  • 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.

  • 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.

  • Cracking, Combustion, Chemical Change, Functional Groups | High School

    Demonstration: Cracking Reaction

    In this demo, students will witness a cracking reaction. They will verify the products by exposing the products to three side reactions.

  • Condensation, Chemical Change, Functional Groups, Lewis Structures | High School

    Lab: Condensation Reaction

    In this lab, students will use Lewis structures to explain the mechanism of an organic condensation reaction between a carboxylic acid and an alcohol, also known as an esterification reaction.

  • Renewable Energy, Chemical Change, Interdisciplinary, Distillation, Molecular Structure, Combustion, Stoichiometry, Chemical Change, Molecular Structure , Enthalpy | High School

    Lesson Plan: Biofuels of the Future

    In this lesson students will explore the world of automobile alternative energy sources through the study of biofuels. They will design and create an e-book that illustrates and explains one of the provided topics or an original idea approved by the teacher.

  • Observations, Physical Properties, Chemical Change, Physical Change, Chemical Change, Temperature, Exothermic & Endothermic | High School, Middle School

    Lab: Observing a Chemical Reaction

    In this lab, students will practice making careful observations and measurements while witnessing a chemical change.

  • Physical Properties, Chemical Change, Identifying an Unknown, Chemical Change, Scientific Method, Chemical Properties, Experimental Design | High School, Middle School

    Lab: As Easy as Pie

    In this lab, students will use chemical and physical properties to identify an unknown powder.

  • 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, Chemical Change, Physical Change, Conservation of Mass, Conservation of Mass, Chemical Change, Measurements | High School, Middle School

    Lab: Mass & Change

    In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.

  • Observations, Chemical Change, Conservation of Mass, Chemical Change | High School, Middle School

    Lab: Conservation of Mass

    In this lab, students perform three simple experiments, recording the mass of a substance before and after a reaction. They then explain how the law of conservation of mass was not violated, even if the mass changed.

  • Renewable Energy, Pressure, Conservation of Mass, Chemical Change, Volume | Middle School, High School

    Lab: Power That Stinks

    In this lab, students will experiment with creating and capturing biogas, and have an opportunity to look at how energy is created from waste. They will explore the differences between non-renewable and renewable energy sources.

  • Classification of Reactions, Chemical Change, Heat, Temperature, Exothermic & Endothermic | Middle School, High School

    Lab: Designing Exothermic and Endothermic Reactions

    In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.

  • Observations, Reaction Rate, Reaction Rate, Chemical Change | Middle School, Elementary School, High School

    Demonstration: Simple Kinetics

    In this demonstration, students will see that different food dyes react with bleach at different rates.

  • Polymers, Polymers, Chemical Change, Chemical Bond | Middle School, High School

    Demonstration: Turn Milk into Plastic

    In this demonstration, students will observe the process of making a polymer, casein plastic, from the casein protein found in milk.

  • 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.

  • Density, Chemical Change, Density, Chemical Change | Elementary School, Middle School, High School

    Demonstration: Fire Extinguisher

    In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.

  • Observations, Chemical Change, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School

    Demonstration: Inflating a Balloon with Chemistry

    In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
