TALK ABOUT
Why does wet paint smell but dry paint doesn't?
The liquid in the paint has a smell. When the liquid evaporates it becomes a gas. Our noses can smell the gas in the air. When the paint is dry, the smell disappears because all the liquid has evaporated.

COMMON MISCONCEPTIONS
The most common misconception about evaporation is that the water disappears and does not exist any more, or that it changes into air or dries up and goes into the air. This is due the fact that learners cannot see where the water has gone. You will need to explain that the water evaporates, changing from a liquid to a gas.
