1. SORT
CLASSIFICATION STATIONS
Move through the stations with your group. Investigate the station, and decide whether you have seen a physical or a chemical change.
What did you see?
FILM CANISTERS
EXPERIMENTS

- Cabbage water
- Milk and detergent
- Blowing up balloons
- Cream

CHANGES
PHYSICAL CHANGES...
- Are often reversible
- Do not create anything new
Everything is still there, just in a different state.
2.
PHYSICAL PARTICLE MODEL OF STATES OF MATTER
Groups report back on experiments from last week.

MIXTURES
Colloids and Suspensions
DISCUSS:

Suspensions:
- Mud

Colloids:
- Blu-tac
- Snakes
- Toothpaste

Some substances were difficult to classify in our investigation because they displayed properties of both solids AND liquids. Why?
There are three MAIN states of matter. However, these are not the only ones. Some of the substances yesterday were a misture of two different states of matter. This is why they showed properties of both. These substances can be seperated into colloids and suspensions.
Solution v Mixture Experiment
- Review the three main states of matter and physically model these as a group outside. - Interactive review quiz.
- Revisit classifications.
- Remind students that some have not yet been classified.
