This hands-on activity is a simulation of some of the radiometric dating techniques used by scientists to determine the age of a mineral or fossil.
The activity uses the basic principle of radioactive half-life, and is a good follow-up lesson after the students have learned about half-life properties.
In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
They are also found in fossils and remains of organisms.
Absolute-age dating is way for scientists to tell the exact age of a rock, fossil, or other object. Isotopes are atoms of the same element that have the same chemical properties. These isotopes are found in igneous and metamorphic rocks.
This process involves measuring the rate of decay of radioactive isotopes.
When we look at sand in an hourglass, we can estimate how much time has passed based on the amount of sand that has fallen to the bottom.
