Mass and Volume
Objects and materials have MASS and VOLUME.
MASS is how heavy something is.
VOLUME is the space that something occupies.
Mixtures: homogeneous and heterogeneous mixtures
In a HETEROGENEOUS mixture we put two or more substances together but we can see them separately.
In a HOMOGENEOUS mixture we put two or more substances together but we cannot see each of them separately.
Properties and states of the matter
Materials have different properties; they can be:
- Hard or Soft
- Transparent or Opaque
- Rigid or flexible
- Waterproof or absorbent
- Elastic
- Magnetic...
We can change materials by HEATING, COOLING and BENDING them.
