Teaching guide, sample answers and curriculum references
Before you begin
Observe whether a material holds its own shape and volume.
How to use this worksheet
- Model the target skill: differentiate the three common states of matter: solid, liquid, and gas. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Observe whether a material holds its own shape and volume.
- Discuss an incorrect response using this distinction: A liquid takes its container's shape while retaining a nearly fixed volume; that differs from a gas.
A common mistake to discuss
A liquid takes its container's shape while retaining a nearly fixed volume; that differs from a gas.
What to practice next
Compare the same material in two states and describe the observable change.
