This document defines and provides examples of the three states of matter: solids, liquids, and gases. It explains that solids have a definite shape and size, liquids take the shape of their container, and gases have no definite shape. Examples are given of a sneaker representing a solid, juice in a glass representing a liquid, and air representing a gas. The document also discusses mass, volume, density, and properties of matter such as hardness, fragility, and elasticity. An activity is assigned for students to complete and journal about.

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.

5. Liquids

6. LIQUID
A liquid takes the shape of any container.
Example: Pour juice into a glass. The juice will take on the shape of the
glass.

7. GAS

8. Gas
Gas is matter that has no definite shape. Gases take the shape of
whatever container they are in .
Example: The air all around us is a gas.

9. CHANGES OF STATES

10. Mass
Measurement of the amount of matter
(or stuff) in an object
• Measured in grams (g)
There are 3 states
of matter:
Solid
Liquid
Gas
There are 3 states
of matter:
Solid
Liquid
Gas

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.
