  • Kathe Skyline Green Chemistry

    1. 1. Thinking Green While Teaching Chemistry at Skyline High School
    2. 2. How we got started • Skyline High School - Ann Arbor, Michigan • LEED certified building • Geo-thermal • Recycled materials • Wind Turbine
    3. 3. What does Green Chemistry mean at Skyline? • Preventing Pollution • Using less energy • Using fewer or safer chemicals • Sustaining the Earth/ Civilization
    4. 4. How does Green Chemistry works towards SUSTAINABILITY at Skyline? • Using chemicals that do not harm either our health or the environment. • Using industrial processes that reduce or eliminate hazardous chemicals. • Designing more efficient labs that minimize the production of waste materials and decreases the amount of non-renewable energy used. • Incorporating Green technology and educating our student to address the three E’s when conducting investigations. • Social Equity • Economics • Environment
    5. 5. Our Science Department’s Mission • Developed a Sustainable/Green Chemistry course • Goals • Raise student’s awareness of Green Chemistry and its 12 Principles • As a department adhere to these principles when designing experiments.
    6. 6. S/G Chem I Taken by all tenth graders Students will be prepared to take AP Chemistry or S/G Chem 2 I trimester course; covers some Chemistry HSCEs Instructors practice green chemistry methods Students learn about 12 principles of green chemistry and investigate and conduct Presidential Green Chemistry Award processes.
    7. 7. Opinion Activity • First day of class • Great activity to do outside with students. • Have students trade answer sheets and try to explain why that person gave the answer.
    8. 8. Second Day of class • Defining Sustainability • Students are asked to brainstorm what they would like to see last beyond their lifetime. • Break it down into the Three E’s • Environment • Social Equity • Economics
    9. 9. 12 Principles of Green Chemistry • Pollution Prevention • Atom Economy • Less Hazardous Synthesis • Design Safer Chemicals • Safer Solvents • Energy Efficiency
    10. 10. 12 Principles of Green Chemistry • Renewable Feedstocks • Reduce Derivatives • Catalysis • Design for Degradation • Real-Time Analysis • Accident Prevention
    11. 11. You expect me to explain this to a teenager!! • Synonyms Simplify • Activity that starts with common sayings and turning them into scientific terminology • Example: Homo sapiens who reside in vitreous domiciles should not launch geological pieces. • Students in groups are assigned one of the 12 principles and they simplify it.
    12. 12. Recipe Rescue • Making Lemonade • Using lots of unnecessary ingredients as a batch of lemonade is made. • Students write in their journals what things were not necessary and what could be changed.
    13. 13. Atom Economy • We use M & M’s where the green ones are the molecules that we want and every other color is waste.
    14. 14. How Green is my Orange • Supercritical CO2 • Students extract the essential oil d-limonene from the rind of orange peels. • Use both steam distillation and supercritical CO2 • Compare the use of hazardous chemicals in both extractions and energy costs.
    15. 15. Three E’s Triangle
    16. 16. S/G Chem 2 Two trimester course Covers state HSCEs for Chemistry for 1.0 credit Includes units in toxicology, organic, and polymer chemistry
    17. 17. Trick out my Wheels • Manufacture a car paint that adheres to the principles of green chemistry as closely as possible in all areas of the manufacturing process.
    18. 18. Toxicology Unit • The Dose Makes • Environmental the Poison Hazards. • Dose Response • Research paper on Relationship organic molecules and its toxicity. • What is the Risk? • Organic structure and toxicity
    19. 19. Polymers • And the Award goes to ... Petretec • Students build dimers of polyethylene terephthalate (PET) as used in water bottles. • Dimers are put together to make the polymer and find it cannot be broken apart back to dimers.
    20. 20. Purpose of Petretec Activity • Look at PET plastic and consider its end use. • Understand various types of plastics formation. • Consider whether plastics are sustainable. • Consider lifecycle of a plastic • Difference between closed-loop and open- looped recycling. • Look at green chemistry award winning technology
    21. 21. The Footprint of a Chemistry Teacher • Science teachers are acutely aware of the environment. • We also have a footprint in our chemistry classrooms that can have a profound effect on the earth. • We tend to conduct labs with very little thought as to the impact of our classroom on the environment.
    22. 22. Two most important properties of matter that we want to emphasize in our chemistry courses. •Toxicity •Impact on the environment
    23. 23. Chemistry in the 21st Century • Before we begin an experiment: How have our starting materials been made? • Can we trace them back to renewable resources? • How much waste is generated from the process? • What happens to our waste? • From where do we get the energy needed for the reaction and how is it generated? • Finally we will end up with a complete picture of not only what happens in our experiment but how our reaction interacts with the environment. • In most cases it will be difficult to determine all parameters in exact measures, but even rough estimates allow the identification of problems and opportunities for improvement. • Asking these questions in our laboratory courses will change the way students look at a chemical reaction and prepare them much better for the professional tasks.
    24. 24. Why change the way we teach chemistry in high school? • C & E News Letters to the Editor August 7, 2006 • “But we should not lead our society to think chemists should be able to develop nontoxic materials. Let us provide training with a proper basis so that “armies of students will rise to the challenge and work to invent a safer future.”
