Salinity and Convection

Easy
Salinity and Convection | Science Fair Projects | STEM Projects
We'll investigate how salinity affects the rising and falling of water in a cycle. We'll use two containers, salt, food coloring, and liquid soap to observe the differences in the movement of the soap.

Hypothesis

The hypothesis is that salinity will affect the movement of water.

Method & Materials

You will place two containers side by side on hot plates, fill them with water, add salt to one container, add food coloring, and pour liquid soap into both containers.
You will need two large beakers or a heat-proof jar, food coloring, liquid soap, two hot plates, water, and salt.

Results

After observing the movement of the soap in both containers, it was found that the movement of the soap in the container with salt was more rapid.

Why do this project?

This science project is interesting because it allows us to observe the effects of salinity on the movement of water.

Also Consider

Variations of this experiment could include using different temperatures of water or different amounts of salt.
