About Light and Dark
- Light can be very bright or it can be very dark.
- When light is very bright it can hurt our eyes. Light from the sun is very bright and we shouldn't look at the sun because it can cause people to go blind.
- When there is not enough light to see we say it is dark. At night time it is very dark which is why it is hard to see.
