Aim: What characterizes homogeneous and heterogeneous mixtures?

Rules: homo or hetero

Write homo on one index card and hetero on the other

When you see an image on the screen, put up your card that represents the correct answer

I will then call on people to justify answer.

Aim: What characterizes homogeneous and heterogeneous mixtures?

Types of mixtures

Solutions:

When something is completely dissolved in water, it is called a solution

Aqueous solutions describe something dissolved in water

AQUEOUS = aq

Example: KNO3(aq)
