Carbon dating half life worksheet
Or, just print the graph for all pupils to use independently....
This is why it is such a big concern when a nuclear submarine sinks... (By the way, you are mostly Carbon-12, which is not radioactive.
It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old.
Carbon has two stable, nonradioactive isotopes: carbon-12 (12C) and carbon-13 (13C).
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.

This is a slide and worksheet for radioactive dating and half life activity.
Scientists now know that most elements come in more than one version. When the dry periods ended and the water level rose, the trees drowned, marking the end of the droughts.There are also trace amounts of the unstable radioisotope carbon-14 (14C) on Earth.Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.The amount of carbon-12 stays the same, but the carbon-14 decays away, at a constant rate, making carbon-14 a ticking atomic clock.If you're seeing this message, it means we're having trouble loading external resources on our website.
