Video summary

Two children meet Curious Cat, an animated cat who asks them if they would like to find out how glass is made.

They take a trip to a glass making factory and to start learn about the raw materials used to make it, such as sand, soda ash and limestone.

The different stages and processes involved in making a flat pane of glass are seen, including the 'float glass process', which makes the molten glass flat and smooth.

This is demonstrated in a laboratory using oil and water. The children watch the raw material go in and the glass come out after which it is cut into different sizes.

This is from the series: Curious Cat Wool, Glass, Paper

Pupils could investigate how different shapes are made out of glass.

It could provide a discussion point around the strength of flat and round objects and their uses.

Pupils could investigate the same objects or size of objects made from different materials and think of an investigation to test their strength.
