Children enjoy learning about the science behind ice, steam, snow and related topics. While they can read about the science in a book, it's much better to demonstrate the principles while explaining them. Kids are much more likely to remember lessons that are hands-on rather than abstract.

Condensation is the process through which gas changes into a liquid when it touches a cooler surface. Condensation is an important part of the water cycle. It is the opposite of evaporation.

Condensation of water is when water changes from gas to a liquid or crystal shape. Any gas can condense, either because the temperature is dropping or the pressure is increasing. In either case the pressure of the condensing gas is higher than the vapor pressure of the gas, at that temperature).

During condensation, the molecules in the matter slow down. Heat energy is taken away, causing the state of matter to change.

Condensation is exothermic. This means that condensation makes the temperature go up. Evaporation is the opposite and causes a temperature loss.

It is a useful process. One use is in distillation. The gas made from a boiling liquid mix is sent to a condenser, where the different parts condense differently. This can purify a liquid, such as alcohol or water. The condensing liquid makes heat, which must be removed for the condensation to continue.

As the Sun heats water in a puddle, the puddle slowly shrinks. In a similar way, as water in a pot boils, the level of the water falls. These are two examples of evaporation. The water seems to disappear, but it actually moves into the air as a gas called water vapor.

Evaporation happens when a liquid is heated. The heat gives the liquid's molecules more energy. This energy causes the molecules to move faster. If they gain enough energy, the molecules near the surface break away. These molecules escape the liquid and enter the air as gas.
