Question: Shadows are caused
A: when light is reflected onto a surface
B: when light from a source is blocked from hitting a surface
C: when sunlight is very strong
D: when the dark moves to one place
Answer: B
I would want to find out if they have understood that shadows are formed from a lack of light rather than the shadow being created out of something.
If the children haven’t spotted the “light being blocked” answer then that group of children would take torches and a few lego pieces to repeat the investigation with close support from an adult.
