  Activity: Animation Activity: Limiting Reactant Mark as Favorite (3 Favorites)

  In this activity, students will view an animation that explores what happens in a limiting reactant problem on the particulate level. 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.

  Lesson Plan: Clean Air Chemistry Mark as Favorite (19 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 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: Building a Nuclide Mark as Favorite (6 Favorites)

  In this activity, students will construct a model of a nuclide and use this model to investigate why the mass of the nuclide is less than the summative mass of the individual nucleons (protons and neutrons). Additionally, the constructed nuclide will be used to help students conceptualize and differentiate between key lesson terminology (mass defect, strong nuclear force, and nuclear binding energy).

  Demonstration: Understanding Limiting Reactants Mark as Favorite (42 Favorites)

  In this demonstration, the teacher will perform a series of reactions between acetic acid (vinegar) and varying amounts of sodium bicarbonate (baking soda) in order to inflate several balloons. Students will observe the reactions and analyze the quantities of reactants used as well as the results in order to understand the concept of limiting reactants.
