Evaporation Collaboration

CSEF · 2007 Environmental Engineering

Tyler J. Newcomb · Palm Desert Middle School, Palm Desert, Riverside County

Overview

Objectives/Goals To see if a layer of canola oil on top of water can stop or at least slow down the process of evaporation so cities that have water evaporation issues can help preserve their water. Methods/Materials 6 wide mouth jars water canola oil ruler pencil paper measuring cup Results Jars D,E,and F with the oil on top had more water in them by about 2 inches at the end of 14 days than jars A,B, and C without any oil. Conclusions/Discussion In conclusion, my hypothesis proved correct. Jars D,E, and F had more water than jars A,B, and C at the end of 14 days, proving that the oil helped stop the evaporation process.

Summary statement

My project tests whether oil sitting on top of water affects the evaporation process.

Help received

Mother bought supplies and helped glue items on board.
