Glass

This material is made from melting sand at a very, very high temperature.

Objects:

Windows, drinking glasses, marbles, jars.

Properties:

It is hard, stiff, smooth, and waterproof. It is usually transparent (you can see right through it).

💡 Fun Facts

  • Even though glass is hard, it is also brittle, which means it can smash easily if you drop it.
  • Glass can be recycled over and over again and it will not lose its quality.
  • Some glass, like in sunglasses, isn't fully transparent, but it's not opaque either.
