Earth's Place in the Universe 1a,b,d,e,g 2a,b,c,d,f,g
Make sure students illustrate their answers. I used this web site and various others to share illustration ideas with the class.
Text of Learning Exercise:
Three a day questions for earth systems science - encourage the use of illustrations and various mental models.
Compare: a. light years and astronomical units b. Mass and weight c. luminosity and albedo
How would earths albedo change if we cut down all the forests? What would it be like to lift rocks on the moon? What would it be like to run into rocks on the moon?
Compare solar systems and galaxies. Compare kinds of galaxies. Explain what might cause galaxies to differ.
What is the currently accepted explanation for the formation of the universe? What evidence is used to support this theory? Compare the formation of the Universe with the formation of the solar system.
Compare the sun to other stars. Compare the sun to a planet. Compare the sun to a moon.
Draw a picture of the sun and explain what you see: Color Sunspots Chromosphere as visible during an eclipse
Draw a picture of the sun and explain what you see: Prominences Solar flares Solar energy
Compare how energy moves through the sun and from the sun to the earth. What would happen if solar energy output was variable? How variable are the living things on planet Earth?
w variable are the planets in the solar system? Evaluate the possibility of life on other planets. What evidence is there that solar energy does vary over time?
What are pictures? How are they made? What are photographs? How are they made? Are all photographs the same? Explain.
Compare the kinds of images we get when using different parts of the electromagnetic spectrum. Explain why different stars produce different wavelengths. What have we not seen in space?
Compare specific features you can see on the Earth and on other solar system planets. Compare days on earth, moon, and any other solar system planet. Compare years on earth, moon, and any other solar system planet.
Compare the density of the interior and exterior planets. What does this density difference suggest about the composition of the two different groups of planets? What would density differences between the rocky planets suggest?
Compare the light produced by the sun and a fluorescent light bulb. Compare the light produced by the sun and a led. Explain the differences you are able to observe.
