Modeling Isotopes
Some pennies are
made of copper.

Modeling Isotopes
Some are made of zinc.

Modeling Isotopes
There was also one year when they were made from steel.
These are rare. We probably won’t see any of these today.

Modeling Isotopes
The change from copper
to zinc happened in 1982.

Modeling Isotopes
Pre- and post-1982 pennies can be used to model an element with two naturally occurring isotopes.

Modeling Isotopes
There are three parts to this lab.

Modeling Isotopes
There are three parts to this lab.
1.Find the average mass of a copper penny and of a zinc penny.

Modeling Isotopes
There are three parts to this lab.
2. Use mass × abundance to find an “atomic mass” for your sample of pennies.

Then trade samples
with another group!

Modeling Isotopes
There are three parts to this lab.
3. Use “atomic mass” to predict the abundance of zinc and copper pennies in your new sample.

At the end, compare your predictions with
the other group’s measurements.
