  Review, Culminating Project, Stoichiometry | High School

  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.

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.

  Activity: Ingenious: Making Shipping Greener with Hairy Ships Video Questions

  In this activity, students will answer questions while watching the video, Making Shipping Greener with Hairy Ships, from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the “fouling” of boats (when aquatic animals like barnacles and tubeworms attach to hulls), and the impact it has on fuel efficiency. Since fouling is a significant contributor to the carbon footprint, this video highlights how scientists were inspired by unique aquatic plants to develop a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

  Video: Ingenious Video 5: Making Shipping Greener with Hairy Ships

  The “fouling” of boats — when aquatic animals like barnacles and tubeworms attach to hulls — has been a nuisance for as long as we’ve been sailing the seas. Fouling messes up a vessel’s streamlined shape, decreasing its speed, maneuverability, and in modern times, its fuel-efficiency. Fouling spikes the carbon footprint of the shipping industry, already greater than that of most countries. For centuries, people used copper coatings to prevent fouling. Modern solutions use toxic chemical paints that pollute the water, kill marine life, and contribute to the degradation of our oceans when they wear off. A new approach is trying to work with nature instead of against it. Taking inspiration from the Salvinia plant, which is covered in tiny hair-like structures that make it basically waterproof, scientists are developing a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

  Molecular Structure, Catalysts | High School

  Video: Ingenious Video 1: The Strange Chemistry Behind Why You Get Sick on Planes

  The compound ozone, a known respiratory irritant, exists in high concentrations at flight altitudes, making the “fresh air” sucked in by air conditioners at those heights, well, not so fresh. In fact ozone exposure may be responsible for many of the short-term discomforts we associate with air travel. What’s more, ozone can react with other compounds in the air -- even the oils of our skin -- to produce other toxic compounds, like aldehydes and ketones. Some planes have catalytic converters, like the ones in cars, which use transition metals to turn ozone into breathable oxygen. But not every plane has one!
