Water Cycle and Evaporation Science Fair Ideas
Water Cycle and Evaporation Science Fair Ideas

The water cycle is an interesting science fair project idea within earth science.


The water cycle may not sound as interesting as other earth science ideas, but there’s a lot to learn. Your child can set  up an experiment about evaporation, looking at different factors that influence how it works. He could also explore how pollution or salinity affect the water cycle. One of the best water cycle and evaporation science fair ideas I've seen was a student who became a water droplet and took the "Trip of a Drip."
