 Modeling Exponential Growth This lesson plan from ATEEC will help students learn the concept of exponential growth, as well as interpret and apply exponential relationships. It is intended for environmental science or biology classes. The activity sheet includes a list of materials and resources needed as well as a description of the lesson. This resource is free to download from ATEEC; users must create a free login to... http://ateec.org/modeling-exponential-growth
 Math Videos Captioned and Signed in ASL: Introduction to Exponents This is a video on exponents in the series of lessons on math provided by DeafTEC. Gary Blatto-Vallee, a math and science instructor at the National Technical Institute for the Deaf, guides viewers through a variety of mathematical exercises in this DeafTEC video series. All lessons are fully captioned, signed in ASL, and voiced. In this 9:38 video, Blatto-Vallee uses an electronic whiteboard to... https://deaftec.org/resources/math/self-instruction/introduc...
 National Debt and Wars This algebra lesson from Illuminations has students collect data about the national debt, and then plot that data by decade. They will then determine whether an exponential curve is a good fit for the data. The interdisciplinary learning unit compares the national debt during the Civil War, World War I and World War II. The material is appropriate for grades 9-12 and should require 2 class... http://illuminations.nctm.org/Lesson.aspx?id=2272
 Modeling Orbital Debris Problems This algebra lesson from Illuminations helps students develop their understanding of mathematical functions and modeling using spreadsheets, graphing calculators, and computer graphing utilities. The differences between linear, quadratic and exponential models are described. Students will also improve their understanding of how to choose the appropriate graphical representations for data. The... http://illuminations.nctm.org/Lesson.aspx?id=1386
 Drug Filtering This lesson from Illuminations looks at exponential decay. The example of how kidneys filter blood is used. The material asks students to determine the amount of a drug that remains in the body over a period of time. Students will predict behavior by an exponential decay model and graph an exponential set of data. The lesson is appropriate for grades 9-12 and should require 1 class period to... http://illuminations.nctm.org/Lesson.aspx?id=3081
