Carbon dating is a method used to figure out how old things are by looking at a special kind of carbon called carbon-14 that exists in all living things.
Here’s how it works:
1. Carbon-14 is in everything alive. Plants get carbon-14 from the air, and animals (including humans) get it from eating plants or other animals. So, while something is alive, it has carbon-14 in it.
2. When something dies, it stops getting carbon-14. After death, the carbon-14 in it slowly starts to disappear (it decays), but regular carbon (carbon-12) stays the same.
3. Carbon-14 decays at a known speed. Over time, carbon-14 breaks down at a steady rate. After about 5,730 years, half of the carbon-14 is gone. After another 5,730 years, half of what’s left disappears, and so on.
4. Scientists measure the amount of carbon-14 left. By measuring how much carbon-14 is still in a dead plant, animal, or human, scientists can figure out how long ago it died. If only half the carbon-14 is left, for example, the object is about 5,730 years old.
5. It’s like a clock. The less carbon-14 there is, the older the object. This method works for things that are up to about 50,000 years old.
So, carbon dating is a way of using the natural decay of carbon-14 to estimate the age of things that were once alive, like fossils or ancient artifacts.
