Procedure:

Place the M&Ms in a cup or bowl.

Toss (but not too vigorously) the M&Ms on a clean flat surface.

Count the number of M&Ms in total - this is your number of radioactive material at time zero.

Then count the number of M&Ms with the 'M' side up, these are the ones that have NOT decayed. The remaining M&Ms are the nuclei that have decayed and may be removed/eaten.

Record these numbers in a table with number of throws and number of radioactive nuclei.

Continue this method with only the M&Ms that had landed M side up until no more M&Ms are left (or they have all decayed)

Make a prediction for the half-life for the M&Ms and how did you come to this decision?

Record your data or use the table below.

Number of Throws	Number of undecayed nuclei
0	195
1	98
2	55
3	27
4	14
5	8
6	3
7	1
8	1
9	1
10	0

Graph data of nuclei vs tosses.

What is the half-life for the M&Ms?
