  Lesson Plan: Vitamin C Quality Control

  In this lesson, students will learn about a career in the skilled technical workforce, develop skills utilized in a quality control lab, and obtain data that may not have a clear “right answer.” For example, though many over-the-counter medications and vitamins state the amount of active ingredient, any individual tablet may have between 97 to 103% of the stated label claim. In addition, any products past the expiry date may have less due to potential decomposition. Students practice scientific communication by reporting their findings in a professional manner.
