Radioactive dating practice worksheet

This lesson is designed to help students understand the concepts of radioactive dating to help determine the approximate age of fossils and rocks.After this lesson students will have an understanding of how materials undergo radioactive decay and that the rate of decay allows scientists to predict the approximate age of the specimen.The bag itself represents the fossil and the beads inside represent some of the millions of atoms that make it up.

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.

Find instructions for chemistry experiments and learn about chemical reactions, elements, and the periodic table in this collection.

Teachers can also find chemistry resources for the classroom.

A good idea is to have the graph printed on the worksheet with the data table so that the students can have it right in front of them.

Put on your lab goggles and start learning chemistry with these resources.

Each atom has a positively charged nucleus surrounded by negatively charged electrons.

The electric force between the nucleus and electrons holds the atom together.

The atom's nucleus is composed of protons and neutrons, which are much more massive than electrons.
