Evaporation Factors Science Fair Projects

Factor Projects

Many science fair projects are designed around factors that affect something else. When studying factors it is important to set up an experiment to test each factor separately.

Objectives/Goals

The objective was to see if wind, air temperature, humidity, surface area would effect evaporation in different ways.

Methods/Materials

For surface area, first measure 200 milliliters of water into a graduated cylinder. Second pour the water into a 8 by 8 container and 4 by 4 container. Thrid place containers in a box. Fourth record and observe containers every 15 minutes

For air temperature, first measure 200 milliliters into a graduated cylinder. Second put the 200 mililiters in a two 4 by 4 containers. Third place containers in the same box used for surface area. Fourth divide the box with a piece of cardboard. Fifth place heatlamp above 1 side of the box. Fifth record and observe containers every 15 minutes

For humidity, first change the box used from air temperature and surface area, cut one door in side, and seal that side with tape and plastic wrap. Second put one 4 by 4 container with 200 milliliters of tap water on each side of the divider. Third put containers in the box that was recently changed. Fourth put heat lamp above the box. Fifth record and observe containers every 15 minutes.

For wind, first measure 200 milliliters of tap water in a graduated cylinder. Second pour the water into 4 by 4 containers. Third place containers in the box used in humidity. Fourth place a fan across the container to blow on one side of the box. Fifth place heatlamp over the box. Sixth record and observe the containers

Results

Surface Area: The container with more surface area evaporated faster
Air Temperature: The container with more heat evaporated faster
Humidity: The one with more humidity evaporated faster
Wind: The container with wind blowing evaporated faster

Conclusions/Discussion

It shows that larger surface areas help water evaporate faster
More heat makes evaporation go faster
High humidity makes water evaporate slower
Wind helps evaporation go faster 3rd party contributor
