Human Sundial
In this activity, from the Royal Observatory Greenwich, students look at their shadow at different times of the day and measure differences in its size and direction. The activity needs to take place in the playground on a sunny day. A compass or an online map can be used 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.
