    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.

  • 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).
