Rocket Science

There are many scientific reasons that bottle rockets can be studied, but perhaps the most important is that rockets are scientifically proven to make fun and exciting projects, especially if they make a huge mess.

5...4...3...2 Liter Blast Off

Objectives/Goals

The purpose of this project is to determine what water amount in a two-liter bottle rocket will make the rocket go to the highest altitude.

Methods/Materials

Bottle Rocket, Rocket launcher, Measuring Cup, Water, Angle finder,Tape measure, Back-up supplies

Results

In the launches, at 1250 ml. The rocket went the highest altitude. So, at about half water and not too much weight the rocket reached the highest altitude. At 62.5% of the rocket filled with water it reached the highest altitude.

Conclusions/Discussion

The results of the experiment were not as predicted. The rocket reached the highest altitude when it was filled with 62.5% of the total amount of water. This proves the hypothesis incorrect.

Summary Statement

Trying to see at what water level would a bottle rocket reach the highest altitude.
