I have chosen the activity set ‘Stars’. I would introduce the topic by reading ‘How to Catch a Star’ by Oliver Jeffers. I would then ask the children to describe a previous occasion where they saw the stars. We would discuss what they know about stars already. I would play the first minute and a half of the video ‘What are Stars?’ (https://www.youtube.com/watch?v=ZrS3Ye8p61Y). I would ask them in pairs to guess how many stars they think there are. I would then give the children a photo of the night sky and ask them to count how many stars there are by separating the photo into sections and counting each section. We will discuss this and I will tell the class that there are so many stars that we need computers to count them for us and that in just our galaxy there are 100 billion stars.
