Materials needed:

• 2-4 2 liter pop bottles
• cardboard, posterboard, plastic etc. for fins and cones
• some mass
• water
• launcher
• air pressure

Objectives: The students will:

• Experimentally infer Newton's three laws of motion
• analyze motion using Newton's three laws
• create a model rocket that incorporates all three laws which will produce a flight of at least 200' and land within a 25' radius of the launch site

Experimental data write-up:

IA. Create a hypothesis that relates Newton's first law - inertia, and the ability of your rocket to keep flying and cone assembly.

B. Create an experiment that will test your hypothesis using a prototype rocket. Remember you'll need to test for mass variables, therefore you'll do at least three experimental launches.

C. Create a data table below that records and helps you analyze your results.

D. Have the teacher check off each experimental launch.

E. According to your experiments, how will you engineer your rocket cone? Draw and explain below.

II A. Create a hypothesis that relates Newton's second law, to the force (air pressure) and amount of fluid in your rocket to achieve maximum height.

B. Create an experiment that will test your hypothesis using a prototype rocket. Remember you'll need to test for pressure and fluid type or amount variables, therefore you'll do at least three experimental launches.

C. Create a data table below that records and helps you analyze your results.

D. Have the teacher check off each experimental launch.

E. According to your experiments, how will you engineer your rocket's propulsion system? Draw and explain below.

III A. Create a hypothesis that relates Newton's third law, to the fins, cone length or other add-ons on your rocket to achieve the straightest takeoff and landing.

B. Create an experiment that will test your hypothesis using a prototype rocket. Remember you'll need to test for fin shape, strength, cone length, ect. variables, therefore you'll need to do at least experimental launches.

C. Create a data table below that records and helps you analyze your results.

D. Have the teacher check off each experimental launch.

E. According to your experiments, how will you engineer your rocket's stabilizing system? Draw and explain below.
