Intro to Mixtures Ms. Rowland Ms. Khericha

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.

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.

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

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 Diagram: Examples: Kool-Aid Homogenized Milk, Blood

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: gold, silver, water, salt

Solute Definition: the substance which dissolves in the solvent to form a solution. Diagram: Examples: sugar or salt stirred into a glass of water

Solvent Definition: the substance in which the solute dissolves to form the solution. Diagram: Examples: water, ethanol, acetone (anything that will dissolve other materials)

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.
