  • Observations, Density, Chemical Change, Density, Inferences | 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.

  • Observations, Density, Density, Inferences | 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.

  • Observations, Density, Temperature, Gas Laws, Density, Pressure, Measurements, Matter, Volume, Graphing | Middle School, High School

    Lab: Pressure Bottle

    In this lab, students determine the relationship between volume and pressure of a gas and its temperature and address the common misconception that air does not have mass or density.

  • Observations, Chemical Change, Chemical Change | Middle School, High School

    Lab: Corrosion in Motion

    In this lab, students will expose metal samples to various solutions and observe the amount of corrosion of a period of time.

  • Observations, Chemical Change, Conservation of Mass, Chemical Change, Heat, Temperature, Exothermic & Endothermic | Middle School, High School

    Lab: Kitchen Reaction

    In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.

  • Observations, Chemical Change, Balancing Equations | Middle School, High School

    Lab: Chemical Reactions & Equations

    In this lesson, students will observe a series of reactions, make observations, and then write balanced chemical equations to chemically describe what they observed.

  • Observations, Chemical Change, Reaction Rate, Scientific Method, Experimental Design | Middle School, High School

    Lab: Reaction Rate

    In this lab, students will explore factors that effect reaction rate and develop a general statement that describes how the factors (temperature, particle size, and concentration) effect the rate based on experimental data. This is an inquiry-based activity.

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

    Lab: Observing a Chemical Reaction

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

  • Observations, Separating Mixtures, Physical Properties, Chemical Change, Physical Change, Scientific Method, Chemical Properties, Mixtures, Experimental Design | Middle School, High School

    Lab: Test Tube Separation

    In this lab, students will mix four substances in a test tube and recreate the original four layers through chemical and physical means.

    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 | Middle School, High 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.

  • Observations, Separating Mixtures, Physical Properties, Interdisciplinary, Scientific Method, Mixtures | Middle School, High School

    Activity: How Do We Clean Up An Oil Spill

    In this activity, students simulate an oil spill and test different materials’ ability to “clean” the oil spill.
