    Intros-who, home?

    Email bill@hpa.edu

    1. where is home besides HPA?
    2. what are you most interested in?
    3. tell me something few people know about you


    Start at the wayfinding compass…

    1. note what you can see that is different, at different angles
    2. setup your phone as a compass, spyglass app is best for iOS
    3. take readings from at least 3 peaks (mauna)
    4. create your own big island map using the projectors in the classroom
    5. reverse your sightings to converge (hopefully) at our energy lab


    grading: on completion of tasks, demonstrate skills


    1. compass: 
      1. find true north on your phone, add spyglass app (iOS)
      2. sight peaks, or use headings, 180° inversion, triangulation to find elab, small island maps, sight from nav circle above elab, explain compass headings vs Hawaiian names on nav circle
      3. large island maps, replicate elab location from peaks (re-shoot with compass from nav circle), aim for better accuracy
      4. find locations from lists, large map
      5. I’m lost challenge: pick a spot, list headings to peaks, 1 minute cel without GPS
    2. astrolabe: 
      1. construct: protractor, straw, weight, floss
      2. 45-45-90 challenge
      3. tangent challenge
      4. find altitude of Mauna Kea
      5. 3d location: altitude of peaks, distance to peaks, triangulate
    3. earthquakes:
      1. on big map, locate seismic stations https://stationview.raspberryshake.org/#/?lat=20.02484&lon=204.32515&zoom=8.000
      2. map out recent quakes, choose one large one, note time and date
      3. go to each station and find same quake, measure P-S time, every second is 10.5 km
      4. triangulate to find epicenter (surface)
      5. if overlap, explain hypocenter vs. epicenter
    4. Astronomy
      1. use starwalk on iPads to simulate midnight, look for Polaris (north star, Hoku Pa’a)
      2. measure angle from horizon
      3. compare with our latitude
      4. change location on starwalk app to another part of the globe, look again for Polaris, compare with latitude
    5. Globe: seasons and inclination
      1. measure the shadow of a stick at noon at the elab, every day for a week
      2. compare with latitude measured on the globe for HPA
      3. email home or a friend far away, ask for a photo of a stick or chair at noon where they are, and the date of the photo
      4. as we near March 21, what happens to the angle? what does it approach?
      5. on a globe, imagine what the shadow angle will be for a list of locations around the globe, N and S hemispheres
      6. find me challenge: ransom note with time stamp and shadow-locate the kidnappers
      7. what is the connection between GMT, clocks and English spoken around the world?
    6. Geology
      1. using the huge magnifiers, and welding masks, melt some igneous rocks downstairs (don’t try with coral or concrete, they explode)
      2. using the high temp thermometer, find the temp of the magma
      3. look up the magma at Kilauea and compare
      4. why are there so many gases coming out of Kilauea, and how are they dissolved in the magma? compare to carbonated drinks.
      5. why are the vapor/gases from Kilauea harmful?
      6. how do we know what they are made of? (spectroscopes)
      7. could we use the same tools to find exoplanets?
      8. using purpleair.com, find the air quality around the state
      9. using elab.hpa.edu, look for the vog flume
    7. Biomes
      1. back to the big maps, map out the biomes on the big island
      2. map out the last major eruptions and lava flows, including speed
      3. compare the biomes on this island with those on the other islands
      4. on a small map of the island chain, map out the biomes
      5. using google earth, extend this to include the ocean floor-why does the line change?
      6. look up the Nu'uanu Slide and link this to the calving of basaltic volcanoes
      7. compare with andesitic volcanoes
    8. Weather
      1. track the weather on all islands in our chain
      2. look for major influences across the Pacific: H and L centers, how they rotate
      3. explain why the wind on Mauna Kea is often the reverse of surface wind
      4. why is Waimea so windy and rainy? Think of the mountains
      5. look on elab.hpa.edu for the weather today, using the windy app
      6. repeat using the tempest app
      7. go to weather.hawaii.edu to compare with these
      8. how do clouds form?
