MATHS

We are continuing with our work on time today, but before we move on, if you want or need it, please have a quick recap on telling the time on an analogue and a digital clock.

We are continuing on with our work on LIGHT and SHADOWS.

This week, we are thinking about safety when dealing with light. 

The lights sensors at the back of the eye are very delicate and can be burned or damaged by very bright light.  So what ways can we protect our eyes from bright light?  Have a think for a minute.

- Wear sunglasses on very sunny days to protect you.

- Don't look directly at bright lights, including the sun.

The sun is a light source that contains heat as well as light.  Think about the sunburn that can be caused by the sun. Well, sunlight can burn the sensors in your eyes more quickly than it burns your skin because the back of your eye is much more delicate.  It is not safe to look directly at the sun, even when wearing dark glasses.

 Torches and laser pens  are very concentrated beams of light that can also damage the sensors in your eyes and they should never be shone into the eyes.  

TASK

Please design a poster about 'Light safety' that we can put up around school to remind children how they should look after their eyes and protect them fro bright light!
