  • Observations, Chemical Change, Conservation of Mass, Chemical Change, Exothermic & Endothermic, Heat, Temperature | 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.

  • 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.

  • 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.

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