Determine the effectiveness of a sunscreen product by measuring the extinction coefficient of its active ingredients.
The compound melanin is produced in skin cells and absorbs strongly in the UV region. Melanin pigments your skin, resulting in darker skin after extended exposure to sunlight. The sunscreen industry markets its products with SPF (Sun Protection Factor) ratings. We can test the various SPF ratings by measuring their absorbance and use UV sensitive materials to see the effectiveness of different sun

Determining the effectiveness of different sunscreen products in blocking ultraviolet (UV) radiation
Are sunscreen lotions with higher SPF (sun protection factor) values necessarily more effective? They certainly cost more! Is there a co-relation between cost and effectiveness? The objective of this science fair project is to determine the effectiveness of various sunscreen products, by comparing their SPF values values The amount of UV radiation that is blocked, will be measured through the use

Effectiveness of Sunscreens Against Ultra Violet Light Experiment
With enough exposure Ultra Violet (UV) light is lethal to bacteria. Ultra violet light may also cause damage to human skin cells. It is thought this damage may destroy the ability of the skin cells to control cell division, thus leading to a type of skin cancer call melanoma.

The Effect of Shampoos on the Tensile Strength of Hair
The purpose of this experiment was to determine how various shampoos affect the tensile strength of human hair. The information gained from this experiment will help people know which shampoo will make their hair stronger so it won’t break off easily. Consumers will also know which brand to buy so that their hair is stronger and healthier. I think that this will be very beneficial for the ha
