Natural Science Portfolio - Day 1

Everything around you is made up of MATTER. 

Matter can exist as a liquid, a solid or a gas.

1. Gases do not have a definite shape or volume. 

They fill the containers they are put in.

2. Liquids do not have a definite shape but they have a definite volume.

3. Solids have a definite shape and a definite volume.

- Matter can go through physical changes. 

One example is a change of shape.

Another example of a physical change is a change of state.
