Four fun and interesting lesson ideas on teaching light and sound for KS1 and KS2 pupils.
Year 5-6 teacher David Aston, shows how glass bottles and water inspire pupils to think about how sound travels and how pitch can be altered.
He also demonstrates that sound travels by vibration by showing pupils what happens when you cross a string and a wire coat-hanger.
For KS1, Kate Widdowson makes use of torchlight and a range of materials so that children can predict and test the best light-blocking fabric for the "three little pigs' home".
Finally, Year 5 teacher Lucy Blackmore helps her class discover that light travels in a straight line whilst her pupils construct their own periscopes to solve a real-life problem.
