Today I am working on research about the science behind makeup! Here is what I found so far. It talks about how to make a scab and how a real scab forms!

Sci Fi: Science in Films: Family Take Home Activity Movie Makeup: Bloody Scabs
Objective: You will make a realistic bloody scab.
Materials: Red food coloring, cocoa powder, petroleum jelly, tissue
FCAT Vocab: Circulatory system - a body system that transports nutrients, blood, hormones and other essentials throughout the body to maintain homeostasis.
Procedure:

1. Start with a teaspoon of petroleum jelly.
   
2. Add a pinch of cocoa powder and a few drops of red food coloring.
   
3. Dab half of the mixture onto desired scab area (keep away from eyes).
   
4. Crumple up about 2 square inches of tissue and squish into scab.
   
5. Add the rest of the jelly mixture, as desired.
   
6. Sprinkle some cocoa powder to make it look crusty and/or add a few drops of
   food coloring to make dripping blood.
   

Now you can experiment with different techniques to meet your specific scab needs. Try to make it dry or look like a gash, or make it look like a bite mark!
Discussion:
What body system does your blood pump through?
Your body pumps blood through the circulatory system, a system that maintains homeostasis. Thecirculatorysystemcontainsthecardiovascularsystem,which transports blood throughout the body, and the lymphatic system.
What are some major organs in your circulatory system? Thecardiovascularsystemincludestheheartandbloodvessels. Thelymphaticsystem contains the conducting system and lymphoid tissue.
How are scabs formed?
When your body gets a cut, glue-like platelets rush to the scene to stop other liquid from flowing out. As it starts to dry, it forms a scab on the outside, while underneath new skin forms until the scab falls off.
