Yesterday we had a visit from the Science Roadshow. The focus of the session was Sound Waves.
Some of the main messages about Sound Waves were that they can be low pitch and high pitch because the sound is trapped. They gave us an example with popping a balloon outside a jar and one inside a jar. When it was outside it was really loud and when it was inside it was quiet.
Something I enjoyed the most was all the activities, especially the Kinetic Sand and the rotating chair because the Kinetic Sand was so satisfying and fun to play with and the rotating chair was fun because we sat on a chair with weights and we would spin and have to put the weights up and down.
My favourite part of the Science Roadshow was the shows we did because they were so funny and learnt lots.
Something I will take away from this visit was that sound travels through waves because I did not know sound can travel.
What happens if a balloon is inside a jar and you pop it?
Hi Monica,
If a balloon is popped in a glass jar then it will make a tiny squeak noise. The rotating chair looks like a lot of fun.
Did you get a chance to go on it?
