Every part of your body is a material! Bone, muscles, fingernails, hair, and skin are all examples of different types of materials found in your body with remarkable properties that help you survive - from keeping you upright, and protecting you from heat or cold, to cutting and grinding your food. Some scientists try to mimic nature's designs to create materials for other uses, such as using the foam structure of bone as an inspiration for designing materials that are lightweight and strong.
