1. Start with an empty, disposable water bottle, and fill it with Hot water. Make sure it is filled all the way to the top.
2. Let it stand, and watch to see if the water level changes as it cools down.
Can you see that this picture (above) shows the water level slightly decreased?3. Put the bottle in a water filled pot on the stove, and bring to a gentle rolling boil. Watch again to see if the water level changes now that the water is getting hotter.
We found that when the water got heated on the stove, it got bigger and began to overflow out of the bottle.Our conclusion: Yes water does change size: Hot water is larger than cold water.

It's fascinating to me that hot water is bigger than cold water, and frozen water is bigger than cold water. From what I understand, it's one of the only compounds that does that. I love science!
You are too cute!
