Understanding Carbon Dating: A Simple Guide

๐Ÿ•ฐ๏ธ What Is Carbon Dating?


๐ŸŒฟ What is carbon dating?

Carbon dating is a way scientists find out how old something is โ€” like:

  • Bones ๐Ÿฆด
  • Wood ๐ŸŒณ
  • Cloth ๐Ÿ‘•
  • Ancient tools ๐Ÿ—ฟ

๐Ÿ‘‰ It works only on things that were once alive.


โš›๏ธ What is carbon?

  • Carbon is an element found in all living things
  • There are different types of carbon
  • One special type is called Carbon-14

๐Ÿซ While livingโ€ฆ

  • Plants take in carbon from air ๐ŸŒฑ
  • Animals eat plants or other animals ๐Ÿ„
  • So all living things have Carbon-14 inside them

โšฐ๏ธ After deathโ€ฆ

  • When a plant or animal dies:
    • It stops taking in carbon
    • Carbon-14 slowly disappears (decays)

โณ This happens at a known speed


โฑ๏ธ How scientists tell the age

1๏ธโƒฃ Measure how much Carbon-14 is left
2๏ธโƒฃ Compare it with living things
3๏ธโƒฃ Calculate how long it has been decaying

๐Ÿ‘‰ Less Carbon-14 = older object


๐Ÿงฎ Important number (easy to remember)

  • Carbon-14 half-life = 5,730 years
  • Every 5,730 years, half of it disappears

๐Ÿ“ What carbon dating can and cannot do

โœ”๏ธ Can date:

  • Up to about 50,000 years old
  • Living things from the past

โŒ Cannot date:

  • Rocks โŒ
  • Metals โŒ
  • Very old dinosaurs โŒ (too old!)

๐ŸŒŸ Fun facts for kids

  • Used to date mummies
  • Used in archaeology
  • Helps learn human history

๐Ÿง  Easy way to remember

Carbon dating is like a natural clock inside living things


๐Ÿ“Œ One-line summary

Carbon dating finds the age of dead plants and animals by measuring how much Carbon-14 is left.
