Resource Type Classroom activity

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.
