Physics: Good Vibrations

This week we started a new topic: SOUND. 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 sides of tables, and struck water-filled glass jars, noting in each case which changes affected the pitch. Finally, the kids used their observations to created their own instruments, and then we had a concert!
