Centennial Jr. High
7th Grade Two-Liter Bottle Rocket Competition 2017
Description: Each student will design, construct and launch a rocket made from one or more 2L plastic soda bottles. The rocket will be launched at a 45o angle for maximum distance.
Research and construct rockets--May 18/19 and 22
Finish constructing and begin launching--May 23
Repair/remodel and lauch day--May 24
Final Launch--May 25/26
Data analysis and write-up--May 30
1. The body of the rocket must consist of one or more 2L pop bottles with attached fins, nose-cone, etc. No metal parts will be allowed on the rocket. (Fins cannot go below the lip on the neck of the bottle).
Rockets will be placed on a launcher and filled with approximately 85 psi of air. All energy imparted to the rocket must originate from the water/air pressure. No other energy source will be allowed.
2. Each rocket will be judged according to the distance it travels. The one traveling the longest distance will win the competition.
3. Students will launch the rocket using the launching pad provided by the adult supervisor. Students will measure their rocket’s distance, with the assistance of adult supervisor.
