Our science week topic was sound. So to start off the idea that sound is vibrations we observed how gloop reacts to being placed on a speaker. It wiggled and jumped about making the strangest shapes.
To test how vibrations and sound travel through solids we make string telephones.
Anna explains in her instructions for make making string telephones as,
1. First poke a hole into the bottom of both plastic cups.
2. Next attach the 2 cups by threading string.
3. Then tie a knot.
4. Hold the string tight a say "hello".
