Embed code for: Stomp Rocket Lab
Select a size
Use the template on the last page to create a paper rocket that can be launched with PVC pipe and a 2-Liter bottle. Test it out. Make modifications and try again.
Stomp Rocket Lab Name: ___________________________________
Hypothesis: (Which modification do you think will result in a larger travel distance?) ____________________________________________________________________________________________________________________________________________________________________________________________________
2 or more 2-Liter bottles duct tape Optional Items: 12” x 24” construction paper
24” length of 1” garden tubing tape markers
24” length of rigid PVC pipe scissors ruler
Stomp rocket handout glue trundle/measuring wheel

Inclinometer (or inclinometer app)
1) Cut out and follow directions on the Stomp Rocket hand out to build your rocket.
2) Use duct tape to attach the 2-L bottle to one end of the plastic tubing, and the PVC pipe to the other end.
3) Place the rocket carefully on the open end of the PVC pipe, and place the 2-L bottle on the ground.
4) Have one partner hold the PVC pipe/rocket at an approximately 45-degree angle. Once in place, the other partner stomps on the 2-L bottle to launch the rocket.
5) Measure the horizontal distance between the launchsite and wherever the rocket first hits the ground. Record data.
6) Blow into the PVC pipe to re-inflate the 2-L bottle. Repeat Steps 3-5 two more times.
7) Calculate the average horizontal distance travelled and record data.
8) Redesign your rocket choosing ONLY ONE modification to make. (This should relate to your hypothesis.)
9) Repeat steps 3-7 and record all data.
Horizontal Launch: Standard Rocket
Distance travelled (in meters)
Horizontal Launch: Modified Rocket
What ONE modification did you make? ____________________________________________________
Average Distance travelled for Standard Rocket
Average Distance travelled for Modified Rocket
Was your hypothesis supported? What was your modification and did you find it effective on your rocket?
What modification did you find most effective out of all the modifications made in the class? Why do you think this may be true?
List at least 3 experimental errors that may have resulted in different distances achieved with the same rocket?
Given more time, what other modifications (non-powered) do you think might help?
How does this relate to Newton’s Third Law of Motion?
