General Physics Science Fair Project

Temperature and Viscosity

Temperature and Viscosity | Science Fair Projects | STEM Projects
In this experiment, you'll measure the viscosity of water, milk, and corn oil at different temperatures to see how temperature affects the flow rate.


The hypothesis is that water has the lowest viscosity and the fastest rate of flow followed by milk, while corn oil has the highest viscosity.

Method & Materials

You will use an electric drill to make a small hole in a metal cup, fill the cup with the fluid, and measure the time it takes for the cup to empty.
You will need an electric drill, two metal cups, tap water, milk, corn oil, a hot plate, a thermometer, a stopwatch, and an assistant.


The experiment showed that water had the fastest rate of flow and the corn oil had the slowest. The flow rate of water, milk and corn oil increased as the temperature increased.

Why do this project?

This science project is interesting because it shows how temperature affects the viscosity of different fluids, which is important to understand when transporting fluids like water, crude oil, or natural gas through pipes.

Also Consider

Consider repeating the experiment using different fluids like honey, ethanol, and engine oil. Also, try repeating the experiment using a larger hole in the cup and observe if that makes any difference.
