A graduate course for middle school science and high school chemistry teachers is helping them apply the principles of green chemistry throughout the year, bringing the vocabulary and practices of green chemistry to students in grades 7-12. Teachers attend an on-campus 2.5-day weekend laboratory session, completing a series of at least 15 green chemistry experiments and demonstrations, followed by 4 weeks online. They learn strategies for “greening up” favorite experiments, merging green chemistry principles with their existing curriculum, reducing chemical inventory, and designing ways for students to address unwanted products by neutralization, precipitation, and recycling instead of sending all products out as waste. Their students learn to write “Environmental Impact Statements” that describe the means they used to properly dispose of or recycle the unwanted material, complete with chemical equations, and that include a statement about the effects on the environment of their actions.
