1. Matter and its Properties Read through the notes and fill out your concept map to classify matter

2. What is Matter?
Matter can be defined as anything that has mass and takes up space.
All matter has mass and volume.
Volume is the amount of 3-D space an object occupies.
Mass is a measure of the amount of
matter in an object.

3. Classification of Matter
There are 2 ways you can classify matter.
Pure Substances
Mixtures

4. Pure Substances
Consist of elements and compounds.
An element is a pure substance made of only 1 kind of atom.
An atom is the smallest unit of an element that keeps the properties of that element.

5. EXAMPLES
Carbon, Hydrogen, and Oxygen are all examples of individual elements.
Each element specifically contains only 1 kind of atom.
**This makes each element a pure substance.

6. The Compound…
A compound is a substance that is made of 2 different elements that are chemically bonded.
Compounds consist of molecules.
Ex} Water is an example of a compound. It is made of 2 elements, hydrogen and oxygen. The atoms of Hydrogen and Oxygen are chemically bonded to form a water molecule.

7. Mixtures…
A mixture is a blend of 2 or more kinds of matter, each of which retains its own identity and properties.
The can be classified as:
homogeneous
heterogeneous

8. Homogeneous Have a uniform composition
Meaning they have the same proportion of components throughout or they are mixed evenly.
Homogeneous mixtures are also known as solutions.
Kool-Aid Salt water

9. Heterogeneous Are not uniform throughout..
Meaning the particles are unevenly distributed.
Clay& Water Seeds

10. Heterogeneous Mixtures
Suspension
heterogeneous
large particles
particles settle
EX: fresh-squeezed lemonade, Baby medicine

11. Heterogeneous Mixtures
Colloid
heterogeneous
Strong Tyndall effect
particles don’t settle
EX: Whip Cream, Butter, Fog, milk

12. Tyndall Effect

13. Separating Mixtures Can be separated by physical means such Sorting
Filtering
Boiling/Distillation
Evaporation
Melting
Chromatography
Paper Chromatography
Sorting erasers
Filtering- Oil

14. Separating Mixtures
Distillation Set-up

15. On the Back of your Concept Map:
Define the following terms:
Colloid (and list the examples)
Suspension (and list the examples)
Tyndall Effect
Copy: “Mixtures can be separated by physical means such as:” and then list the ways…
