In a rocket, fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber.

The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust.

To create our own rocket engines, we used straws and rocket figurines to blast off to Huntley Preschool!

The source of our engines? Our breath!

Utilizing their lungs, students blew into the straws which launched their rockets off of the ground!
