What affects the rate of evaporation of water.Featured science projectScience project video

Conclusion

The hypothesis that the rate of evaporation of water will be faster with a larger surface area, higher temperature or lower air pressure environment, is proven to be true.

Evaporation is part of the water cycle. Water from the oceans evaporates and forms clouds in the sky. The wind blows these clouds towards the land where the water precipitates and falls as rain on to dry land. This water is collected in rivers and lakes as fresh water that we will eventually be used as drinking water. River waters flow back into the ocean and the process repeats itself.  

Also consider

The experiment can also be repeated using oil, alcohol and other liquids to compare the rate of evaporation.
