GEODESIC DOME / PLANETARIUM
Visit the "Planetarium Blog" at:
You will be involved in a project at Senior High where math and science classes will collaborate to build a geodesic dome. Upon completion, the geodesic dome will be used as a planetarium to discover the wonders of the universe in an immersive environment.
Follow the instructions of the webquest and answer the questions:
1. Define "geodesic"
2. Define "planetarium"
3. What is a geodesic dome?
4. Who designed the first geodesic dome? What year? What was it used for?
5. List two structural advantages of a dome.
6. List two disadvantages to building a geodesic dome for a home.
7. List 5 different uses for "mega-sized" geodesic domes by examining the 10 largest in the world
8. According to this website, which "office supplies" would be useful for attaching the different triangles of the geodesic dome together?
9. Using the site above, click on "Dome Calculator" to the left. Click on 3V. See if you can find the assembly diagram for a dome with a radius of 7.5 feet. How many pentagons (5 sided figures) will be needed for construction of this type of dome?
(Hint: Look for the assembly diagram. Think about the diagram in three dimensions because you can only see one side on the diagram.)
This is the website for the Taylor Planetarium at The Museum of the Rockies in Bozeman, MT. Check out the interactive game from the planetarium at:
10. Find Ursa Major by clicking on the various stars. Explain what Ursa Major is.
11. Find Hercules. Explain the constellation.
Print and build the geodesic dome.
