Activity 01
Demonstration: Bouncing Ball Transformations
Drop rubber and plastic balls from 1 metre height onto a hard surface. Students record bounce heights, listen for sounds, and feel for warmth after multiple bounces. Guide a class chart of energy shifts from potential to kinetic, then to heat and sound.
Differentiate between kinetic and potential energy with examples.
Facilitation TipDuring Bouncing Ball Transformations, remind students to measure bounce height with a ruler and touch the ball after each bounce to feel warmth from friction.
What to look forPresent students with images of common objects or scenarios (e.g., a stretched rubber band, a car driving, a light bulb on, a person singing). Ask them to write down the primary form(s) of energy present and one possible transformation occurring.
