Indirect+Measurement+Unit

//We may not go through them in exactly this order, but the objectives for this unit are that you will be able to do all of the following by the time we're done:// 1. Define indirect measurement. 2. Compare and contrast the models of the universe from Aristotle, Ptolemy, Copernicus, Galileo, Brahe & Kepler, and Newton. 3. Define a wave. 4. Explain the electromagnetic spectrum. 5. Explain how the composition of stars is determined. 6. Explain how it is determined that stars may be moving away or towards the Earth. 7. Describe Earth's position during summer and winter solstice and autumnal and vernal equinox. 8. Explain the formation of the sun and planets. 9. Be able to label and characterize the layers of the internal Earth. 10. Describe magnetism on and around the Earth, and how it affects the Earth.
