Imagine you’re a detective trying to solve a mystery. You need to figure out when a crime happened, and you have clues that can help you narrow down the timeline. Carbon dating is like a special tool scientists use to determine the age of ancient artifacts. It’s based on the fact that all living things contain a tiny amount of a radioactive form of carbon called carbon-14.
Carbon-14 is constantly being created in the Earth’s atmosphere. When plants take in carbon dioxide for photosynthesis, they also absorb carbon-14. Animals then eat those plants, incorporating carbon-14 into their bodies. This means all living things have a constant level of carbon-14.
But when an organism dies, it no longer takes in carbon-14. The carbon-14 in its body starts to decay at a predictable rate, with half of it disappearing every 5,730 years. This is known as the half-life of carbon-14.
By measuring the amount of carbon-14 remaining in an artifact, scientists can calculate how long ago the organism died. For example, if a piece of wood has half the amount of carbon-14 as a living tree, it means the wood is about 5,730 years old. If it has a quarter of the amount, it’s about 11,460 years old, and so on.
Carbon dating is a powerful tool that helps us understand the past. It allows scientists to date ancient bones, fossils, and even artifacts like mummies and tools. Carbon dating has revolutionized our understanding of history, archaeology, and the evolution of life on Earth.
