Physics Lab: Build a Parachute

Physics is really exciting to teach because there are so many fun labs you can do. After teaching students about speed, velocity, and acceleration I wanted to do a STEM lab to follow up the unit. I decided to have students build a parachute out of a plastic grocery store bag and gave them a goal of keeping it in the air as long as possible. It was not only fun for them but the materials were super inexpensive! I supplied string and tape, and they had to supply the bag and any other materials they wanted to add. You are welcome to set size or material restrictions but I chose not to. I gave them one class period to build (if they didn’t finish they had to finish at home) and we tested the following day. When testing the parachutes I tied a GI Joe to the bottom to add some mass but you are welcome to use whatever you have handy (metal washers work great too). 

Parachute lab from Science Lessons That Rock

Our school is 2 stories so the students dropped their parachutes from the 2nd story. When they went to drop the parachutes they had 1 rule: No throwing the parachute up in the air. They had to hold their hands straight out horizontal and drop straight down.
Each group got to drop their parachute 2 times. They had to calculate the speed of the drop (distance / time) and acceleration (Vf – Vi) / t. Overall they had a blast and I had some silly prizes for the winner of each class period. If you would like to check out the lab worksheet I used CLICK HERE. Have fun!
