Understand the layers and functions of the Sun. 12. Understand what an Astronomical Unit is. 13. Know the Astronomical Unit distances for each of the four inner planets. 14. Know characteristics such as period of revolution, period of rotation, atmospheric compositions and number of moons for the inner planets. 15. Understand and conclude that period of revolution is related to distance the planet is from the Sun. 16. Define , Discuss and Illustrate Solar and Lunar Eclipses including the Umbra and Penumbra. 17.

Make a connection between Revolution and length of year. 23. Make a connection that rotation equals length of day on a planet. 24. Understand that solar system distances between planets is measured in Au's (Astronomical Units.) 25. Understand that periods of revolution grow longer as the planet becomes further from the Sun. 26.
