1. Classifiying Matter

2. Types of Matter Notes Sort
Using prior knowledge, sort the slips to match up with the correct category.
When finished, brainstorm three examples of each.

3. TYPES OF MATTER
physically
separable
chemically
separable

4. PROPERTIES OF MATTER What is matter?
What is mass?
Anything that has mass and takes up space
The amount of matter an object contains

5. SUBSTANCES
A substance is matter that has a definite and uniform composition
Substances have identical intensive properties.
One type of “stuff”

6. More than one type of “stuff” together
MIXTURES
A mixture is a physical blend of two or more substances. They can be physically separated.
How can you separate a mixture?
More than one type of “stuff” together
One type of “stuff”

7. HETEROGENEOUS vs. HOMOGENEOUS
There are two different types of mixtures.
A heterogeneous mixture is one that has more than one phase (part of uniform composition)
A homogeneous mixture has only one phase.

8. MIXTURES
physically
separable
Not uniform
Uniform throughout

9. HETEROGENEOUS OR HOMOGENEOUS?
Saltwater
Spaghetti sauce
Muddy water
Cough syrup
Salad
Brass

10. TYPES OF SUBSTANCES ELEMENTS COMPOUNDS AND
There are two different types of substances:
ELEMENTS
AND
COMPOUNDS

11. Substances
Unlike mixtures, substances are made of exactly one type of matter throughout.
How can you tell it isn’t a homogeneous mixture (with one phase?)
They cannot have a variable composition.

12. ELEMENTS An element is the simplest forms of matter.
Each element is represented by a chemical symbol.

13. COMPOUNDS
A compound is a substance that can be separated into simpler substances only by chemical means

14. Quick Lab Activity
With your lab parter, go to each of the 15 stations.
For each station, observe the materials put out and determine if it is a substance or a mixture.
If a substance, determine if it is an element or a compound.
If a mixture, determine if it is heterogeneous or homogeneous.

15. Substances By Station Oil and water Copper wire
Calcium carbonate (chalk)
DI Water
Kool-aid
Rocks and sand
Aluminum foil
Balloon full of air
Brass
Zinc metal
Saltwater
100% ethanol
Helium (tube)
Block of wood
Graphite

16. Post Activity Questions
Which was the easiest category to identify? Why?
What would you have to do to decide whether a substance was an element or compound?
How could you tell the difference between homogeneous mixtures and a substance?
