  • Gas Laws, Pressure, History, Volume | High School, Middle School

    Activity: Robert Boyle Video Questions

    In this activity, students will watch a video and answer questions about Robert Boyle. They will learn about his impact in chemistry, including Boyle’s Law which describes the relationship between pressure and volume of a gas.

  • Temperature, Kinetic Molecular Theory, Heat, Temperature | High School, Middle School

    Lab: Mega Marshmallows

    In this lab, students will investigate the Kinetic Molecular Theory and particle motion while experimenting with a marshmallow. Students will observe how an increase in kinetic energy will cause particles to increase in motion. This concept will be extended into a discussion about additional real world thermal expansion examples.

  • Temperature, Heat, Temperature | Middle School, Elementary School

    Demonstration: An Uplifting Experience

    In this demonstration, students will investigate what happens to air when it is heated.

  • Temperature, Pressure | Middle School, Elementary School

    Demonstration: EGGsperiment

    In this demonstration, students will learn how temperature change affects air pressure, while observing an egg getting sucked into a bottle without being touched!

  • Temperature, Gas Laws, Volume | Middle School, Elementary School

    Demonstration: Candle Mystery

    In this demonstration, students will observe and analyze how the change in temperature of a gas can affect the volume of a gas.

  • Gas Laws, Pressure, History, Volume | High School, Middle School, Elementary School

    Video: Robert Boyle Video

    This video tells the story of Robert Boyle, a great chemist and discoverer of Boyle's Law, which describes the relationship between pressure and volume of a gas.

  • Temperature, Gas Laws, Pressure, Kinetic Molecular Theory, Volume | High School, Middle School

    Animation: Gases Animation

    In this animation, students will visualize how volume, temperature, and quality of a gas are related. This is done qualitatively and quantitatively. **This video has no audio**

  • Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: Investigating Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.

  • Gas Laws | Middle School, High School

    Activity: Hot Air Balloon

    In this activity, students build a hot air balloon to aid in their study of Charles’ law.

  • Temperature, History | High School, Middle School

    Lab: Greenhouse Gas Simulation

    In this lab, students will create two simulations of the Earth’s atmosphere. They will compare a control model with a one that has an increased presence of carbon dioxide gas in order to analyze how this effects temperature. They will also complete research in order to learn more about the makeup of the Earth’s atmosphere.

  • Gas Laws | Middle School, High School

    Simulation: Gas Laws Simulation

    In this simulation, students will investigate three of the fundamental gas laws, including Boyle’s Law, Charles’ Law and Gay-Lussac’s Law. Students will have the opportunity to visually examine the effect of changing the associated variables of pressure, volume, or temperature in each situation. Also, students will analyze the gas samples at the particle level as well as manipulate quantitative data in each scenario. Finally students will interpret trends in the data by examining the graph associated with each of the gas laws. This lesson accompanies the simulation from the November 2015 issue of Chemistry Solutions.

  • Gas Laws, Pressure, Kinetic Molecular Theory | Middle School, High School

    Simulation: Gas Law Variables

    In this simulation, students investigate variables of a gas. From the computer models, they can see how pressure, temperature, and volume effect gas behavior.

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

  • Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School, Elementary School

    Lab: Rocket Challenge

    In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.

  • Density, Density | Middle School, High School

    Demonstration: Qualitative Look at Gas Density

    In this demo, students witness three types of gases and observe their relative densities to air.

  • Gas Laws | Middle School, Elementary School, High School

    Demonstration: Egg-citing Gas Laws

    In this demonstration, students will observe how changing the temperature of a gas will affect the pressure of the gas through an engaging demonstration using a heat source, water vapor and a hard-boiled egg.

  • Sublimation, Chemical Change, Pressure, Phase Changes, Physical Change, Boiling Point, Chemical Change | Middle School

    Lesson Plan: Dry Ice

    In this lesson, students will investigate how dry ice undergoes a phase change from solid to gas, skipping the liquid phase under normal temperature and pressure.

  • Gas Laws | Middle School, High School

    Demonstration: Crush the Can

    In this demonstration, students will analyze how the change in temperature of a gas can affect the pressure and volume of the gas. Students will watch an engaging demonstration involving a heat source, water vapor and an empty soda can.

  • Density, Density | Middle School, High School

    Demonstration: Comparing Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.
