Classroom Resources: Reactions & Stoichiometry

26 – 36 of 36 Classroom Resources

• 

  Density, Observations, Chemical Change, Physical Change, Balancing Equations | High School

  Lab: The Lovely Lava Lamp

  In this lab, students add food coloring to a mixture of oil and water and record their observations. They then add an Alka-Seltzer tablet, record their observations and answer a series of questions about the chemical and physical changes that took place.

• 

  Limiting Reactant, Stoichiometry, Balancing Equations, Mole Concept, Dimensional Analysis | High School

  Activity: Sweet Stoichiometry Reactions

  In this activity, students will use candy to investigate stoichiometry and mole-gram relationships in chemical equations, but could also be used to introduce the concept of limiting reactants.

• 

  Balancing Equations | High School, Middle School

  Activity: Snowman Challenge

  In this activity, students practice completing and balancing chemical equations with a partner.

• 

  Balancing Equations, Limiting Reactant | High School

  Activity: S'more Stoichiometry

  In this activity, students determine the number of graham crackers and chocolate pieces required to complete a “reaction” with a given quantity of marshmallows (the limiting reactant). They then use the same thought process with a problem involving a real chemical reaction.

• 

  Limiting Reactant, Concentration, Net Ionic Equation, Stoichiometry, Balancing Equations, Precipitate, Mole Concept, Dimensional Analysis | High School

  Lab: Finding CO₂ Mass in your Breath

  In this lab, students will measure how much carbon dioxide they exhale by reacting their exhaled breath with lime water (calcium hydroxide).

• 

  Precipitate, Chemistry Basics, Solubility Rules, Balancing Equations, Chemical Change, Chemical Change | High School, Middle School

  Lab: Predicting Precipitates

  In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.

• 

  Electrolysis, Cathode, Anode, Half Reactions, Redox Reaction, Reduction, Oxidation, Electron Transfer, Balancing Equations, Exothermic & Endothermic | High School

  Lab: Electrolysis of Water

  In this lab, students will perform the electrolysis of water using a battery, test tubes, thumbtacks, and a plastic cup.

• 

  Classification of Reactions, Balancing Equations, Chemical Change, Conservation of Mass, Observations | High School

  Lab: Classifying Reaction Types

  In this lesson, students will carry out various reactions and classify the reaction types.

• 

  Balancing Equations, Chemical Change, Observations | High School, Middle School

  Lab: Chemical Reactions & Equations

  In this lesson, students will observe a series of reactions, make observations, and then write balanced chemical equations to chemically describe what they observed.

• 

  Chemical Change, Combustion, Balancing Equations | High School

  Demonstration: Methane Bubble (Dragon Ball Z)

  In this demonstration, students will observe the combustion of methane using hands-on practices.

• 

  Balancing Equations, Conservation of Mass | Middle School, High School

  Activity: Simulation Activity: Balancing Chemical Equations

  In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
