Green Chemistry
in the High School:

Lessons from
Beyond Benign

"For Teachers, By Teachers"

 

The High School level Green Chemistry lesson plans from Beyond Benign are designed to give teachers the tools to both do and teach green chemistry in their classrooms. The lessons are divided in to three sections, each of which is listed below.

Teachers who wish to infuse Green Chemistry into a regular Chemistry course at the high school level should use the "Curriculum Mapping" document to augment their established curriculum and replace laboratory activities that use and teach techniques and materials that are hazardous to human health and the environment. The topic areas are those typically included in a high school introductory chemistry course.

Section 1. What is Green Chemistry?

Featuring lessons that define green chemistry and introduce the 12 principles of green chemistry

"What is Green Chemistry
from the American Chemical Society" -
[ppt]

  • "Writing the Principles" - Use a lab-based simulation to introduce the 12 principles of green chemistry in an accessible way.

Section 2. Green Chemistry in Industry

Featuring lessons inspired by industry examples and current green chemistry research efforts in the field. Lessons are linked to national learning standards.

  • "VBT" – Bio-inspired Polymers: Students learn about a new technology to make the manufacturing of small electronics safer. [doc]

  • "Dye-Sensitized Blackberry Solar Cell" - Students create their own solar cell using non-toxic materials and blackberry fruit as the dye, understanding how solar cells are manufactured currently and the green chemistry research towards greener solar energy devices.

  • "Recycling Polylactic Acid" - Students learn how to take a renewable product, a PLA plastic cup, and extend its lifetime by converting the cup into a cleaning solution.

    Download: [doc]

  • "Climate Change Chemistry" - In this unit students consider the chemistry behind the concept of climate change while exploring gases and gas laws.

    Download: [doc] [ppt]

  • "Green Chemistry, Biomimicry and Intermolecular Forces" - Students explore the use of adhesives, intermolecular forces and how biomimicry is being used by chemists to invent greener alternative products.

    Download: [intro doc] [lesson doc] [ppt]

  • "Chemistry of Cosmetics" - Students look at the materials used to make common cosmetics products. They look at the molecular structure of organic compounds and how the shape of the molecule effects the toxicity and potential health hazards that have been associated with cosmetic ingredients.

Section 3. Green Chemistry Replacement Laboratory Exercises

Featuring replacement lessons for core teaching concepts that use green chemistry principles. Lessons are linked to national learning standards.



  • "Acids, Bases and pH" - Students measure the pH, categorize or group substances based on physical properties and observe physical properties of acids and bases.

    Download: [doc]

  • "Catalysts and Oxygen" - This lab replaces manganese dioxide to demonstrate the effect of a catalyst in a reaction. Students will understand the concept of a catalyst and reaction rates, and how a catalyst can improve the efficiency of a process.

    Download: [doc]

  • "Enthalpy of Combustion"- Investigating the molar heat of combustion of paraffin, compared to soy wax, students will be able to measure the thermal heat absorbed by water, measure the heat of combustion of paraffin and soy wax and calculate the molar heat of the combustion of paraffin.

    Download: [doc]

  • "Equilibrium/Le Chatelier's principle" - This lesson gives students an understanding of the concept of chemical equilibrium and demonstrates Le Chatelier’s Principle.



    Download: [doc]

  • "Exothermic and Endothermic" - Many teachers use the calcium chloride and ammonium nitrate reaction to show exothermic and endothermic reactions. This alternative method uses a catalase, an enzyme found in nearly all living organisms. Students will perform an exothermic reaction, an endothermic reaction and a change in enthalpy (∆H) in an endothermic reaction.

  •  "Flame Tests and Emission Spectra" - Traditionally, flame emission spectra labs use solutions of toxic metal salts in Bunsen burners. Even when used on microscale the metal ions in the salt solutions become volatized. This redesigned lab uses candles with colored flames that burn at a much lower temperature and eliminates the preparation and disposal of the salt solutions. The candles burn slowly and may be observed concurrently, giving students sufficient time to compare and contrast the emission spectra.

  • "Moles, Atoms and Grams oh my!" - This lesson practices the concept of the mole and the calculations involved in understanding how moles are used.

    Download: [doc]

  • "Solubility" - Students qualitatively and quantitatively describe the relationship between temperature and solubility for gases and solids. This lab uses two forms of magnesium (magnesium chloride and magnesium sulfate) to compare solubility of ionic solids and create a solubility curve. Solubility of gases is demonstrated by a simple demo experiment involving carbonated water and temperature differences.

  •  "Sublimation" - This lab replaces the traditional naphthalene sublimation lab. Students will observe sublimation (physical properties of matter) and explain the type of change that occurred.

    Download: [doc]

  • "Reactions Lab" - In this lesson students observe reactions and identify the type and products produced in those reactions and compare the reactions for their toxicity using the 12 principles of green chemistry.
