Title

What is Carbon Dating?

Reading Text

Everything that is alive has an element called carbon-14 in it. Plants, animals, and people all have carbon. When a living thing dies, the carbon stops entering its body. Slowly, the carbon starts to change and leave the object. This happens over a very long time. Scientists use 'carbon dating' to study old things. They measure how much carbon is left inside. This helps them find the age of the object. They can learn how old a bone, a piece of wood, or a shell is. It is like a specific clock for history. Carbon dating helps us understand the past.
