Island Science - Migration Test Temporary test migration from Apple Server Wiki Lab 00-intro to island science 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: earthquakes, volcanoes, geothermal energy Ocean: tsunamis, ocean energy, aquaculture, physical oceanography Atmosphere: climate change, air quality, vog Stars: astronomy, astrophysics, space weather, Polynesian navigation 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. Migrated from Apple Server Wiki.

Finding yourself on the map: hold your pencil on the peak you have sighted calculate the degrees the peak would see you: if less than 180°, then add 180°, if more than 180, subtract 180. from the peak set your compass on the peak and rotate until the degrees from north (vertical lines on the map) align with your number draw a line backwards from that point where at least three lines intersect, this is where you are Finding a lost person:You are injured in the rain forest, and have only a little battery left on your phone. Your GPS is not working since the rain forest blocks the signal, but you can see three peaks, and you can call 911, but only briefly.Measure the compass heading to each peak, and tell the 911 folks where you are.Help should come soon!

Original page ID: x5e2H8S Lab 01c: navigation: celestial navigation overview 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 https://www.nps.gov/teachers/classrooms/make-your-own-astrolabe.htm Astrolabe for altitude: 45 degree method: 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 choiceTangent method: 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... Challenge: how could you use your astrolabe sideways to find your location? Calculating latitude (latitude= "ladders")First you have to understand the seasons... 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?Calculating longitude ("long lines")First we have to understand a bit about astronomy, and why there is a famous telescope at a place called Greenwich near London... 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?Putting it all together:You now know how to find your latitude using an astrolabe, and your longitude using an astrolabe and a good clockLook up how to do this with your hands if you are lost in the wilderness or at sea...

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: IMG_1965.jpeg Steps: find a darth vader welding helmet: some have fixed dark glass, others are "clear" until you see something bright like the sun. 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 get the large plastic sheet that focuses sunlight-be careful handling it, and don't allow the focus to burn your feet or clothes start by holding the lens perpendicular to the sun-you will need two people working together to make this possible raise and lower the lens until you see a small bright dot on the ground put a piece of wood where you see the dot, and try to ignite it, measuring the temperature with the scanning thermometer repeat with burning the asphalt of the road (you will not be the first to do this), measure the temperature  repeat with an aluminum can, measure the temperature  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 continue until you can see the rock bubbling (it will turn red first) and measure the temperature  we have two types of cooled magma: a'a and pahoehoe-which did you create? what is the difference between each of these, and why?

Here is an example of an earthquake measured by our seismic sensors (seismographs): quake.png 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 First, go here:https://stationview.raspberryshake.org/#/?lat=19.49605&lon=204.59525&zoom=9.706 Look at the stations, and pick one on our island 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 Questions:  why would the gap in Hilo be smaller than the one at HPA? look up why it is important to know that only P waves travel through liquids how did the seismic network on the planet show us what the core of the earth is made of? who constructed this network and why? what is the Richter scale, and how much stronger is a 5.0 than a 4.0 quake? below is a report on a quake in Japan.

Original page ID: m093f9K Lab 10: earth: volcanoes: magma, gases and spectra Simulator 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. Magma is under the surface, Lava is once it reaches the surface, both are classed as igneous rock.https://en.wikipedia.org/wiki/Magma Once magma reaches the surface, it becomes lava, and can then solidify into several forms:a'a is the Hawaiian name for rock that cools very quickly, while gases are still bubbling from the lavapahoehoe is the ropey rock that is formed when lave cools more slowlyobsidian is the glass like rock formed if the lave cools very slowly Pumice is a version of a'aPele's hair is magma that solidifies in the air, making strands of rockVog is small particles of pumice with sulfuric acid in the small spaces-very irritating  Part 1: Magma temperature Using the massive lenses we have in the lab below, and using the Darth Vader helmets or goggles for protection, focus the sunlight on any rock you find on this island (why not coral or concrete?) Using the infrared temp sensor, measure the temperature of the magmaPart 2: Volcanic gases Go to the purple air website and look up the air quality around our island (over 50 is bad) Investigate the different settings for types of volcanic gases  Go to weather.hawaii.edu and search for the vog cloud map When would our air quality be poor and why? Challenge: pick a place on the planet that has the worst air you can find: put the numbers on the board for the class to find themPart 3: Spectra of gasesUsing a spectroscope, look at several chemical vapors such as sodium, potassium and other flame test colorsThese indicate what element is present, and can be used to measure relative amounts Questions: how is gas composition related to the depth of the magma? what sort of rock would be formed from magma cooling underwater? why would andesitic volcanoes explode while basaltic ones do not? which type is vesuvius and what happened there? why do volcanologists concentrate so much on expelled gases? is it a practical or scientific reason?

Finally, focus on Hawaii, the island you live on today, see what clues there are for you What clues did you use in each case? Biome mapping: Biomes are defined by temperature and water, with some variations with altitude, which impacts both, as well as distance from the ocean (why?). Fortunately we live on an island with many of the defined biomes used to define ecosystems around the planet. Your challenges:  1 Biome map of Hawaii Island: Map out the biomes we have on our island on your huge big island map, with some detail about each (min-max temp, annual rainfall). at the bottom of your map, include your home location, with a description of the biome there (Brazil, Spain, Germany, Mars, etc.)2 Your kingdom mapAs the ruler of your own island, you know a great deal about it. On a large paper, sketch out what your home island looks like. It must include the following: at least one volcano at least three valleys next to each other, with ridges on each side and a stream running through the middle a coral reef where each river meets the ocean some form of vegetation: trees, vines, grass, etc. some form of animals for food (be creative, but no cannibals please) Joke: why don't cannibals eat clowns? They taste funny... a description of the weather and biome there three ahupua'a, one on each side of the main river 3 Questions: email your answers for credit what sort of animals (fauna) and plants (flora) would you expect to find in each biome on our island? biomes are like your friends: it is not so much what they will do, it is what they won't do-how are these similar? why is the big island able to host so many different biomes, and compare it to another place on the planet of similar size how does a marine environment impact the biomes? include a photo from google earth of your home location and what biome is there Migrated from Apple Server Wiki.

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.  Competition: Kelly Slater vs. John John Florence - Billabong Pro Tahiti 2016 Final Big Surf: Biggest, Scariest Teahupoo in Over a Decade 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. BEST WAVES IN YEARS (MASSIVE PIPELINE) Perfect Pipeline With Kai Lenny And The GOAT Kelly Slater! 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. 100ft World Record Wave, Garrett McNamara Surfing Nazare, Portugal Migrated from Apple Server Wiki.

Key Concepts: • Apparent motion of stars due to Earth’s rotation • Polaris (North Star) as a fixed directional marker • Southern Cross as a southern hemisphere guide Activity: 1. Open Star Walk and set location to your local coordinates. 2. Observe the sky through the app at sunset and identify Polaris (Northern Hemisphere) or Crux (Southern Hemisphere). 3. Note how the stars rotate around these points using the app’s time-lapse function. 4. Discuss: • Why does Polaris stay still? • What does this tell sailors about latitude and direction? • How would you find north without a compass? Extension: Draw your horizon and label east, west, and Polaris’ position relative to your latitude. 🌍 Lesson 2 — Latitude from the Stars Objective: Measure and interpret star altitude to estimate latitude. Key Concepts: • Altitude = angle above horizon • Polaris’ altitude ≈ observer’s latitude • Relationship between horizon, zenith, and celestial sphere Activity: 1. Use Star Walk to locate Polaris 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: • “When Polaris is 0° high, I’m at the equator.” • “When Polaris is 90° high, I’m at the North Pole.” 5. Discuss why southern hemisphere navigators use other stars instead. Extension: Students create a mini “sextant” using a straw, protractor, and string to measure altitude of Polaris outside. 🌊 Lesson 3 — Wayfinding Like the Polynesians Objective: Explore how Pacific navigators used star lines and ocean cues. Key Concepts: • Polynesian star compass • Star rising and setting points • Integration of ocean swells, wind, and birds in navigation Activity: 1. Use Star Walk to locate Orion, Sirius, and Pleiades. 2. Note the compass direction where each rises and sets. 3. On a circular “star compass” diagram, label these as navigation points. 4. Discuss: • How could you sail east using star rise/set positions? • What if clouds obscure the stars — what other cues could you use? Extension: Watch short video or diagram of the Polynesian star compass (Te Lapa) and compare to your own diagram. 🌅 Lesson 4 — Seasonal Shifts and Ocean Routes Objective: Understand how seasonal constellations guided long voyages. Key Concepts: • Earth’s orbit and seasonal visibility of constellations • Relationship between star visibility and hemisphere position • Using changing skies to track time and season Activity: 1. In Star Walk, 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 seasonal star maps and trade winds. Extension: 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?” 🌌 Lesson 5 — Modern and Ancient Navigation Objective: Compare celestial navigation to GPS and modern instruments. Key Concepts: • Transition from celestial navigation → radio → satellite • How both rely on precise timing and position • Cultural importance of preserving wayfinding knowledge Activity: 1. Use Star Walk 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? Extension: Have students design a hybrid “digital star compass” — combining AR sky data and real compass direction — and describe how it could help sailors or hikers offline. 🧩 Assessments possible: • Creative Project: Students create a star navigation logbook tracing a fictional voyage using Star Walk screenshots and reflections. • Performance Task: In pairs, students “sail” across the virtual Pacific, using only star rise/set directions in the app to explain their route. • Reflection Essay: “What can celestial navigation teach us about observation, patience, and interconnectedness between Earth and sky?” =========================version 1.0========================Projects: 1. Storytelling  • 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: “How could they cross the ocean without GPS, compasses, or maps?” 2. Concepts of Polynesian Navigation • Stars as compass points: Rising and setting stars mark east and west. • Star lines: Navigators memorized ~200 stars and their rising/setting positions. • Dead reckoning: Estimating speed/direction over time. • Environmental cues: Ocean swells, clouds, bird flight patterns. • Use a globe or map to show how far voyages reached (Hawai‘i, Tahiti, Aotearoa). 3. Star Simulator Exploration  • Open the iPad star simulator (e.g., SkySafari, Star Walk, or Stellarium). • Find Polaris vs. Southern Cross: Compare northern vs. southern navigation. • Identify a star line: Pick a canoe course (say east) and have students mark which stars rise/set at that bearing. • Simulate voyaging at sea: Dim lights, have students “steer” by keeping their iPad pointed at a chosen guiding star. • Star compass activity: 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.” 4. Hands-On Simulation (Optional Extension, 15 min) • 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. 5. Wrap-Up & Reflection (10 min) • Discuss: “What would be hardest about navigating this way?” • Connect to science: role of Earth’s rotation, star paths, and latitude in navigation. • Reflection prompt: “If GPS stopped working tomorrow, what knowledge from Polynesian navigation would still help us?” Migrated from Apple Server Wiki.

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. 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.

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. Part 4: Earth and constellations 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.

A full moon rises at sunset, what time will it be highest in the sky? What time will it set? A waxing crescent is visible in the western sky just after sunset, what phase comes next? On June 21, which hemisphere receives more direct sunlight? If you are at 23.5°N on the summer solstice, what does your shadow look like? A kayaker says:” the moon rose around midnight, it looked half illuminated, and the bright side was on the left” What phase is the moon? What time of month is it?

What phase do you see and where is the Sun? Quick Check If the Moon rises at sunset, what phase is it? Check Day of year ~172 = June solstice172 Earth axial tilt (degrees) Real Earth ≈ 23.5°23.5° Observer latitude -66.5° to +66.5°19.0° Season: — Day length: — Try this: Set latitude to +19° (Hawaiʻi). Drag the day-of-year across the year. Notice how day length changes only a little near the tropics. Quick Check What causes seasons (one phrase)? Check Your latitude (degrees) Polaris altitude ≈ latitude (N hemisphere)19° Polaris altitude: — Visible? — Rule: In the Northern Hemisphere, Polaris’s height above the horizon (in degrees) is about your latitude. Quick Check If Polaris is 25° above the horizon, your latitude is: Check Local clock time when the Sun is highest (local noon) This slider is GMT/UTC time at your local noon14.00 h Time difference: — Longitude: — Rule: 1 hour of time difference = 15° of longitude. If your local noon happens when GMT is later, you are west of Greenwich. Quick Check If local noon happens at 2 PM GMT, your longitude is: Check Works offline.

Original page ID: r160f4 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 poolsThere are exceptions to this:As you know we are the Ka Makani, or "the wind", as "ka" is the definite article in Hawaiian, and "makani" means wind.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.Rain becomes "wai" which then runs into "kai".Two more exeptions: 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 surfaceYour project: 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 research where these water lenses show up on the west shore, where you might go to the beach research anchialine ponds on the same coast-why there? 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 look up the formation of the boat harbor at Spencer Beach (you can find old videos about this on youtube) go back to your island map and map out the pelekane watershed explain why hikers are not permitted in the watershed areas above our campus explain why Waipio valley is so wet compared to the Kohala coast look up orographic lifting and tie this into your answer above explain why every southwest coast of every Hawaiian island is dry explain why Kahoolawe is a desert island look up the shape of the Koolau mountains on Oahu and explain why the northeast side is different from the southwest side on your big island map, list the annual rainfall in each of the major town on the island since we don't have any major rivers on our island, how does all of the rain reach the ocean? what part of the water cycle reaches the reef and what is the impact? who owns every well on the big island and why? Migrated from Apple Server Wiki. Original page ID: Y5L6c8 Lab Final: amazing mystery island Where is the island located? It can be in any sea on earth. It is an island, after all... Must include: Latitude and longitude  Island population between 2-1000 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 biomesFlora and fauna: Pigs. Chickens 1 animal of choice (NOT a unicorn) Each animal can be any known or unknown breed. Transportation: to and from the island (no spaceships or teleportation) around the island (bike, ev, emoped?) A structure: 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) Questions: to be added as text boxes on your awesome poster of awesomeness: 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 Migrated from Apple Server Wiki.
