We are studying sound and different sound and how sound is made. We made telephones from plastic cups and string so we can see how sound travels. It was lots of fun. We worked with a partner and put a hole in the bottom of the cup to put the string through We had to tie knots in the end of the string so the string would stay and we could join it to the next cup.
Here we threaded through the string
We talked through our phones to each other.
