An outdoor experiment in which students observe, record, and explain why their shadows change throughout the day. 

In this activity, which must take place in the playground on a sunny day, pupils look at their shadow at different times of the day and measure differences in its size and direction. You can use a compass or an online map to help work out which way is North on the playground before measurements begin. Students record their results in a table and in a bar chart or line graph and discuss why they see what they do.
