Materials:
Empty juice bottles of different sizes
Water
Air
Procedure:
1. Arrange the empty juice bottles from the smallest to the largest.
2, Blow air into the bottles, and listen to the pitch of the sound.
3 .Fill each bottle with water up to the level marked on the bottle.
once again,
4. Blow air into the bottle and listen to the pitch of the sound.
Results.
Once water was placed in the bottles,, the pitch of the sound changed according to the size of the bottle each time we blew into it.
This also came about with empty bottles, just blowing air into them. We found the larger the bottle, the lower the pitch of the sound.
Conclusion:
From this experiment, I have learnt that air pitches at different levels when blown into different sized bottles.
