Properties of Solids
Solids have a fixed shape and volume. They do not flow and cannot be compressed easily.

Slide 5 - Slide

This item has no instructions

Properties of Liquids
Liquids take the shape of their container and have a definite volume. They can flow and are not easily compressed.

Slide 6 - Slide

Changing States: Melting and Freezing
When a solid is heated, it melts and turns into a liquid. When a liquid is cooled, it freezes and becomes a solid.

Slide 8 - Slide

This item has no instructions

Changing States: Evaporation and Condensation
When a liquid is heated, it evaporates and becomes a gas. When a gas is cooled, it condenses and becomes a liquid.

Slide 9 - Slide

This item has no instructions

Changing States: Sublimation and Deposition
Some solids can change directly into gases without becoming a liquid first (sublimation). Gases can also change directly into solids (deposition).

Write down 3 things you learned in this lesson.

Slide 12 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 13 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 14 - Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
