FILTERING BY
EVAPORATION
Children can watch this activity. It could be a way to get a bad steam burn, if the person doing it is not careful. This is still another way of filtering. The tea kettle has a sugar solution in it. When it boils, steam will come out of the spout. Using tongs to hold a cookie pan over the spout, we'll catch the steam on the pan. The pan will be held on a slant, so the condensed vapor (that is steam that turns back into water when it collects on a cold surface) can be collected in a bowl. Once the condensation (say "con-den-SAY-shun") cools, we can taste it. Is it plain water, or is it sweet? Does it taste the same as the cooled solution in the kettle? What happened?
