Heat (Thermodynamics) Science Fair Project

Temperature and Water Movement

Temperature and Water Movement | Science Fair Projects | STEM Projects
Have you ever wondered how temperature affects the movement of water? In this experiment, you will explore how temperature affects the movement of water by observing the movement of food coloring in jars of water with hot and cold water.


The hypothesis is that temperature affects the movement of water.

Method & Materials

You will fill three jars with water of different temperatures, add food coloring to each jar, and observe what happens to the food coloring.
You will need three heat-proof jars, food coloring, and water.


The results of the experiment showed that the food coloring moved differently in the jars of water with different temperatures. In the jar of hot water, the food coloring moved quickly to the top, while in the jar of cold water, the food coloring moved slowly to the bottom.

Why do this project?

This science project is interesting because it allows students to observe the effects of temperature on the movement of water in a simple and fun way.

Also Consider

Variations of this experiment could include testing the effects of salinity on the movement of water or testing the effects of different temperatures on the movement of oil.
