Night eyes: an animal vision lesson
Pupils learn that we need light to see, and that night hunters have eyes that make the most of very little light.
Hook
Turn the classroom lights down. Ask: what can you still see, and what has gone?
Steps
- 5 minShow the photo through your own eyes, then through the tawny owl's. Pupils describe the differences.
- 5 minSwap to the cat. Pupils compare the owl and the cat: which picture is sharper, which keeps more colour?
- 5 minPupils draw an owl eye and a person eye side by side and label which is bigger for its head.
- 5 minTalk: with no light at all, nobody sees. Night eyes collect more of the light that is there.
The animals
Talk about it
Why can no animal see in a room that is completely dark?
A good answer
Seeing needs light that bounces off things into the eye. With no light at all, nothing reaches any eye, so no animal can see.
