Science with Y4 and Miss Codd

We are learning about light and its effects.
We discussed how to measure a tower in secret so we could rescue a princess. If we knew the height of the tower, we could make a ladder to reach her. However guards were there all day. We wondered, ‘if we measured the shadow of the tower, would it be the same height as the real tower?’

 

 

We discussed our ideas in groups. We explained why different children and characters in the story had the right or partly right idea. We explained why different children and characters in the story had the wrong or partly wrong idea. We needed to know how shadows are made. We needed to know what the sun does to shadows.
