Classroom Resources: Reactions & Stoichiometry
26 – 42 of 42 Classroom Resources
-
Conservation of Mass, Balancing Equations, Limiting Reactant, Introduction, Conservation of Mass | Middle School, High School
Activity: Kinesthetic Reactions
In this lesson students, through their physical movement, will model the law of conservation of mass during a chemical reaction. Students will also explore the concepts of limiting and excess reactants as well as balancing a chemical equation. Through this activity they also develop a means of representing particles at the molecular level.
-
Chemical Change, Classification of Reactions, Balancing Equations | High School
Lab: It's Time to React
In this lab, students will conduct four chemical reactions and analyze each for indicators of a chemical reaction. Based on their observations students will write a balanced chemical equation for each reaction as well as identify the reaction type for each reaction.
-
Net Ionic Equation, Chemical Change, Solubility Rules, Solubility, Precipitate, Balancing Equations, Chemical Change | High School
Lab: Ions in Aqueous Solution Presentation
In this lab, students will mix ionic solutions to determine what combinations form precipitates.
-
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.
-
Photosynthesis, Conservation of Mass, Balancing Equations, Chemical Change, Reversible Reactions, Molecular Formula, Interdisciplinary, Chemical Change, Conservation of Mass | Middle School
Lesson Plan: The Building Blocks of Photosynthesis
In this lesson, students will use colored blocks to represent the elements in photosynthesis and illustrate how they are broken down and reassembled to create glucose.
-
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.
-
Conservation of Matter, Chemical Change, Photosynthesis, Balancing Equations, Reversible Reactions, Molecular Formula, Molecular Structure, Conservation of Mass, Interdisciplinary, Matter, Elements, Monomer | Elementary School
Lesson Plan: Plant Chemistry
In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.
-

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.
-
Balancing Equations, Conservation of Mass
Simulation: Balancing Chemical Equations
The simulation for the September 2014 issue comes from PhET and helps students practice balancing chemical equations. AACT helped fund the conversion of this popular simulation into a format that is compatible with all devices, including iPads. PhET provides teacher’s guides for many of their simulations, and teacher-generated activities that can accompany the simulations.
