3. Matter comes in three forms: solids, liquids and gases. Below are
examples:
4. Hardness: Diamonds are an example
of an hard material. What else can you
think of? It has to be a solid object and
very strong.
Toughness: This is when it can resist
breaking. For example A steel frame
can support parts of a building.
5. Fragile materials: Examples of fragile materials are glass and porcelain.
They could break very easily if your not careful!
6. Plasticity: Made from plastic
but has elasticity in the plastic.
A great example for this is a
drinking straw. You can fold
and twist the straw that is
made of plastic but it would
not break.
Some materials have a strong
elastic in them and they can
return to their original shape,
just like a rubber band.
