ACTIVITY in Separating Mixtures, Physical Properties, Temperature, Sublimation, Gas Laws, Pressure, Phase Changes, Physical Change, Review, Distillation, Boiling Point, Volume, Mixtures. Last updated March 25, 2020.
In this activity, students will play a game to review topics relating to physical properties of matter, including mixtures, states of matter, and gas laws. They will be prompted with questions in a PowerPoint and they will use white boards to communicate their answers.
By the end of this lesson, students should be able to:
- Describe the properties of different states of matter and their associated phase changes.
- Provide examples of different kinds of mixtures.
- Describe techniques for separating mixtures.
- Perform calculations using gas laws.
This lesson supports students’ understanding of:
- Physical changes
- Physical properties
- Phase changes
- Gas laws
Teacher Preparation: minimal
Lesson: 30 minutes
- White board
- White board marker
- Eraser or paper towel
- No specific safety precautions need to be observed.
- This PowerPoint presentation can be modified to host a similar review game on a different topic.
- Sample questions:
- Which is a substance? (salt, salt water, oatmeal, a replacement teacher)
- You find the mass of a salad. Did you find an… (extensive or intensive property)
- Which substance has a definite shape and volume? [NaCl (aq), Cl2(g), CCl4 (l), AlCl3 (s)]
- Which of the following will sublime at STP? [SO2 (aq), H2O (l), CO2 (s), Ca (s)]
- Name at least 3 properties of all liquids.
- A liquid in a container is boiling at a pressure of 790 torr. The normal boiling point of this liquid will occur at what pressure?
