2. Refraction KEY WORD ALERT!
Level 4
Refraction is the bending of light as it passes from one substance to another. E.g. from a gas to a solid.
Level 5
Refraction is when light changes direction due to it moving from one medium to another.
Level 6
Refraction is when light changes direction due to it moving from one medium to another. This is due to the light changing speed when passing through the medium.

9. “Why is it difficult to shoot fish in a barrel?”
Learning Activity
“Why is it difficult to shoot fish in a barrel?”
HINT!
Think about refraction. What has that got to do with shooting fish in a barrel?

10. “Why is it difficult to shoot fish in a barrel?”
Teacher Explanation
When light passes from the water through to the air it changes the direction of the lights path. This makes the fish appear to be in a different position.
