Milk Carton Vehicles is a STEM lesson focusing on Engineering Design principles, Forces of Motion, and simple machines. My goal is to make learning exciting and authentic. Students will build a milk carton vehicle to investigate different forces of motion. Students will be learning about simple machines, wheels and axles while building their vehicles. They will investigate the relationship between potential and kinetic energy by looking at how releasing a balloon that is attached to the car will determine how far the vehicle moves. Forces of friction will be tested by using different surfaces like aluminum foil, sandpaper, tile, and carpet. Students will also investigate inclined planes and how different slopes affect the motion of the vehicle. I like to discuss angles during this part of the investigation as well if your students are ready for it. There is part of the challenge where students can manipulate their design in order to carry a load, testing the amount of force that will be needed to move the vehicle when carrying a load. Students LOVE this STEM challenge and investigating forces of motion with a vehicle they designed. This purchase includes teacher directions on setting up materials with pictures, PowerPoint- turned into a PDF (can't be edited)that I used to hold discussion and lesson with students, task cards for student stations, and lab write-up for investigations. Enjoy!
