Glass, Plastic, Wood, Metal

We have been doing some more research into our four materials:
glass, plastic, wood and metal.
We tried to find out at least five facts about each.

We now know that glass:

• is a material made by humans
• is made by heating sand (just like the sand on the beach) and chemicals together
• is made in factories
• is used to make marbles
• lets light through
• can be transparent or opaque
• is used to make mirrors
• does not stick to a magnet
• feels smooth and cold

We now know that plastic:

• is a material made by humans
• can be made into many different things
• is made in factories
• can be very soft
• is made from oil which is found under the ground in rocks, pumped out using water and sent in pipes to a refinery
• does not stick to a magnet
• can last for ever

We now know that wood:

• is a natural material
• burns
• is used for furniture
• can be hard or soft
• can be heavy or light
• has bark which feels rough
• needs to dry out before it is used
• does not stick to a magnet

We now know that metal:

• can be hard and shiny
• can feel cold
• can be found in rocks
• can be magnetic
• can be used to make nail scissors and spoons
• is a natural material
• can be made by humans
• comes in different types like gold and silver
