Take some time each day to watch the sky in the day and at night.
When you look at the sky in the day, watch the clouds. Can you spot different patterns? Draw a picture of the clouds or imagine that you can see pictures in the different shapes.
Learn about the moon and its different phases. Make some time to have a look for it each night. Maybe draw a picture of what you see.
See if you can spot stars you recognise and give them names.
