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 earth’s 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?


• Ho 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.
