Light and Sound

This week we are exploring light and sound! As part of our exploration of light we used a prism to separate sunlight into the colors of the rainbow. Children also used mirrors to bounce light from one surface to another, and found out what they looked like in a mirror that was convex or concave. Other students used a flashlight and colored plastic paddles to change the color of light.

When energy causes an object to vibrate, the vibrations travel through the air to our eardrums, and we hear a sound! We investigated sound in several different ways. Using a Slinky, we tried to imagine how sound travels through the air in waves. We explored the connection between the size and shape of an object and the sounds it can make, trying out a rubber band and box “guitar” and listening to the pitches of tuning forks.
