Now we investigate together. You'll rotate through three stations and record what you see.
| Station | What to do | Question to answer |
|---|---|---|
| 1. Melting | Watch ice / chocolate under the lamp | Can it become solid again? |
| 2. Dissolving | Stir sugar or salt into warm water | Where did it go? Is it still there? |
| 3. Evaporating | Discuss the salt-water dish left to dry | What will be left behind? |
