Different gases have different densities. Three balloons which are filled to the same volume with three gases (helium will float, air will hover and argon will sink to the floor). The helium can be found at any store which sells balloons. Finding the argon may be difficult. If there is a gas supply store in your area I'm sure they could fill one balloon for your experiment.

Boil water and put a clear glass lid on top of the pot. Let em see the condensation and take the lid off so they can see the vapor in the air.
