Modeling Exponential Growth and Decay

Students participated in a set of activities to model radioactive decay and exponential growth. First, students flipped pennies and class data was collected. Those who flipped a head remained in the game, while those flipping a tail where out for the rest of the game. We did this three times to get a complete set of class data. Next we looked at bacterial growth related to the culturing of bacteria causing strep throat.

Tonight's Homework: Make a graph of the penny flipping data. Find a rule that includes an exponent to describe the data. Then make a graph of the bacterial growth data. Again, try to find a rule that includes an exponent to describe the data.
