Today, students read an article in the Gravity Workbook, Chaos Among the Planets, pgs. 4-5. The article describes what may have happened in the early Solar System. A group of scientists proposes the outer planets were much closer to the Sun. Over time, because of gravitational influences, the planets moved through the Solar System to where they are located now. Students answered questions about the article on pgs. 5-6.
Next, students began working on Gravity Explorations, pgs. 6-12, Gravity Workbook. Students calculate how much a person would weigh, how far a person could jump, and how high a person could jump on other world. The purpose of this activity is to show how the mass of the planet affects the strength of its gravity.
In the afternoon, students continued working on the Space Exploration Timeline assignment.
