Water Bottle Rocket STEM Lab AERO02

Middle School Rocketry Physics Lab: 3-page STEM activity on Newton’s 3rd Law, water propellant ratios, apogee height math, & pressure thrust vectors.

Explore Newton’s Third Law of Motion, action-reaction forces, liquid reaction mass, pressure thrust, propellant ratios, and aerospace rocketry! The Water Bottle Rocket Thrust Mass STEM Lab (AERO02) challenges middle school student teams to act as propulsion test engineers, testing varying water propellant loads to maximize rocket apogee altitude.

Students explore rocketry mechanics, fuel mass ratios, force vectors, Newton’s laws, and height math calculations!
