We have a right to learn new things

Primary 6a have been learning all about sound and the classroom was buzzing (literally) with the sound of bells as we carried out some tests to see which materials make the best sound-proofing.

Each group wrapped an alarm in different materials, placed it in a box and then measured how far they could go before the stopped hearing the alarm.  We discovered that although bubble wrap is pretty good, foam is the best muffler of sound.

Next, we have been given a challenge to find out how different animals communicate with each other through solids, liquids and gases.
