This week I am challenging you to build a den that blocks out light. Think about the material you are using – is it transparent or opaque? If you can’t build a den, design a den you could make and think about what materials you might use.
Another idea you could look at is to use shadows to draw pictures, like in the pictures below. Leave the item in the same spot outside and draw around the shadow in the morning, at lunchtime and in the afternoon. What do you notice about the shadows?
