Water Bottle Rocketry

We started the school year in Principles of Technology with a bang – more like a blast!

The first project, right out of the gates, was soda-bottle water rockets. This was the introductory project for the course and for Unit 1 – Motion.

The class was broken into self-selected teams of 1 to 3. The class was given a complete 2-liter soda bottle and access to random materials from around the classroom. The teams were given 3 90-minute class sessions to brainstorm and complete their rocket designs.

Upon completion of the designs and following the launches, teams completed force diagrams and a post-launch analysis explaining why their rockets performed the way they did.

Here are the various rockets on the morning of the launches…
