1. Matter
Chapter 1

2. Matter Anything that has a volume and mass
Volume is the space that the object takes up
Mass is the amount of matter in an object

3. Law of Conservation of Matter
Matter can neither be created nor destroyed. It just changes form.

4. Weight and Gravity Weight is mass times the pull of gravity
Metric unit for weight is newtons (N)
Gravity- the force of attraction between objects that is due to their masses
Gravity depends on two things
Mass of the objects
Distance between them

7. Put in order of increasing attraction to the earth
Elephant
Car
Fly
Squirrel
Mr Rush
Pin
Why did you put them in this order?

8. Inertia The tendency of an object to resist a change in it’s motion
Objects at rest remain at rest, objects in motion remain in motion unless a force acts upon the object
Newton’s 1st law
Objects with larger mass have more inertia

9. Put in order of increasing inertia
Elephant
Car
Fly
Squirrel
Mr Rush
Pin
Why did you put them in this order?

10. Describing Matter chpt 1 section 2
Play 20 questions with the person sitting next to you

11. Activity
On a piece of paper, write a description of something in the classroom.
Make sure you use a lot of detail without actually giving away what you are describing
Give your paper to someone else and have them draw your description exactly how you described it

12. Properties of Matter
Matter can be described in terms of both physical and chemical properties

13. Physical Properties
Can be observed or measured without changing the identity of the matter
Ex. Color, mass, shape, odor, texture etc

14. Physical Property: Thermal Conductivity
Ability to transfer thermal energy from one area to another.
Poor conductor, so hot chocolate does not burn your hand!

15. Physical Property: State
The physical form in which a substance exists, such as a solid, liquid, or gas.

16. Physical Property: Malleability
Ability to be pounded into sheets

17. Physical Property: Ductility
Ability to be drawn or pulled into a wire.

18. Physical Property: Solubility
Ability to dissolve in another substance.

19. Physical Property: Density
mass per unit volume

20. Chemical Properties
Describe a substance based on its ability to change into a new substance with different properties
Ex. Iron + Oxygen = Iron Oxide (aka rust)

23. Physical versus Chemical Change
Identity of a substance does not change
Can be reversed
Chemical
Identity of the substance changes
Cannot be reversed
