§Independent Variable - The independent variables are the ultraviolet protective coatings, the type of material, and the color of the fabrics. This is because the absorption rate depends on the ultraviolet protective coatings, the type of material, and the color of the fabrics

§Dependant Variable – The dependant variable was the absorption rate, because the absorption rate of a fabrics depended on the variations applied to it.

§Control – In our experiment the control was the fabrics not coated with an ultraviolet protective additive. This is because it is well documented how everyday clothes absorb ultraviolet light.
