What you need
- A small ball (like a tennis ball or marble)
- A ruler or measuring tape
- Different surfaces (carpet, tile, wood)
How the activity runs
- Gather a ball, a ruler, and different surfaces (carpet, tile).
- Roll the ball gently on a flat surface and watch its motion.
- Push the ball harder and observe the change in speed.
The learning connection
Hands-on experiments make abstract concepts tangible and relatable. Engaging in practical activities helps reinforce learning and retention of scientific principles.
Try it with your learner
1. Gather your materials and find a flat surface. 2. Roll the ball gently and watch how it moves. 3. Push the ball harder and observe the change in speed. 4. Roll the ball on different surfaces like carpet and tile. 5. Note how the surface affects the ball's motion. 6. What did you notice?
