Homemade Trampoline Concepts

In this STEM class, students learn to create a homemade trampoline using household items like a colander, rubber bands, and a plastic sack. The video guides viewers through the setup process, emphasizing the importance of crisscrossing rubber bands and securing them with toothpicks. The instructor explains the physics principles behind trampolines, such as Hooke's Law and Newton's Third Law, highlighting how these concepts apply to the trampoline's function. Students are encouraged to experiment with their creations and share their results.
