On Wednesday Grades 4T and 4J were lucky enough to have parent expert Andrew Perkins, a sleep scientist, come and speak to them. The students – and teachers – were fascinated by Andrew’s talk. He discussed why we sleep, how sleep works and the sleep patterns of different animals. He also wired up Ivy to a sleep recording device, to show how brain waves and breathing patterns are recorded and analysed so, as a sleep scientist, he can help people who have sleep problems. Thanks for coming in and sharing with us Andrew!
