each rises and sets.

 3. On a circular “star compass” diagram, label these as navigation points.

 4. Discuss:

</div>

> <div> • How could you sail east using star rise/set positions?
> 
> </div><div> • What if clouds obscure the stars — what other cues could you use?
> 
> </div>

<div id="bkmrk-extension%3A-watch-sho"><span style="font-weight:bold;">Extension:</span>

Watch short video or diagram of the <span style="font-weight:bold;">Polynesian star compass (Te Lapa)</span> and compare to your own diagram.

🌅<span style="font-weight:bold;"> Lesson 4 — Seasonal Shifts and Ocean Routes</span>

<span style="font-weight:bold;">Objective: </span>Understand how seasonal constellations guided long voyages.

<span style="font-weight:bold;">Key Concepts:</span>

 • Earth’s orbit and seasonal visibility of constellations

 • Relationship between star visibility and hemisphere position

 • Using changing skies to track time and season

<span style="font-weight:bold;">Activity:</span>

 1. In <span style="font-style:italic;">Star Walk</span>, advance the date month by month.

 2. Watch how constellations rise earlier or disappear.

 3. Identify which stars were visible during traditional Pacific voyages.

 4. Discuss how ancient navigators planned routes according to <span style="font-weight:bold;">seasonal star maps</span> and <span style="font-weight:bold;">trade winds</span>.

<span style="font-weight:bold;">Extension:</span>

Students write a short reflection:

“If I were sailing from Hawaiʻi to Tahiti, what star paths would I follow, and how would I know when to turn?”

🌌<span style="font-weight:bold;"> Lesson 5 — Modern and Ancient Navigation</span>

<span style="font-weight:bold;">Objective: </span>Compare celestial navigation to GPS and modern instruments.

<span style="font-weight:bold;">Key Concepts:</span>

 • Transition from celestial navigation → radio → satellite

 • How both rely on precise timing and position

 • Cultural importance of preserving wayfinding knowledge

<span style="font-weight:bold;">Activity:</span>

 1. Use <span style="font-style:italic;">Star Walk</span> to simulate positions of key stars during an ocean crossing.

 2. Compare how ancient navigators used angular measurements vs. how GPS triangulates satellite signals.

 3. Discussion prompts:

 • What knowledge is lost if we stop looking at the sky?

 • How could modern tools and ancient techniques complement each other?

<span style="font-weight:bold;">Extension:</span>

Have students design a <span style="font-weight:bold;">hybrid “digital star compass”</span> — combining AR sky data and real compass direction — and describe how it could help sailors or hikers offline.

🧩<span style="font-weight:bold;"> Assessments possible:</span>

 • <span style="font-weight:bold;">Creative Project:</span> Students create a <span style="font-style:italic;">star navigation logbook</span> tracing a fictional voyage using <span style="font-style:italic;">Star Walk</span> screenshots and reflections.

 • <span style="font-weight:bold;">Performance Task:</span> In pairs, students “sail” across the virtual Pacific, using only star rise/set directions in the app to explain their route.

 • <span style="font-weight:bold;">Reflection Essay:</span>

<span style="font-style:italic;">“What can celestial navigation teach us about observation, patience, and interconnectedness between Earth and sky?”</span>

  
</div><div id="bkmrk-%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D%3D-1">=========================version 1.0========================</div><div id="bkmrk-projects%3A"><span style="font-weight:bold;">Projects:</span></div><div id="bkmrk-1.-storytelling%C2%A0-%E2%80%A2-b"><span style="font-weight:bold;">1. Storytelling </span>

 • Begin with a short story of a Polynesian voyage (e.g., the Hōkūleʻa canoe’s modern voyages or ancient wayfinders sailing thousands of miles without instruments). See videos above

 • Look up pictures of Polynesian double-hulled canoes.

 • Ask: <span style="font-style:italic;">“How could they cross the ocean without GPS, compasses, or maps?”</span>

<span style="font-weight:bold;">2. Concepts of Polynesian Navigation</span>

 • <span style="font-weight:bold;">Stars as compass points</span>: Rising and setting stars mark east and west.

 • <span style="font-weight:bold;">Star lines</span>: Navigators memorized ~200 stars and their rising/setting positions.

 • <span style="font-weight:bold;">Dead reckoning</span>: Estimating speed/direction over time.

 • <span style="font-weight:bold;">Environmental cues</span>: Ocean swells, clouds, bird flight patterns.

 • Use a globe or map to show how far voyages reached (Hawai‘i, Tahiti, Aotearoa).

<span style="font-weight:bold;">3. Star Simulator Exploration </span>

 • Open the iPad star simulator (e.g., <span style="font-style:italic;">SkySafari</span>, <span style="font-style:italic;">Star Walk</span>, or <span style="font-style:italic;">Stellarium</span>).

 • <span style="font-weight:bold;">Find Polaris vs. Southern Cross</span>: Compare northern vs. southern navigation.

 • <span style="font-weight:bold;">Identify a star line</span>: Pick a canoe course (say east) and have students mark which stars rise/set at that bearing.

 • <span style="font-weight:bold;">Simulate voyaging at sea</span>: Dim lights, have students “steer” by keeping their iPad pointed at a chosen guiding star.

 • <span style="font-weight:bold;">Star compass activity</span>: Assign groups a quadrant (north, east, south, west). Each group records which stars rise/set in their direction and shares back to create a full class “star compass.”

<span style="font-weight:bold;">4. Hands-On Simulation (Optional Extension, 15 min)</span>

 • In pairs, one student is the “navigator” holding the iPad, the other is the “crew.”

 • The navigator gives directions based on a guiding star (“Keep the canoe under Orion’s belt, rising in the east”).

 • Rotate roles.

<span style="font-weight:bold;">5. Wrap-Up &amp; Reflection (10 min)</span>

 • Discuss: <span style="font-style:italic;">“What would be hardest about navigating this way?”</span>

 • Connect to science: role of Earth’s rotation, star paths, and latitude in navigation.

 • Reflection prompt: <span style="font-style:italic;">“If GPS stopped working tomorrow, what knowledge from Polynesian navigation would still help us?”</span>

# Lab 12: earth: biome hunt

[Biomes](https://en.wikipedia.org/wiki/Biome) are a way of describing an environment based on rainfall, temperature and altitude, along with proximity to the ocean in our island case. In the diagram below, temperature is on the X axis, while rainfall is on the Y axis in mm of rain per year:

# Lab 07: Earth, moon, sun and stars

<span style="font-weight:bold;">Everything rotates</span>

- When you look at a sunrise, is this to the east or west?
- Sunset? east or west?

<div id="bkmrk-it-turns-out-that-ev">It turns out that everything in our galaxy rotates in the same direction. If you use North on our globe as "up" and you look down on our planet, it rotates counter-clockwise, every 24 hours.</div><div id="bkmrk-we-rotate-in-the-sam">

- We rotate in the same direction around the sun every 365 days.
- The moon rotates around earth about every 28 days.
- The moon rotates itself in the same period, so the same "light" side is always facing us
- Every planet in our solar system rotates in the same direction around the sun (except Uranus, as it was hit long ago)
- Even the sun rotates in the same direction
- If you want a satellite to look down on the same place on earth, it has to rotate in the same direction every 24 hours too.

<span style="font-weight:bold;">Try this to visualize the moon phases:</span></div><div id="bkmrk-stand-with-your-back">

1. stand with your back to the north
2. put your left hand out-this should face east, the sunrise
3. put your right hand out-this should face west, the sunset
4. at sunset:
    1. a first quarter moon will be right overhead
    2. a full moon will be east, where your left hand points (second quarter)
    3. a third quarter moon will be straight down, below your feet
5. at sunrise:
    1. a full moon will be setting to the west (best one to remember)
    2. a third quarter moon will be overhead
    3. a first quarter moon will be straight down, below your feet

<div><span style="font-weight:bold;">Part 2: Earth tilt and shadows</span></div></div><div id="bkmrk-stand-with-your-back-1">

1. stand with your back to the north
2. put your left hand out, this should be east, the sunrise direction
3. put your right hand out, this should be west, the sunset direction
4. at noon the sun should be straight overhead
5. from our work on latitude, your shadow will be on your north side for most of the year
6. on the globe, find Hawai'i and the tropic of cancer-are we above it or below?
7. on the shortest day of the year, December 21, your shadow should be short and to the north
8. on the equinoxes (March 21 and September 21) your shadow will be north of you and about 21° from vertical (our latitude above the equator)
9. since we are between the tropics and the equator, on the longest days of the year, our shadow will actually be SOUTH of us-why?

<div><span style="font-weight:bold;">Part 3: Earth tilt and seasons</span></div></div><div id="bkmrk-many-folks-think-tha">Many folks think that our seasons are based on our distance from the sun, but it is actually the tilt (from above) that makes summer and winter, look at this:  
</div><div id="bkmrk-screenshot-2026-02-0-1"><figure>![Screenshot 2026-02-04 at 9.20.35 AM.png](https://bookstack.kamuela.org/uploads/images/gallery/2026-09/bYaKUtpML4cEKays-screenshot-2026-02-04-at-9-20-35-am-akixxnek.png)<figcaption>Screenshot 2026-02-04 at 9.20.35 AM.png</figcaption></figure>  

- This diagram can be confusing: the earth is always tilted at an angle of 22.5 degrees, but as it orbits the sun, this angle is away (winter for us), towards (summer for us) or perpendicular to the sun (equinoxes), so look below:

<div><figure>![Screenshot 2026-02-04 at 9.27.02 AM.png](https://bookstack.kamuela.org/uploads/images/gallery/2026-09/MTaCY7RQHzjTD6By-screenshot-2026-02-04-at-9-27-02-am-7cjroc3l.png)<figcaption>Screenshot 2026-02-04 at 9.27.02 AM.png</figcaption></figure></div>

- From your work on latitudes, notice how at noon on the equinoxes the sun hits every part of the planet at the angle of latitude, e.g. 0 degrees from vertical at the equator, and 90° from vertical at the poles
- Equinox means "equal night" so every part of the planet has a 12 hour day and 12 hour night.
- In Hawai'i our days do get shorter in the winter and longer in the summer, but because we are closer to the equator, this change in angle is not as great as it is near the poles, away from the equator.

<div><span style="font-weight:bold;">Part 4: Earth and constellations</span></div></div><div id="bkmrk-ancient-folks-used-t">

- <span style="font-size:13px;">Ancient folks used the stars to navigate, most importantly the Arabs traveling on the desert, and the Polynesians traveling on the ocean, since in both cases there are no mountains, rivers or other features to navigate by.</span>
- <span style="font-size:13px;">Arabs used the winds to some extent and the Polynesians used the winds and the waves to navigate as well as the stars.</span>
- <span style="font-size:13px;">Have a look </span>[here](https://spaceplace.nasa.gov/constellations/en/)<span style="font-size:13px;"> and check out this diagram:</span>

# Lab 14: earth: island water

In the Hawaiian language, we have two concepts of water:

- "wai" means freshwater, usually from rain, running in streams or rivers
- "kai" means saltwater, usually in the ocean or pools

<div id="bkmrk-there-are-exceptions">There are exceptions to this:</div><div id="bkmrk-as-you-know-we-are-t">As you know we are the Ka Makani, or "the wind", as "ka" is the definite article in Hawaiian, and "makani" means wind.</div><div id="bkmrk-our-rain-is-called-t">Our rain is called the "kipu'upu'u" or  needle rain as it comes in sideways, driven by the wind, and feeling like needles on the skin.</div><div id="bkmrk-rain-becomes-%22wai%22-w">Rain becomes "wai" which then runs into "kai".</div><div id="bkmrk-two-more-exeptions%3A">Two more exeptions:</div><div id="bkmrk-anchialine-ponds%3A-ne">

- anchialine ponds: near the shore fresh water runs under lava flows and forms ponds with a mixture of fresh and salty water
- water lenses: these are places near the shore where freshwater mixes with salty water, but not in a pond, like at Hapuna beach on the north side, or Kohala coast north of Kawaihae
- fun fact: when cattle were brought down to Kohala to be loaded onto boats, they would put their heads underwater to drink the cooler fresh water just under the ocean surface

<div><span style="font-weight:bold;">Your project:</span></div></div><div id="bkmrk-look-up-a-%22water-len">

1. look up a "water lens" and create an accurate cross sectional diagram on your big map of the water flow from rain falling on a basaltic volcano like ours and reaching the shore
2. research where these water lenses show up on the west shore, where you might go to the beach
3. research anchialine ponds on the same coast-why there?
4. map out the major streams around Waimea, and explain how diverting these has changed the coastal areas (look up these changes, from the 1950's). [https://www.youtube.com/watch?v=Gp3\_FXu5ULA](https://www.youtube.com/watch?v=Gp3_FXu5ULA)
5. look up the formation of the boat harbor at Spencer Beach (you can find old videos about this on youtube)
6. go back to your island map and map out the pelekane watershed
7. explain why hikers are not permitted in the watershed areas above our campus
8. explain why Waipio valley is so wet compared to the Kohala coast
9. look up orographic lifting and tie this into your answer above
10. explain why every southwest coast of every Hawaiian island is dry
11. explain why Kahoolawe is a desert island
12. look up the shape of the Koolau mountains on Oahu and explain why the northeast side is different from the southwest side
13. on your big island map, list the annual rainfall in each of the major town on the island
14. since we don't have any major rivers on our island, how does all of the rain reach the ocean?
15. what part of the water cycle reaches the reef and what is the impact?
16. who owns every well on the big island and why?

- At least 3 streams from mountains to sea
- At least 3 ahupua’a bounded by ridges with a stream in the middle
- A renewable energy source
- At least one active volcano
- At least 3 biomes

<span id="bkmrk-flora-and-fauna%3A" style="font-weight:bold;">Flora and fauna:</span>  

- Pigs.
- Chickens
- 1 animal of choice (NOT a unicorn)
- Each animal can be any known or unknown breed.

<span id="bkmrk-transportation%3A" style="font-weight:bold;">Transportation:</span>

- around the island (bike, ev, emoped?)

<span id="bkmrk-a-structure%3A" style="font-weight:bold;">A structure:</span>  

- House at least 2 people comfortably and safely.
- Sustainable: made of local materials
- Harvest your own energy (solar, tidal, geothermal-no nuclear or fossil fuels)
- Grow your own food for two people year round
- Harvest your own water for two people, year round
- Purify water (this can be filters, but no chlorine)

<div id="bkmrk-questions%3A-to-be-add"><span style="font-weight:bold;">Questions</span>: to be added as text boxes on your awesome poster of awesomeness:</div><div id="bkmrk-what-seasons-it-it-h">

- What seasons it it has and how do the seasons affect the island?
- Which angle the sun dial has to be at in order to work properly?
- How many hours from GMT. (East or west)?
- What is the weather on your island?
- How could I get there from a spot you choose on the planet (navigation)
- What stars could you see from there?
- What is the ocean like around your island (reefs, surfing, fishing)?
- Pick a spot on your island for an earthquake and pick another spot farther away and show the P and S waves in a sample diagram, including times
- If a person were lost on one part of your island, locate them using peaks (triangulation)
- Calculate the altitude of the tallest volcano or mountain using tangent
- Show at least one part of your island that is vulnerable to tsunamis, and another that is protected
- Draw a line on your island of the predicted sea level in 2100, when you are about 90 years old
