We're putting pieces together here left and right! Now that we've built models for the air and water, and the water and the cups, we're putting the air, water and cups together! But there are a couple puzzling things to us:
1. How does the water get up into the air when it evaporates? Like where does it get the energy from?
2. What really distinguishes a water particle in the cup (liquid) from a water particle in the air (gas)? If they're both water, and we should represent them as the same particle, what's different about them?
One student questioned, "Is it the energy?"
Great thinking, kid! We're going to think about where these particles get their energy from!
