Glass is useful because it keeps the wind and rain out but let’s in light. Glass is naturally transparent. This means you can see through it. Glass can be made in beautiful colours. Glass can also be made cloudy so that you can’t see through it.

 

 

 

 

 

 

 

Glass is easy to see through.

Transparent glass is used everywhere, from windows to the glasses that people wear to help them see clearly. In the past, some windows were so thick that it was difficult to see through them! Thick glass is less clear than thin glass. Glass that only allows some light to pass through is called translucent.

 

 

 

 

 

 

 

 

You can’t see through some glass!

Some glass only allows through a small amount of light. This cloudy glass is called opaque. It is used when people don’t want others to see in. Opaque glass is often used on front doors or in bathroom windows.

 

 

 

 

 

 

You can make your own stained glass window!

Collect some coloured sweet wrappers. Ask an adult to help you cut a window frame from black card. Use black sticky tape to stick the wrappers in the window. Put your frame on a windowsill and see the colours as the Sun shines through!
