Simple pendulum and gravity.
Galileo's pendulum experiment is one of history's most elegant proofs of a universal law. Replicating it with real equipment creates a direct link between the student's experience and the scientist's discovery — the pendulum becomes a memory anchor for gravitational acceleration.
1. Make pendulum 30cm. 2. Swing 10 times. 3. Record time. 4. Try 20cm. 5. Compare.
