This applet has been designed to help students visualize Kepler's
three laws.

Students will begin by viewing each of the three animations after
which, they will formulate their own explanation for the three laws
and will type those into the text fields provided. Once students
have completed all three laws, they can use the calculator provided
to test Kepler's third law with actual numbers from the Planets
Data Table or the Quick
Fact Data Sheets.

Students should use the print function to print a summary sheet
of Kepler's Laws with the explanations they inputted.
