Evaporation: What Affects the Rate?

Easy
Evaporation: What Affects the Rate? | Science Fair Projects | STEM Projects
Have you ever noticed that water evaporates faster in some places than others? In this project, you'll explore what affects the rate of evaporation of water.

Hypothesis

The hypothesis is that evaporation of water will happen faster given a higher surface area, higher temperature and lower air pressure environment.

Method & Materials

You will observe the rate of evaporation of water in different environments, such as with different surface areas, temperatures and air pressures.
You will need 5 plates that can hold 100ml water, 1 glass that can hold 100ml water, 600 ml water and 1 fan.

Results

The results of the experiment showed that the plate with the larger surface area, the plate placed under the sun and the plate placed under the fan had the water evaporating faster. This proves that the hypothesis is true - evaporation of water will happen faster given a higher surface area, higher temperature and lower air pressure environment.

Why do this project?

This science project is interesting because it explores the water cycle and how different environmental factors can affect the rate of evaporation.

Also Consider

Experiment variations could include repeating the experiment using oil, alcohol and other liquids to compare the rate of evaporation.
