​S8P1- Obtain, evaluate, and communicate information about the structure and properties of matter.
a. Develop and use a model to compare and contrast pure substances (elements and compounds) and mixtures.

Learning Target

I can explain the difference between a pure substance and a mixture.

Success Criteria

Complete a graphic organizer explaining the differences between a pure substance and mixture.

two or more substances physically combined (variable composition)

Mixture

all particles in matter are identical (fixed composition)

Pure Substance

​anything that takes up space and has mass

• Matter is either a pre substance or a mixture

Two or more elements chemically combined in a fixed proportion
- can be broken down by a chemical reaction
has different properties than the elements it makes up

Compound

Simplest form of matter
Can be found on the periodic table

Element

Two or more substances chemically combined

Compound

Just one substance; the simplest form

Element

substances in the mixture are not evenly spread out

• Different components are easy to see, or separate out over time

• Ex. Salad dressing, paint, cereal

Heterogeneous

components are evenly distributed out on a microscopic level

• Solutions (when one substance is dissolved into another) are homogeneous mixtures

• Usually appears “blended”

• Ex. Bleach, lemonade, coffee

Homogeneous

uneven distribution; "different"

Heterogeneous

even distribution; "same"

Homogeneous
