• 

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

  Lab: The Lovely Lava Lamp Mark as Favorite (12 Favorites)

  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 Mark as Favorite (10 Favorites)

  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 Mark as Favorite (15 Favorites)

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

• 

  Balancing Equations, Limiting Reactant | High School

  Activity: S'more Stoichiometry Mark as Favorite (13 Favorites)

  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 Mark as Favorite (10 Favorites)

  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 Mark as Favorite (11 Favorites)

  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 Mark as Favorite (8 Favorites)

  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 Mark as Favorite (44 Favorites)

  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 Mark as Favorite (11 Favorites)

  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) Mark as Favorite (2 Favorites)

  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 Mark as Favorite (18 Favorites)

  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.
