Precipitation was introduced using a precipitation chart off of the internet.  Students received a copy of the chart for their notes and to follow through the explanation. The internet was used to show the different kinds of precipitation, the need for precipitation and how destructive mass amounts of precipitation can be.  Evaporation, condensation and precipitation were then demonstrated through the ‘Be a Tropical Rain Maker' experiment.

Notes taken from :

Student Notes:
Rising warm air carries water vapor high into the sky where it cools, forming water droplets around tiny bits of dust in the air. The drops freeze to the ice crystals, forming larger crystals we call
snowflakes.   If snowflakes completely melt in the warmer air, but temperatures are below freezing near the ground, rain may freeze on contact with the ground or the streets. This is called freezing rain. There is another kind of precipitation that comes from thunderstorms called hail.

Precipitation Paragraph


Be a Tropical Rain Maker!
Try this experiment, but only with adult supervision::
Boil  water in a tea kettle.  Watch the steam come out and go into the air. (Evaporation)
Put ice in a metal pie pan.  Hold the pan over the steam and watch the drops form on the bottom of the pan. (Condensation)
As the drops grow in size, they will get heavy and start to fall. (Precipitation)
