Matter is everything that exists and is made up of different materials, either natural or artificial. There are three states of matter - solid, liquid, and gas. Mass is the amount of matter while volume is the space it occupies. Water is odorless, tasteless, and colorless and can change states between solid, liquid, and gas depending on the temperature. Mixtures occur when two or more substances are combined and can be either heterogeneous or homogeneous. Mixtures can be separated through evaporation or filtration. There are four types of waste - organic, recyclable, non-recyclable, and e-waste.

1. natural

2. What’s matter?
Matter is everything that exists. Matter is made up of different
materials. Some materials are natural and some are artificial.

3. What are the three states of matter?
There are three states of matter: solid, liquid and gas.

4. What’s the difference between mass and volume?
Mass is the amount of matter. Volume is the space matter occupies.

5. What are the characteristics of water?
Water is odourless, tasteless and colourless.

6. How does water change state?
Water is in a gas state at temperatures of over 100°C.
Water is in a liquid state between 1°C and 99°C.
Water is in a solid state at temperatures below 0°C.

7. What are mixtures?
A mixture happens when we put two or more substances together.
Mixtures can be heterogenous or homogeneous.

8. How can we separate mixtures?
We can separate mixtures by evaporation or by filtration.

9. How many types of waste are there?
There are four types of waste: organic, recyclable, non-recyclable and e-waste.
