Sound Experiments

Testing how to change volume and pitch using bottles filled with different amounts of water

We are learning how to be good scientists. We know that scientists ask questions about the world around them and then look for answers. To find answers they do tests, investigations and experiments. The results from their experiments help them find answers they can say are true. In our bottle experiment we found that the more water was in the bottle, the lower the pitch. A little water had a higher pitch. To change the volume we hit the bottles harder or softer.

Why not play this game which lets you experiment by playing different intruments and changing the pitch and volume.
