1) If lipstick is used often, then bacteria content on the surface area will be high.
2) -The dependent variable would the bacterial growth.
-The independent would ingredients in the lipsticks.
-The controlled variable would be the type of lipsticks.
3) My experiment addresses proper sanitation and cleanliness of cosmetics, which is a very significant factor when handling cosmetics. My EQ is all about technique and this experiment helps me with an important technique in the makeup industry. This experiment allows me to see how much bacteria is on ones face when different brands of makeup are neglected. Amounts of bacteria applied on one's face will cause harm to clients and will of course cause harm to your reputation; which is everything when becoming an accomplished make-up artist.
4) I will buy 5 different brands of rouge lipsticks and use each of them 20 separate times. Afterward i will properly analyses them. I will have to do a lot of research on bacteria and makeup ingredients. I will need to work with Ms. Mathews and Mr. Pang to see how to properly analyses the growth of bacteria in my cosmetics and the ingredients of makeup products. I do not have my entire experiment planned out in detail but her is a list of equipment I will most likely need:
- Journal
- Used cosmetic samples
- Microscope
- Computer
- Electrical outlet
- Writing utensil
- Data charts
- Examination Plates
- Containers
- Sanitized make-up spatula
- Hand Sanitizer
- 91% alcohol
5) Chemistry
