Use your understanding of the scientific method to complete the following questions. A group of scientists is testing a new chemical to determine if it will act as a sunscreen and
prevent sunburn. The same amount of lotion is applied to each person in the same size area and
the test subject's arm is exposed to direct sunlight. The amount of redness is measured every 5
minutes for a total of 30 minutes.
For each person tested, 3 different lotions are applied to the test subject's arm:
1. a lotion with the new sunscreen chemical called Sun X
2. a lotion with a different active sunscreen chemical that has been successfully used for many years
called Sun Kissed
3. a lotion that has all the same ingredients as the sunscreens except it has no active sunscreen
chemical
