1 – 15 of 15 Classroom Resources

  • Renewable Energy, Introduction, Interdisciplinary, History, Polymers, Heat, Molecular Structure | Middle School, High School

    Video: Frontiers of Chemistry

    This video explores new scientific developments that were made possible by the application of fundamental chemistry concepts. Students will learn about exciting advances in science and technology focused on three main topics: Solar Cells, 3D Printing and Micro Machines.

  • Reaction Rate, Reaction Rate | Middle School, High School

    Simulation: Reaction Rates

    In the May 2018 simulation, students investigate several factors that can affect the initial rate of a chemical reaction, including concentration, temperature, surface area of the reactants, and addition of a catalyst.

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

    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.

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

    Activity: Balancing Equations with Note Cards

    In this activity, students will balance equations and get immediate feedback on whether they are accurate or not while trying to solve a challenge. This activity works best as a review activity after balancing and the law of conservation of matter has been taught.

  • Reaction Rate, Reaction Rate | Middle School, High School

    Activity: Simulation Activity: Investigating Reaction Rates

    In this simulation, students will have the opportunity to investigate several factors that can affect the initial rate of a chemical reaction. Students will have the opportunity to manipulate several variables including concentration, temperature, or surface area of the reactants as well as the addition of a catalyst during the simulation. These reaction rates will be compared to a controlled reaction. Students will interpret a simplified qualitative representation of the reaction as well as analyze corresponding data organized on a graph.

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

    Activity: Balancing Legos

    In this activity students use Legos to model the reactants and products in a chemical reaction. They use these “atoms” and “molecules” to balance the chemical reaction in order to demonstrate the law of conservation of matter.

  • Balancing Equations, Conservation of Mass, Photosynthesis | Middle School

    Activity: Achieving a Photosynthetic Balance

    In this activity, students will use candies to model the rearrangement of atoms from reactant to products during photosynthesis.

  • Chemical Change, Phase Changes, Interdisciplinary, Culminating Project, Conservation of Mass, Chemical Change | Middle School, High School

    Project: Law of Conservation of Mass Comic Strip

    In this project, students will work in groups to create a comic strip that illustrates understanding of the law of conservation of mass.

  • Classification of Reactions, Chemical Change, Temperature, Exothermic & Endothermic, Activation Energy, Energy Diagrams, Bond Energy | Middle School, High School

    Activity: Simulation Activity: Energy Changes in Chemical Reactions

    In this simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Through the use of this simulation students will have the opportunity to compare how energy is absorbed and released in each reaction. Additionally, students will make a connection between the standard energy diagrams associated with each reaction type.

  • 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.

  • Combustion, Heat, Exothermic & Endothermic, Heat of Combustion | Elementary School, Middle School, High School

    Video: The Internal Combustion Engine Video

    This video investigates both the mechanical and the chemical processes used in the internal combustion engine, as well as the history and evolution of the combustion engine.

  • Catalysts, Reduction, Combustion, Redox Reaction, Activation Energy, Oxidation | Elementary School, Middle School, High School

    Video: Catalytic Converters Video

    This video investigates the role of a catalytic converter and its corresponding chemical reactions within a vehicle. Students will learn about both oxidation and reduction reactions and how they, in combination with a catalyst, can impact the molecules released in a car’s exhaust.

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

    Activity: Snowman Challenge

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

  • 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.
