Before class begins, prepare five bags filled with about beads each. For each bag, count a specific number of "parent isotope" beads of one color and "daughter isotope" beads of another color. Once you have a set of parent and daughter isotope beads in the bag, fill up the bag with a mixture of all the other colors. Next, label each bag with a number , put it at a separate station around the room, and make a sign that identifies the parent isotope type and color, daughter isotope type and color, and half-life. For instance, your five bags might be set-up something like: The bag itself represents the fossil and the beads inside represent some of the millions of atoms that make it up.

Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus. A particular isotope of a particular element is called a nuclide.
New information needed to be introduced with parent and daughter isotopes. Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs. They will do this 8 times.
You will now complete several half-life simulations using the 16 pennies. Starting with all 16 pennies in a heads-up position, turn pennies over to tails to indicate decay of the element. Enter your observational data in the chart below as you go.
