Testing the Strength of Water Surface Tension

Easy
Testing the Strength of Water Surface Tension | Science Fair Projects | STEM Projects
Have you ever wondered how strong water can be? Test the surface tension of water by adding salt and increasing the temperature to find out how much weight it can hold.

Hypothesis

The hypothesis is that when salt is added to water and the temperature of the water increased, the surface tension of water is reduced.

Method & Materials

You will measure the surface tension of water by adding salt and increasing the temperature.
You will need a container of water, salt, a thermometer, and a weight.

Results

The experiment showed that the surface tension of water can be reduced by adding salt and increasing the temperature. The most interesting observation was that the surface tension of the water was able to hold up a weight.

Why do this project?

This science project is interesting because it shows how the surface tension of water can be manipulated to hold up a weight.

Also Consider

Variations to consider include testing different amounts of salt and different temperatures.
