Objective: At the end of the lesson, students will be able to: -Define the term “green chemistry.” -Explain why green chemistry is important. -List some of the techniques used in green chemistry.

Materials Needed: -White board -PowerPoint slides -Student worksheets

Procedure:

1. Introduction: -Introduce the topic of green chemistry and explain why it is important (it reduces waste and pollution by using less hazardous materials and processes). -Ask students why they think green chemistry is important.

2. Lecture: -Explain to students that green chemistry is a philosophy that focuses on the design, development, and implementation of processes and products that reduce or eliminate the use and generation of hazardous substances. -Explain that there are several techniques used in green chemistry, including the use of safe solvents, catalysts, and renewable feedstocks. -Discuss with students each of the techniques and give an example for each.

3. Activity -Divide students into small groups. -Give each group a worksheet that has a list of green chemistry techniques and corresponding examples. -Ask each group to discuss the techniques and come up with their own examples. -After 10 minutes, have each group present their examples to the rest of the class.

4. Discussion/Conclusion -Review the objectives that were taught in the lesson. -Discuss with students why green chemistry is important and why we should strive to use it in our everyday lives. -Have students share any questions they have about green chemistry or anything they found particularly interesting.

5. Assessment -Have students complete a written assessment that covers the topics discussed in the lecture.
