    This lesson does a great job of explaining doubling time and half-life and showing how to find / use these values in real-world situations. The topics are explained very well, and all steps involved in solving the 2 problems presented using a TI graphing calculator are very clear. Solving by hand using paper is also shown in this lesson.
