Introduction: Have you ever shot a rubberband? Hopefully not at someone or in school. But what exactly made that rubberband fly? What makes that ball bounce, or an airplane defy gravity? The answers to these questions lie within the laws that govern forces and motion. Energy can be applied to stretching a rubberband or producing machines that can fly. In this activity you can learn about these principles and about what is often described as "the nature of things".

Activity 1: Meet with your team members and visit one of the websites below. Select two activities and printout the overviews and procedures. Make a list of the materials that you will need and obtain them. Practice the experiment until you can perform it efficiently. Be prepared to explain the scientific principles you have learned in your experiment to your classmates.

Activity 2 Using the information below create a spreadsheet that shows a person's weight on the moon, Mars, Jupiter and Pluto based on a given weight on earth.

Earth Weight	On The Moon	Mars	Jupiter	Pluto
Gravity=1	Gravity=.17	Gravity=.38	Gravity=2.38	Gravity=.07
100 lbs
150lbs
225 lbs
