Second grade aerospace engineers continued their study of forces during our rocket lab. We used three types of rockets to learn more about thrust and Newton’s Laws of Motion.

This balloon moved about twenty feet along the straw after I inflated it. Would the rocket move further if we used a longer balloon, fishing line, or taped the balloon onto the straw in a different place? Click here for more directions. Make one at home!

We moved outside to use a stomp rocket. We observed that there was a correlation between the amount of force that was applied and the distance to which the rocket flew. But pop rockets (film canister explosions) were the favorite. We used a solid and a liquid to create a gas. Click here for more information.

Best day ever!
