UV Frisbees
This term we are investigating how and why we need to keep safe in the sun.
Today we used a special white frisbee to help us check whether we need to wear a sunhat on a cloudy day.
Our white frisbee changes colour to orange on contact with ultraviolet light from the sun.
The darker orange it gets the more you have to protect your skin from the sun.
Ultraviolet light harms our skin! Our frisbee turned light orange so we could see that some ultraviolet rays were shining down on us even though it was a cloudy day!
We are going to wear our sunhats even when it is cloudy!

Great visual way to show the children that it doesn't necessarily have to be sunny for UV Rays to burn us!
