Lesson plan


Shoot off rockets powered by gas pressure, generated by various means.
Science content
Chemistry: States of Matter, Properties of Materials (K-7)

Choose two activities for a lesson.

Shoot off film canister rockets.
Discuss the chemistry and the gas pressure that builds up and sends it upwards.
Set off the more powerful baking soda and vinegar rocket as a demonstration, which uses the same mechanism.

Instead of making the gas pressure from a chemical reaction, a chamber can be compressed to increase gas pressure: air pressure rocket (very powerful - be careful) or stomp rocket.

Discover chemistry that makes real rockets fly.

Energy transformations in rockets.
Baking soda and vinegar/Alka seltzer rockets use chemical energy into motion energy.
