Summary
Green chemistry focuses on developing sustainable and environmentally friendly practices within the field of chemistry. An effective approach to introducing this concept is through the exploration of the 12 Principles of Green Chemistry, which serve as a guiding framework for creating safer, more efficient, and environmentally conscious chemical processes. By incorporating these principles into our teaching, we can inspire students to become catalysts for positive change in the world of chemistry and beyond.

This lesson is for use as part of an introduction to high school chemistry lab. Teachers need to have information on the 12 Principles of Green Chemistry and how to use them to evaluate a lab procedure (see appended list of the principles at the end of this document). This lesson will be set up as both an at-home (remote learning) and in-class lab activity taking into account social distancing.

NGSS Standards, if applicable
• HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns in chemical properties.
• HS-PS1-5. Apply scientific principles and evidence to explain how the rate of a physical or chemical change is affected when conditions are varied.
Learning Goals/Student Objectives
Students will…
• Understand the basics of the 12 Principles of Green Chemistry.
• Use weight and measurement to understand the concept of a recipe as it is applied to a chemical process.
• Think critically about a process and how it might be improved.

Safety Precautions, Hazards, and Risk Assessment
• Students will use hot plates and glassware, as well as cut fruit with a knife. Practice standard laboratory safety.
• If in the classroom, students will be required to wear their safety glasses as we make this a requirement for all labs no matter what we are using.
• Be sure to check for food allergies in the students with whom you intend to do this lesson.
