This is a slide and worksheet for radioactive dating and half life activity.
The Slides are to be shown at the front and then each item is shown in turn and the pupils use their graphs to calculate the age of each item from the percentage of carbon found in them. take longer than you think, but keeps them engaged and there're questions to be answered in their books also.
The third is human-made, something created by humans that wouldn’t exist otherwise or something that contains more radiation in it than normal (enhanced) because humans have done something to it.

Radiation can be found in soils, in our air and water, and in us.
Because it occurs in our natural environment, we encounter it every day through the food we eat, the water we drink, and the air we breathe.
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.
Eventually, these substances change into different elements. For example, an isotope of uranium, U-238, will eventually decay into an isotope of lead.
