2. A characteristic property is something that is specific to that substance. (i.e. Density, melting point, boiling point) Non-characteristic properties are common to many substances. (i.e. states of matter, temperature, volume, mass, acidity and alkalinity)

3. States of matter : (solid, liquid or gas) Mass : the quantity of matter of the substance Volume: the space that matter occupies Temperature: quantity of heat an object or matter contains Acidity and alkalinity : determines whether a substance is an acid, a base or neutral in its chemical composition.

4. Solids: - Particles held tightly together by chemical bonds - Particles cannot move freely. Only vibrate

5. Liquids: - Particles held weakly together (compared to solids) - Particles can move slightly with respect to each other.

6. Gases: - Particles are far apart from each other. - Particles move freely

7. Matter is composed of particles that are invisible to the naked eye.

8. Metre : (m)  Length Kilogram : (kg)  mass Gram : (g)  mass Second: (s)  time Litre (L)  volume Millilitre (ml)  volume Cubic centimetre  cm 3

9. Definition : A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.

10. Mass is commonly measured by how much something weighs. But weight can change depending on where you are (such as on the moon) while the mass stays the same.

11. Mass stays the same...weight changes

12. With a partner answer the following questions relating to the states of matter. I will give you 15 minutes to write down your answers and then I will randomly pick a couple of teams to discuss their answers.

14. Question: Can two objects with the same volume have different masses?

15. Example: Coke (regular) vs. Coke (diet)

16. Two objects can have the same volume and different masses because while they might occupy the same amount of space they can have very different amounts of matter within that given space.

17. With a partner write down 4 examples of how some objects can have the same volume, but different masses. I will give you 8 minutes to write down your answers then I will randomly pick a few pairs to discuss their answers.
