Hands-On Experiments

Interactive experiments to explore physical science concepts through hands-on activities.

Module 9: Waves and Sound

Experiment 9.1: Sound Wave Visualization

Beginner

Question: Can we see the effect of sound waves traveling through air?

Observe how sound waves travel through air by watching their effects on a candle flame and rice grains. This experiment demonstrates the physical nature of sound waves and their ability to transfer energy.

Materials: Plastic wrap, candle, rice, large bowl, wooden spoon

⏱️ 15-20 min ⚠️ Adult supervision
