  1. The Colorimeter Probe And integrated math and science approach. Rachel, Melissa, Kerrie, Nathan, Matt, & Beth

  2. Absorbance and Concentration • Beer’s Law states that there is a linear relationship between the concentration of a solution and its absorbance. • A = epsilon * b * C, b = width of cuvette

  3. Our Experiment • We used different amounts of food coloring in water and measured each solution’s absorbance using the colorimeter. • The following slide is the somewhat linear graph we got from our experiment. It’s not exact because of experimental error.

  4. The Math of It • Students will discover whether or not this graph is linear, why it is linear, and how it relates to Beer’s Law and the equation y = mx + b. • We could also find the line of best fit and discuss how to find that on a given graph. • This is most appropriate for an Algebra II class.

  5. Science! • Students will make the different concentrations of solutions for their samples (in moles/liter). This gives them practice in making solutions. • This would best fit in an intro. or upper level chemistry class.

  6. Math, Science, and Inquiry • We would encourage students to inquire about other data they could collect, such as using different colors. • The students could be asked to explore more options that they come up with on their own.
