Activity 2: Gravity (SI GLEs: 1, 2, 3, 4, 5, 6, 10, 11, 12, 13, 19, 20, 21, 22, 23, 25, 27, 28, 34; PS GLEs: 5, 7)
CC: Each group's experimental design should include a chart on which to record the results of each test performed. Have the students write clear, step-by-step instructions that others can follow to carry out procedures or conduct investigations.

Use a word processing program such as MS Word or Excel to design a chart. Space should be provided at the bottom for step-by-step instructions. Sample Chart: http://www.libraryvideo.com/ssl/data_sheets/K7108.pdf
CC: Divide the class into groups to research, discuss, and answer the following questions. Each group should prepare a presentation for the class. Use data to find the gravitational forces of the selected planets compared to Earth, and recalculate Olympic records in weightlifting, track and field, etc. for the chosen planet (use metric measure). Describe the performance of Olympic athletes on these planets. Use MS Word to generate a list or chart for data found. Word template for Planet Comparisons of Olympic Records
Describe the gravity experiments conducted by Galileo, Newton, and Cavendish. How were these experiments similar? How did these scientists build on each other's research and observations to make their discoveries?
