This is my idea for my lesson plan:

• Have the students research recycling, recycling programs and things that people can do in everyday life.
• Get into groups and have them brainstorm (based on their research) what we could do as a class to facilitate recycling.
• Present to the class their ideas with visuals
• Have the class vote on what program they would like to start in our class.
  
• Then work with the ideas and put it into effect into the classroom!

What do you think? When I write my lesson plan I'm going to expand on a lot of these ideas. This was just my thinking. Let me know if you have any feedback!
