Year 4 investigate sound

Year 4 investigated sound today. They had to observe what happened to rice grains on the top of a drum when the drum was struck. They observed what happens when you twang a ruler on the edge of a table and they explored what would happen to the sound if the length of the overhang of the ruler changed. They blew into tubes with a tight piece of balloon over the end to feel the vibrations and they blew over the top of bottles and compared the sounds they made when different amounts of water was added to the bottle. Lots of collaborative work, discussion, listening and questioning. A great morning!
