Light and Sound
From Teachers TV, this video shows four examples of lessons on light and sound that are suitable for primary school children. Part of the Great Lesson Ideas series, it contains these ideas for lessons: Years Five and Six teacher David Aston, shows how glass bottles and water inspire children to think about how sound travels and how pitch can be altered. He also demonstrates that sound travels by vibration by showing children what happens when you cross a string and a wire coat-hanger. For Key Stage One, 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. Year Five teacher Lucy Blackmore helps her class discover that light travels in a straight line whilst her children construct their own periscopes to solve a real-life problem.
