1. Intro to Mixtures
Ms. Rowland
Ms. Khericha

2. Observations
Your group has been given a tray with 4 beakers containing different substances.
Observe the substances in each beaker
Write your observations on your notes for today
You will have 5 minutes to work on this activity.

3. Definitions, Diagrams, and Examples
For each type of substance, you will need to write the definition, draw a diagram, and list examples. Please make your diagrams as detailed as possible.

4. Heterogeneous Mixture
Definition: a mixture where the components of the mixture are not uniform or have localized regions with different properties.
You can see the parts that make it up
Diagram:
Examples: iced tea, salad, tacos

5. Homogenous Mixture
Definition: a mixture where the components that make up the mixture are uniformly distributed throughout the mixture.
You can’t see the parts that make it up

Blood

6. Pure Substance
Definition: a substance that consists only of one element or compound. It does not contain any other substance in any proportions.

Diagram:
Examples: water, ethanol, acetone (anything that will dissolve other materials)

10. Activity You will be taking a gallery walk around the classroom.
You will be given a sheet of paper where you will label what the item is, whether it is a heterogeneous mixture, homogeneous mixture, a pure substance, a solute or a solvent.
After 10 minutes we will discuss what each item is.
