1. Significance Testing
   1. Analysis of Human Population Growth
      This 3-part activity is designed to introduce students to human population growth. Several online sources are used in this activity, including a World Population Clock that is a real time data site. In Parts 1 and 2 students make a variety of mathematical calculations designed to illustrate the current size and growth rate of the human population. In Part 3 students analyze a graph that shows human population growth over time and complete a written assessment that requires them to demonstrate their level of understanding of population size, growth rate, factors that have led to current levels of growth, and predictions for the future.  The site includes three activities, rubrics for assessment, and suggestions for accomodations for special needs.
   2. Global Warming Statistics
      This site is a good resource for teachers and contains an activity for the students to collect data on the Internet about changing climates. The students then analyze the data with statistics as well as plot graphs and extrapolate.
   3. Put the Heart into Mathematics
      Outstanding! This NCTM (Illuminations) activity is geared for students in grades 9-12. This unit contains four different teacher lesson plans with reproducible student worksheets, and interactive graphing and data collection capabilities. The lessons provided explore cardiac output by measuring the amount of blood being pumped by an experimental heart. Students will explore rates of change and accumulation in the context of cardiac output and accumulation using hands on experimentation, data collection, "pencil and paper" activities, etc,.
   4. Shedding Light on the Subject: Function Models of Light Decay
      Presented by NCTM (Illuminations), this website provides the teacher with a four lesson unit on the decay of light as an exponential model. Teachers will appreciate the printer friendly lesson plans accompanied by student objectives, worksheets, and references. The site includes an interactive grapher and downloadable movie clips (quick time required) for students.
   5. What Percentage of your Class is Right or Left Handed?
      Cythia Lanius provides this lesson for high school students to determine the percentage of students that are right or left handed in a classroom. Students perform experiments, collect data, graph the data, and analyze their findings. Worksheets, spreadsheets and teacher notes are available.
