Subject: Mathematics (9 - 12)
Title: Exponential Growth and Decay
Description: This lesson on exponential growth and decay involves a variety of teaching resources. There are a variety of websites used to teach and reinforce how to identify exponential growth or decay and how to solve problems relating to growth and decay. There is a lab provided that will help model these concepts being taught and computer based practice on these concepts. Videos are provided that give a picture image of how exponential growth and decay works. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Title: Radioactive Decay: A Sweet Simulation of Half-Life     
Description: In this Science NetLinks lesson, the second lesson in a three-part series about isotopes, radioactive decay, and the nucleus, students are asked to simulate radioactive decay by pouring small candies and counting which candies fall with their manufacturer's mark down or up. The exercise they go through of predicting and successively counting the number of remaining '' mark-side up'' candies should help them understand that rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.

Title: Shedding the Light     
Description: In this four-lesson unit, from Illuminations, students investigate a mathematical model for the decay of light passing through water. The goal of this investigation is a rich exploration of exponential models in context. Students examine the way light changes as water depth increases, conduct experiments, explore related algebraic functions using an interactive Java applet and analyze the data collected.
