Digital Dudes: Can you explain the science of what happens when paint dries?
You might need to use words like...
- evaporation
- molecules or atoms
- gas
- liquid
- water
- paint
We learned more about what molecules are. Check out this short movie that helps explain atoms and molecules.
This website shows what happens to the atoms (or molecules) in water when the temperature is changed. What the temperature on the graph change as the water changes from a solid to a liquid then to a gas.

ReplyDeleteThe water molecules dry up in the sun. The paint molecules remain stuck to the paper.
