3. Non Matter Anything that doesn’t have a mass and volume, such as light (diagram 2). Diagram 2:

4. Pure Substance A substance that’s unbreakable into other substance that always has the same properties, such as crystals (diagram 3). Diagram 3:

5. Element A pure substance that’s unbreakable into other substances that have only one kind of particle, such as gold (diagram 4). Diagram 4:

6. Compounds A pure substance consists of two or more different elements that have only one kind of particle, such as solid, liquid or gas (diagram 5). Diagram 5:

7. Mixtures Any substance that have two or more pure substance, such as milk (diagram 6). Diagram 6:

8. Heterogeneous Mixtures Elements that aren’t the same kind of ‘Mixtures’, such as cereals (diagram 7). Diagram 7:
