Classroom Resources: Reactions & Stoichiometry

1 – 5 of 5 Classroom Resources

• 

  Heat, Temperature, Specific Heat, Law of Conservation of Energy, Enthalpy, Calorimetry, Exothermic & Endothermic, Balancing Equations, Chemical Change, Measurements, Mole Concept, Dimensional Analysis, Culminating Project, Interdisciplinary, Review, Graphing, Observations, Chemical Properties, Physical Properties | High School

  Project: Handwarmer Design Challenge

  In this project, students will use their knowledge of thermodynamics to design a handwarmer for a manufacturing company that can maintain a temperature of 30-40°C for at least 5 minutes and is designed for the average human hand. Students will create a final product after rounds of testing and an advertising poster that summarizes the results of their testing and promotes their design.

• 

  Heat of Combustion, Heat, Exothermic & Endothermic, Combustion | Elementary School, Middle School, High School

  Video: The Internal Combustion Engine Video

  This video investigates both the mechanical and the chemical processes used in the internal combustion engine, as well as the history and evolution of the combustion engine.

• 

  Balancing Equations, Precipitate, Solubility Rules | High School

  Animation: Net Ionic Equations Animation

  This animation explores what happens in a precipitate reaction on the particulate level. Students will see why writing a net ionic equation accurately represents what happens in these scenarios. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**

• 

  Limiting Reactant, Conservation of Mass, Stoichiometry, Mole Concept | High School

  Animation: Limiting Reactant Animation

  This animation 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. **This video has no audio**

  Reduction, Oxidation, Redox Reaction, Catalysts, Activation Energy, Combustion | Elementary School, Middle School, High School

  Video: Catalytic Converters Video

  This video investigates the role of a catalytic converter and its corresponding chemical reactions within a vehicle. Students will learn about both oxidation and reduction reactions and how they, in combination with a catalyst, can impact the molecules released in a car’s exhaust.
