Carolina Investigations® for AP® Chemistry: Spectrophotometric Analysis of Food Dyes Kit

Item # 840568 Exclusive

A Carolina Exclusive! Addresses AP® Chemistry Big Idea 1 and Learning Objective 1.16. Determine the concentration of food dyes in powdered drink mixes using Beer-Lambert’s law. Prepare standard solutions of 2 food dyes, plot calibration curves of absorbance as a function of concentration for each dye, and determine the concentration of each dye in its unknown solution. Procedure does not use toxic thiocyanate salts. For 30 students working in teams of 3.

  • Aligned with Big Idea 1 and Learning Objective 1.16
  • Emphasizes Science Practices 1, 2, 3, 4, 5, 6, and 7

Determine the concentration of food dyes in powdered drink mixes using Beer-Lambert's law. Teach this laboratory experience using either the guided activity or inquiry activity. In the guided activity, students prepare solutions of known concentration for each of 2 food dyes, measure each solution's absorbance, and graph a calibration curve for each food dye. Students then use their data and curve to determine the concentration of food dye in unknown solutions containing a single food dye.

The inquiry activity allows students to design a procedure to determine the concentration of each food dye in its unknown solution. Students must choose the concentrations of the standard solutions that will allow them to interpolate the concentration of food dye in the drink mix and prepare the solutions. It also provides opportunity for students to present their experiment's design and results, reinforcing the practice of communicating findings. Detailed preparation and procedure notes guide you through leading a successful inquiry exercise, including a suggested rubric for assessing student performance.

Both activities include Big Idea assessment questions that follow the AP® Chemistry Exam free-response question format. In the Big Idea assessment, students are given absorbance data for a complex ion, asked to identify the wavelength of maximum absorbance, plot provided data to generate a calibration curve, and determine the concentration of the complex ion.

This kit provides the following AP® Chemistry experiences: design a procedure to collect data; analyze data; perform error analysis; plot calibration curves, and interpolate data from the curves. Because the experiment uses food dyes rather than thiocyanate salts, it is safer and generates no hazardous waste. Materials are sufficient for 30 students working in teams of 3. Digital teacher’s manual, included FREE with kit purchase, is a 12-month eBook license to the Spectrophotometric Analysis of Food Dyes teacher’s manual. You can also access the digital student guide for this kit for free at Carolina Science Online®.

Carolina Investigations® for AP® Chemistry: Kits That Support the AP® Curriculum

Carolina Investigations® for AP* Chemistry Kits

If you are an AP® teacher, you go out of your way to help your students perform successfully on the AP® Exam. Carolina Investigations® for AP® Chemistry Kits are specifically designed to help you do just that.

Carolina Investigations® for AP® Chemistry kits are specifically designed to meet the goals of the revised AP® Chemistry curriculum. That curriculum and our kit series center on 6 overarching BIG ideas, which provide the themes for an enhanced laboratory experience focused on inquiry-based, student-directed learning:

  • Big Idea 1: Atoms
  • Big Idea 2: Chemical and Physical Properties
  • Big Idea 3: Changes in Matter
  • Big Idea 4: Rates of Chemical Reactions
  • Big Idea 5: Thermodynamics
  • Big Idea 6: Chemical Equilibrium

The AP® Chemistry curriculum emphasizes science practices, which allow students to use the tools of scientists to discover, test, and explain natural phenomena. The science practices of AP® Chemistry are integrated into each lab in the Carolina Investigations® for AP® Chemistry series.

  • Science Practice 1: Modeling
  • Science Practice 2: Math
  • Science Practice 3: Scientific Questioning
  • Science Practice 4: Data Collection
  • Science Practice 5: Data Analysis
  • Science Practice 6: Using Scientific Explanations and Theories
  • Science Practice 7: Connecting Concepts

All Carolina Investigations® for AP® Chemistry kits offer:

  • Two teaching approaches: a guided activity and an inquiry activity
  • Big Idea assessment questions modeled on the AP® Chemistry Exam’s free-response questions
  • Detailed inquiry activity preparation and procedure steps
  • Inquiry activity experimental design template based on the scientific method
  • Inquiry activity grading rubric

Carolina Investigations® for AP® Chemistry kits are designed to help AP® teachers help their students achieve exceptional results by:

  • Facilitating the successful integration of inquiry-based learning into the laboratory experience
  • Using teacher-developed and field-tested activities that are designed for the AP® classroom
  • Cultivating students’ conceptual understanding of the topics covered, while allowing them to draw upon real-world connections
  • Mirroring the free-response section of the AP® Exam using assessment questions focused on the Big Ideas
  • Integrating mathematics and analytical thinking through the graphing and interpretation of student-collected data
  • Reinforcing knowledge by connecting concepts to students’ lives
  • Minimizing teacher prep and cleanup time
