51 – 61 of 61 Classroom Resources

  • Balancing Equations, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis, Measurements | 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.

  • Balancing Equations, Predicting Products | High School, Middle School

    Activity: Snowman Challenge

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

  • Solubility, Chemical Change, Precipitate, Net Ionic Equation, Balancing Equations, Chemical Change, Solubility Rules | High School

    Lab: Ions in Aqueous Solution Presentation

    In this lab, students will mix ionic solutions to determine what combinations form precipitates.

  • Concentration, Molarity, Balancing Equations, Stoichiometry, Mole Concept, Dimensional Analysis, Saturated/Unsaturated/Supersaturated | High School

    Lab: Kool-Aid

    In this lab, students calculate grams of Kool-Aid powder required to make 3 different solutions of Kool-Aid (using the molar mass of sugar) with the following concentrations: 0.2 M, 0.5 M, and 1.0 M. Determine the concentration of properly prepared Kool-Aid through a taste test.

  • Chemical Change, Reaction Rate, Catalysts, Balancing Equations, Percent Yield, Stoichiometry, Chemical Change, Dimensional Analysis, Measurements, Scientific Method, Error Analysis, Experimental Design, Error Analysis | High School

    Lesson Plan: Catalysis & Catalytic Converters

    In this lesson students will be introduced to catalysts while expanding their knowledge of chemical reactions and stoichiometry. They will first learn about catalytic converters and then be challenged to create the best “catalytic converter” of hydrogen peroxide to oxygen gas in an inquiry-based activity.

  • Observations, Density, Chemical Change, Physical Change, Balancing Equations, Chemical Change, Physical Change, Mixtures | 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.

  • Observations, Separating Mixtures, Physical Properties, Intermolecular Forces, Polarity, Distillation, Cracking, Balancing Equations, Intermolecular Forces, Boiling Point | High School

    Lesson Plan: Fractional Distillation of Crude Oil

    In this lesson, students will be introduced to simple distillation while expanding their knowledge of intermolecular forces. Once a simple distillation has been accomplished in the lab, students will then research the various products of fractional distillation of crude oil and report on one of those products.

  • Interdisciplinary, Concentration, Review, Identifying an Unknown, Culminating Project, Molarity, Balancing Equations, Stoichiometry, Classification of Reactions, Scientific Method, Experimental Design | High School

    Lab: The Culminating Unknown

    In this lab, students identify an unknown from a list of 12 possible compounds by designing a procedure and using evidence to prove their claim. They must draw from knowledge gained throughout the year to properly develop a procedure to identify the unknown.

  • Review, Model of the Atom, Isotopes, Balancing Equations, Atomic Mass, Subatomic Particles, Lewis Dot Diagrams, Electrons, Ions | High School, Middle School

    Activity: Tic-Tac-Toe Review

    In this activity students collaborate to complete tic-tac-toe review questions to prepare for a test on the atomic structure unit. The idea behind the activity is to give students choice and you can read more about the inspiration for the activity in the May issue of Chemistry Solutions.

  • Introduction, Conservation of Mass, Balancing Equations, Conservation of Mass, Limiting Reactant | 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, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules | High School, Middle School

    Lab: Predicting Precipitates

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