Propulsion - Model Rockets - Episode 205



Foot Power
You can study the effect of increasing mass on the flight of a stomp rocket. Have one person be the "stomper" for each test. Use a stopwatch to measure the time from launch until landing, or have your teacher show you how to use an inclinometer to measure the height. Use pieces of clay to make the rocket a little bit heavier with each trial. See if it makes a difference where you put the clay (at the tip, or near the fins).
