Listen carefully. First I will clap softly. Now I will clap more loudly. What changed?
Now listen to this drum. Soft hit. Harder hit. How could we make this drum quieter or louder?
That soft clap was a quiet sound. The strong clap was a loud sound. Quiet means soft and harder to hear unless you are close. Loud means strong and easy to hear. Things that make sound often wobble a little. Next we will try hard and soft hits on the same drum.
Our question: which is louder on the same drum, a soft hit or a hard hit? Say your prediction and one reason. Hands up when you are ready to share. Then mark your prediction on your Investigation Journal page before we try it.
In your group, use the same drum or tin with a skin. Hit softly, then hit harder. Listen from the same spot. Feel the top with a light finger after each hit. Which felt like a bigger wobble? Which sounded louder?
Look at the drum on the board. Watch what happens to the wobble when the hit gets harder. Did the sound get louder? Does it still sound like a drum?
