Extra Credit Alert (30 to 50 pts!) - Build a Wave Machine!

Build your own Wave Machine - this is a great physics demonstration for the classroom or at home as a brilliant science experiment for kids.

This science demonstration video is one of over 8,000 free teaching resources available for from the National STEM Centre following registration. Register here https://www.nationalstemcentre.org.uk...

The Wave Machine is also a fun and useful tool for the science classroom as it can be used to demonstrate transverse wave motion and is a great way of demonstrating how light waves change when moving through different media such as glass and air.
