This project allows students to visualize sound waves by observing how rice moves on a drum surface when the drum is played. The experiment highlights the concept of sound vibrations.
If I play a drum covered with rice, then the rice will move in patterns due to sound vibrations.

Stretch plastic wrap over the top of the drum.
Secure the plastic wrap with rubber bands.
Sprinkle rice evenly on the plastic wrap.
Tap the drum softly with drumsticks.
Observe the movement of the rice.
Play the drum at different volumes and observe changes.
Experiment with different tapping speeds.
Record observations for each variation.
Draw conclusions about sound wave patterns.
Clean up rice and plastic wrap after completion.
The rice will visibly move and form patterns on the drum surface when sound waves are produced, demonstrating how sound vibrations travel.

Ensure that drumsticks are used carefully to avoid damage or injury.
Use a video to show the rice movement in action.
Include diagrams of sound wave patterns.
Discuss the science behind sound vibrations in simple terms.
