- 2. What is matter? Matter is anything that has mass and takes up space.
- 3. SOLIDS
- 4. SOLID A solid is matter that has that has definite size and shape. Example: Put a sneaker in a box. It stays the same.

- 11. Volume Measurement of the amount of space an object takes up • Measured in milliliters (ml) o litre (l)
- 12. Which do you think would have the greater volume? The greater mass? Why? 1 kg of feathers 1 kg of rocks
- 13. Properties of matter • HARDNESS • FRAGILITY • ELASTICITY • DENSITY
- 14. Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume. Density
