2. Vocabulary Matter – anything w/ mass & takes up space.
Mass – amount of matter
Volume – amount of space
Physical Property – describes a substance (malleability/solubility)
Chemical Property – describes ability to change or react (flammability)
Physical Changes – does NOT change the identity (only appearance).
Chemical Changes – changes into a new substance, rearranges atoms
Combustibility – how easily something bursts into flame/explodes
Malleability – ability to pound into sheets or bend into shapes

3. Vocabulary
10. State of Matter – solid, liquid, gas or plasma 11. Solid – definite shape & volume, particles vibrate. 12. Liquid – No shape, definite volume, particles slide 13. Gas – No shape or volume, particles move freely 14. Plasma – Super heated gas, conducts electricity 15. Kinetic Theory of Matter – All matter has particles that move depending on the amount of energy they have. 16. Solubility – ability to dissolve 17. Precipitate – a solid that is produced from 2 or more liquids reacting. 18. Law of Conservation of Mass/Matter – Matter cannot be created or destroyed. Mass of Reactants must = Mass of Products

4. Oops! We missed some!
Reactivity is a chemical property that is the ability of one substance to react with another.

g/Cm3
g/mL

6. Water Displacement Practice
11 mL – 8 mL = 3 cm3 Volume of Cherries

7. Water Displacement Practice
24 mL – 8 mL = 16 cm3
Volume of Balloon

8. Water Displacement Practice
9 mL – 6 mL = 3 cm3
Volume of Carrot

9. Water Displacement Practice
14 mL – 5 mL = 9 cm3
Volume of Artichoke

10. Mass, Volume, Density continued…
The density of water is 1 g/mL
An object with a density LESS than water (or any liquid) will FLOAT.
An object with a density MORE than water (or any liquid) will SINK.

11. States of Matter Gas Particles move freely Liquid
Particles slide around
Plasma
Particles ionized, conducts electricity
Solid
Particles vibrate

12. C
Physical vs Chemical P C P P C

13. Indicators of Chemical Changes
color
odor
temperature
gas
precipitate

14. Law of Conservation of Matter/Mass
The wood & oxygen burn to make ashes, CO2 & water (H2O). The mass of the reactants is the SAME as the mass of the products!

15. Oops! We missed some! Weight is measured in Newton’s.
Weight is measured using a scale.
Weight can change based on an object’s position in the universe.
Weight changes due to gravity.
