This week we talked about what a sound is and experimented with sounds produced by different materials. The kids made oboe-like straws, plucked rubber bands of different widths and lengths across shoe boxes, bounced wooden sticks off the side of tables, and struck glasses filled with water (looks like wine, but it's just food coloring, I promise!), noting in each case how different changes affected the pitch. Finally, the kids used their observations to created their own instruments, and then we had a concert!
