Inquiry Learning: Evaporation

We are learning about the process of a liquid turning into a gas - evaporation. We found out that you need to heat the liquid water up to make it turn into a gas. That is why hot water makes steam! The steam is the water vapour as it evaporates.

We made puddles on the warm concrete and drew around them with chalk so we could remember the size of the puddle we made.








Check out what our puddles looked like only 15 minutes later...



What has happened to the water?

We drew around what was left of our puddles.

This group made an interesting puddle because part was in the sun and part of it was in the shade.
Why did only the water on the sunny part of the concrete evaporate?


What's left of Room 3's puddles one hour later.
Kids, tell us in the comments below what has happened to the liquid water?






This puddle was still there 3 hours later! 
Kids, why you think it took so long to evaporate?
