I want to do a science fair project on which skin moisturizer works best. How can I find some ideas on ways to test this? Thank you!
you could collect differrent types of skin moisturizers, and cover them. Then, ask test subjects to use them, each person not knowing which mouisterizer is which, and ask them to write down how they feel after using the mouisterizers. Or, you could test them on yourself.
Try some of the following links for more ideas:
