Lab: The Gravimetric Analysis of Lead in Contaminated Water
In this lab, students will perform a gravimetric analysis of a simulated water sample contaminated with “lead”. Using their knowledge of solubility and chemical reactions they will precipitate the “lead” from the water sample. Then from the data collected, they will calculate the concentration of “lead” in their samples and compare that value to those found in water samples from the Flint, Michigan water crisis.

Activity: The Chemistry Escape Room Remix
In this activity, students will apply their chemistry knowledge in order to solve ten clues in an effort to determine a three-digit combination that will open a “lock.” This is ideal for a review activity, as the clues span a plethora of chemistry topics. The solution from each clue will be used to correctly write a chemical reaction and a corresponding stoichiometry calculation. Ultimately, by solving the stoichiometry calculation, the answer will match the numbers in the three-digit combination and open the “lock.”

Lesson Plan: Clean Air Chemistry
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 model-based 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.

Activity: Animation Activity: Limiting Reactant
In this activity, students will use an animation to visualize on the particulate level what happens in a limiting reactant problem. Assembling a bike is used as an analogy to introduce the concept of limiting reactant, and then the balanced equation of the combustion of methane is used in four quantitative examples to show what it means for a chemical to be a limiting reactant. The concept of the conservation of mass is also demonstrated by calculating masses from the mole quantities of the reactants and products.

This engaging activity is not only fun for all students but also allows for interactive and collaborative review.
