Half Life Lab

Introduction
The discovery of radioactivity in the late 1800’s allowed scientists to develop new methods of determining the absolute age of rocks. Since it is not safe for us to play with radioactive isotopes, we will use pennies to simulate radioactive decay. The plastic box in this lab represents an imaginary rock.

Suppose that 100 heads-up pennies in your box represent atoms of an imaginary radioactive element called Headsium. When Headsium “decays”, it becomes a different imaginary element called Tailsium, which is stable (non-radioactive). After you shake the box for 15 seconds, approximately half of the pennies will have decayed (flipped over) to stable Tailsium. Thus 15 seconds is the half-life for Headsium.
1

Prepare a graph by plotting the number of half-lives on the X-axis and the number of radioactive Headsium on the Y-axis.

1

Describe the appearance of your line. Is it straight or curved?

1
How many undecayed Headsium atoms would remain in a sample of 600 pennies after 3 half-lives? _______
1
If 175 Headsium atom are left out of a sample of 2800, how many half-lives would have passed? _______
1

I am going to give you $1,000 (DREAM ON!) but you must spend ½ of it in the first year, ½ of the balance in the second year, etc. One year represents one half-life of the $1,000.

1
If you spend the maximum allowed each year, at the end of what year will you have $31.25 left? _______
1
How much money would be left after 10 half-lives? _______
