The hypothesis is that of the five types of fabric, wool has the greatest heat-retention properties.

You will use conical flasks, corks, an electric drill, thermometers, a cotton scarf, a flannel scarf, a polyester scarf, a woolen scarf, a Gore-Tex jacket, a hot plate, tap water, a measuring cylinder, and a clock.

You will need 6 conical flasks, 6 corks, an electric drill, 6 thermometers, a cotton scarf, a flannel scarf, a polyester scarf, a woolen scarf, a Gore-Tex jacket, a hot plate, tap water, a measuring cylinder, and a clock.

The results showed that Gore-Tex kept the water in the flask warm for the longest period of time, while the water in the flask wrapped with polyester was the first to turn cold. The hypothesis does not hold true: among the fabrics, wool did not keep the water in the flask warm for the longest period of time.

This science project is interesting because it explores the thermal insulation properties of different clothing materials, which is important for people who live in countries with four seasons.

Consider using other materials such as fur, silk and leather. Also, try using thicker clothes and compare the results.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
