The first lesson, Isotopes of Pennies, deals with isotopes and atomic mass.

The second lesson, Radioactive Decay: A Sweet Simulation of Half-life, introduces the idea of half-life.

We will discover what a half life is and why it is important!

You may have heard of 'radioactive materials.' They can be dangerous, but many things are only a tiny bit radioactive.

Have you ever seen an ancient ruin and wondered how old it is?

In this lesson, you will learn about how scientists estimate the age of things when they are not sure using predictable decay rates.

Scientists perform a similar calculation when they are trying to find out how old things are.

The half-life of a substance is the amount of time that it takes for half of it to decay.
