The skin model you will use will be JELL-O® in petri dishes. JELL-O is a gelatin
dessert mostly made from water and gelatin, which is a substance derived from
collagen. Collagen is a group of fibrous proteins found in many tissues in humans and other
animals, where it helps connect and support tissues. It is commonly found in the skin and is
particularly important in the dermis layer. While this gelatin dessert will be used as a model
for human skin in this science project, it is clearly different from human skin. As with any
model, keep in mind how your model is different from the real thing (i.e., human skin).
