Can You Hear the Sound?
Posted by Cindy on January 16, 2010
We finished learning about sound this week. As with the color and light part of the unit, lots of hands-on experiments and demonstrations made for fun learning. Below are some of our activities, although I didn’t get as many pictures this week for some reason.
We experimented with pitch based on the amount of air available for vibration in the jars. The more air to vibrate, the slower the sound waves move. Slower sound waves = a lower pitch.
Several activities helped us to see, hear and feel sound wave vibrations. This is the classic cup and string phone.
Sound waves can bounce off of objects or be absorbed into objects. The kids had to design various experiments to prove both facts.

And, finally, here’s the resource list that’s been in the sidebar. For those of you following my unit study posts, the spines for the unit turned out to be two books I checked out from the library that included wonderfully illustrated experiments with explanations that covered just about every topic I had hoped to cover. The list below includes the extras that helped me fill in when needed.
The spines were: Science For Fun: Light & Color
Light, Color and Sound
