Sound waves

Last week we learnt about the way sound travels via sound waves into our ears. It is rather a complicated process so we learnt the basics.

We started the week by trying to identify various sounds from around the house. Some were really easy, others more tricky. It was such fun!

We saw visable evidence of sound waves when we
loudly bashed a baking tray right next to the rice.
It began to bounce up and down.

 


Both Megan and I have been teaching our children to write up a few of our class experiments. It has been  challenge for some children, but we are so impressed at how their skills are improving.

Our Friday Experiment.
We made a liquid xylophone to
demonstrate this.

Miss Caddick demonstrates
the different sounds the various
densities make.

Everyone really had fun with this.
