Population growth can be simulated with a simple experience that tastes good. We will model

population growth as our first model and population decay as our second model. DO NOT EAT

the m&m's until we have finished the experiment. Try not to spill or drop the m&m's on the

floor. You will need about 50 m&m's to do this experiment.

Simulation of population growth:

Drop 1 m&m.

If it lands with the “m” up, add 1 m&m.

If it lands with the “m” down, do not add another, and repeat this step.

Drop 2 m&m’s.

Add 1 m&m for each m&m that lands with the “m” up.

Drop however many m&m’s you have.

Add 1 m&m for each m&m that lands with the “m” up, and continue repeating this step.

Keep track of the growth of m&m’s in the chart provided.

Decay

How long did it take your population to grow twice its size? 4 times its size? 8 times its size?
