176 – 192 of 192 Classroom Resources

  • Chemical Change, Gas Laws | High School

    Access is an AACT member benefit. Project: Air Bag Stoichiometry

    In this lab, students make real-world connections of stoichiometry with the design of car air bags.

  • Limiting Reactant, Acid Base Reactions | High School

    Access is an AACT member benefit. Lab: Acid/Base Stoichiometry

    In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.

  • Oxidation, Chemical Change, Oxidation, Reduction, Redox Reaction, Electrons, Electron Transfer | Middle School

    Access is an AACT member benefit. Lesson Plan: Old Rusty

    In this lesson, students will explore the concept of oxidation of metals by creating designs on fabric or paper using rusty objects.

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

    Access is an AACT member benefit. Lab: Observing a Chemical Reaction

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

  • Observations, Combustion, Phase Changes | High School

    Access is an AACT member benefit. Lab: Observing a Candle

    In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.

  • Chemical Change, Chemical Change, Observations, Acid, Chemical Change | Elementary School

    Access is an AACT member benefit. Lab: My Pennies

    In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.

  • Limiting Reactant, Classification of Reactions | High School

    Access is an AACT member benefit. Lab: Mole Relationships in a Single Displacement Reaction

    In this lab, students will carry out a reaction between metallic copper and an aqueous solution of silver nitrate to determine the mole ratio between the reactants and the products and write a balanced equation based on the data.

  • Chemical Change, Combustion, Balancing Equations | High School

    Access is an AACT member benefit. Demonstration: Methane Bubble (Dragon Ball Z)

    In this demonstration, students will observe the combustion of methane using hands-on practices.

  • Stoichiometry, Gas Laws | High School

    Access is an AACT member benefit. Lesson Plan: Mechanisms and Properties of Airbags

    In this lesson students will learn about the mechanisms and properties of airbags, and examine the choice of airbag inflator from several points of view.

  • Conservation of Mass, Matter | High School

    Access is an AACT member benefit. Lab: Matter Matters

    In this lesson, students will investigate the Law of Conservation of Mass.

  • Conservation of Mass, Measurements, Conservation of Mass | High School, Middle School

    Access is an AACT member benefit. 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.

  • Chemical Change, Observations, Mixture, Acids & Bases, Chemical Change | 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.

  • Exothermic & Endothermic, Classification of Reactions

    Simulation: Energy Changes in Chemical Reactions

    In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.

  • Molecular Formula, Ionic Bonding, Covalent Bonding, Molecular Structure, Naming Compounds

    Simulation: Ionic & Covalent Bonding

    In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.

  • Le Châtelier's Principle, Establishing Equilibrium, Reversible Reactions, Reaction Rate | High School

    Access is an AACT member benefit. Lab: Dynamic Equilibrium Simulation

    In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.

  • 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.
