Investigating shadow sizes

By 08/03/2022Science, Year 3

In science, Year 3 have been busy preparing for our upcoming shadow puppet show. We wanted to ensure that we could alter the size of our shadows to make our puppet characters appear larger/smaller at different points in our performances. We investigated whether we could change the size of our shadows by altering the distance between the light source and the shadow puppet. To do this, we used our rulers to accurately measure the distance between the light source and the puppet and also, measure the width of the shadow. Before trying each distance, we predicted how wide we thought the shadow would be. Our results showed that the closer the light source is to the object, the bigger the shadow.
