Minerals are made of tiny units called atoms. Atoms stick together in bonds. Each mineral is built from a slightly different pattern of bonds. Some minerals have more atoms than others. The atoms also form different shapes. Scientists have figured out how to replicate certain mineral bond patterns. They can create some minerals in a lab. This video shows different lab grown diamonds.
Humans need minerals to stay healthy. Minerals help parts of the body work properly. For example, calcium makes bones and teeth hard. It also helps muscles move correctly. Calcium is found in dairy products such as milk. People can also get calcium by eating green, leafy vegetables. Iron is a mineral found in blood. It helps carry nutrients to all parts of the body.
