Exponential Decay Models

Today, we compared the exponential decay model with the exponential growth model. What we discovered is that the major difference in the formulae is that the growth factor is greater than one, while the decay factor is less than one. Students worked in groups to collect penny flipping data. Flipping pennies simulated what happens when radioactive atoms decay. Students flipped the pennies until they were able to eliminate all pennies from the flip pool.

Tonight's Homework: Graph the penny flipping data in a double line graph which includes a title, key, and labels. Please complete the following problems from the book: Lesson 8.5 ( 1 - 13 ) and Lesson 8.6 ( 1 - 13 ).
