Core Skills Analysis
Science
- Identified how springs store and release elastic potential energy, linking to concepts of force and motion.
- Observed the role of material properties—metal strength and spring elasticity—in supporting safe weight limits.
- Applied measurement and geometry by aligning frame pieces, checking angles, and ensuring even tension across the trampoline surface.
- Explored basic engineering design principles such as stability, balance, and the importance of following step‑by‑step instructions.
Tips
Extend the learning by (1) measuring how high a ball bounces on the assembled trampoline and graphing height versus number of springs attached, (2) researching safety standards for playground equipment and creating a safety‑check checklist, (3) designing a mini‑trampoline on paper, labeling each component and explaining how each part contributes to energy transformation, and (4) conducting a simple experiment comparing bounce height on different surfaces to discuss energy loss and material friction.
