1 Check out the Matrix of Lessons and Conceptual Content on page 20. You'll see how each lesson helps you meet intermediate-level guidelines for student science literacy.

2 Review the background information in the first section of the kit for a basic understanding of the can manufacturing process. A simpler handout describing this process has been created and is provided for students. Consider using it as homework reading, or integrate it into the lessons where appropriate.

3 Explore! This kit contains ready-to-use lesson plans, supplemental handouts and hands-on materials that you can use to engage your students in environmental education. Each lesson contains detailed procedures, wrap-up activities and ideas for extracurricular projects. Adapt lessons and points of emphasis as you see fit.

4 Many activities are interactive. If your school is lean on science equipment or if your students function best in a more structured, teacher-directed environment, consider demonstrating the activities yourself.

5 If you like these lessons, share them with other intermediate-level (fourth through six grade) teachers. Many activities can be adapted in breadth and depth to appeal to older students.

6 The best way to ensure that the issues considered in this curriculum make a lasting impression is for students to plan an action project related to their case study of aluminum cans. Use the information provided in Lesson 7 and The Great Aluminum Can RoundUp competition materials included in this kit as a starting point.
