The high school physics class moved on from their Thermal Energy Unit after the semester to more Projectile Motion.

For the lab to begin their unit, students made four different sized paper helicopters to drop from the ceiling. Each student climbed up the ladder, and dropped their helicopters one at a time.

The rest of the class was in charge of timing from the moment the helicopter was released until it touched the ground. They averaged out their times, and free-handed a bigger helicopter to see how it fit with their data. To no one’s surprise, the bigger helicopters resulted in a slower movement downward. This lab launched the Physics students into the math portion of projectile motion, calculating time, displacement, velocity, and acceleration!
