Today, I had more chemistry. We did an activity today called Half-life Simulation.
Materials:

• 100 Pennies
• Shoebox
• Graph paper

Instructions:

1. Put the 100 pennies into the shoebox
2. Make sure that they are all heads up.
3. Close the shoebox.
4. Shake the box vigorously.
5. Open the box
6. Count how many pennies are tails up in the shoebox
7. Record your data
8. Remove the tails-up pennies
9. Close the box
10. Repeat steps 4 through 9 four times
11. Use the data to plot a graph
12. Use the class total to plot a graph

This activity is supposed to demonstrate half-life.
