The hypothesis is that polyester will be the most water resistant fabric and that all fabrics will demonstrate better water resistance after a layer of Scotch Guard is applied.

You will cut the fabrics into the same size, measure their weight, treat some with Scotch Guard, spread them on a ramp, sprinkle water over them, and measure their weight again.

You will need a ramp, fabric pieces, Scotch tape, scissors, a ruler, tap water, a measuring cylinder, a plastic bottle with holes on the cover, and a digital weighing scale.

The results showed that nylon and wool were the most water resistant fabrics and polyester was the least. Treating fabrics with Scotch Guard made them more waterproof.

This science project is interesting because it tests different fabrics to see which ones are the most water resistant and how Scotch Guard affects the water resistance of the fabrics.

Consider repeating the experiment by immersing the fabric in water and comparing the time taken for them to dry, or by testing different types of fabrics.
