Show Notes
How do scientists work out how old things really are — when they’re way too old for birthday candles?
In this Squiz Kids Science Short, Christie explains how scientists date ancient objects, from tree rings and bones to buried cities, dinosaur fossils and rocks billions of years old. Discover how carbon dating works, why the ground keeps clues in layers, and how different scientific “clocks” help unlock the deep history of our planet.
