Keeping Warm with Fabric

Keeping Warm with Fabric | Science Fair Projects | STEM Projects
In this experiment, you'll compare the insulating properties of different fabrics by measuring the temperature of water in flasks. You'll use Thinsulate fabric, cotton fleece, and air to see which one keeps the water warm the longest.


The hypothesis is that Thinsulate fabric retains heat and keeps water in a flask warm for the longest period of time.

Method & Materials

You will use 3 conical flasks, 3 corks, an electric drill, 3 thermometers, a scarf made from Thinsulate fabric, a scarf made from cotton fleece, 2 strings, tap water, a hot plate, and a clock.
You will need 3 conical flasks, 3 corks, an electric drill with the bits, 3 thermometers, 1 scarf made from Thinsulate fabric, 1 scarf made from cotton fleece, 2 strings, tap water, 1 hot plate, and 1 clock.


The experiment showed that the water in the conical flask wrapped with Thinsulate fiber remained warm the longest, followed by the flask wrapped with the cotton fleece scarf.

Why do this project?

This science project is interesting because it shows how different fabrics can be used to keep us warm in different climates.

Also Consider

Experiment variations to consider include repeating the experiment using different materials like fur, wool, silk and leather, or increasing the layers of fabric and comparing the results.
