This week in Science our Year 9 students explored the topic of physics by creating a ‘Wave Machine’. Students started their focus on waves and highlighted the differences between the two classifications of waves. In our modern world, we see vibrations on stringed instruments and ripples on the surface of water which are examples of ‘transverse’ waves.

Students also studied examples of ‘longitudinal’ waves which include sound waves and ultrasounds. After creating a class ‘wave machine’ using skewers and jelly babies, students were able to increase the wavelength, frequency as well as speed. It was a great way to delve into the physics curriculum with a very sweet hands-on task. Click here to watch the experiment unfold.
