Lesson Plan: Vitamin C Quality Control Mark as Favorite (11 Favorites)
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 overthecounter 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.

Lesson Plan: Clean Air Chemistry Mark as Favorite (18 Favorites)
In this lesson, students will learn about air pollution and some steps toward mitigating it. First, they will burn a candle and measure its mass and the concentration of CO2 over time. Students will discuss which data set they have more confidence in and why and then use stoichiometry to predict outcomes. Next, students explore incomplete combustion in a modelbased worksheet that shows how a lack of O2 in the burning of fuels can produce air pollution. Students work together to interpret the models, define terms, and draw conclusions. Lastly, students work in groups using Lego models to illustrate how a catalytic converter works. They race “Nature” against catalysts “Palladium,” “Platinum,” and “Rhodium” to see what breaks down air pollution molecules fastest.
