Magic School Bus activity that gives directions for creating a decay bottle out of soda bottle. I would use this for exploring decomposition with elementary students. They can observe it happening instead of guessing!! Yay!

This website includes several different lesson plans on recycling. The one that I enjoyed the most is teaching them how long trash lasts, discusses decomposing along with other things. The lesson plan includes what subject areas are included in the lesson, a brief description, grades, objectives, keywords, materials, along with many other key components. It is a very good lesson for teachers to use as a guideline.

While this is interesting information, the activity focuses on a lot of guessing without linking to prior experience or involving students in finding out for themselves. You say "guideline" as a use, and I would suggest it be only that, perhaps related to a unit on food chains that involves the concept of decomposition. Students could design their own experiment to observe the decomposition of different objects over time.

This is a lesson plan for a pre kindergarten classroom learning about recycling. They are not only learning about recycling, they are also learning social skills. Since they are working in groups and then they speak to the class as a whole. I like this website because there are many other lesson plans as well, and they are easy for teachers as well.

I'm going to argue with the categorization of this as Pre-K, even though that is what the website itself says. 3 & 4 year-olds do not know the reasoning behind recyclable/non-recyclable items. Older students could research this or design tests to find out about decomposition, etc.

Composting is the oldest form of recycling. It provides an opportunity for students to observe the decomposition process and energy cycle at work; produces a valuable soil supplement; and reduces the amount of organic material requiring a landfill or incineration. This is a neat hands on lesson that can last up to the whole year! The students get to understand the process of composting and will learn that there we can use other methods of eliminating our trash. My favorite part is that they get to physically see what is happening in the soil. I would start this activity towards the beginning of the year. The students can volunteer to bring in items from the materials list to help feel involved in the prep. I would have the students keep a journal about the chances they see when we check on the compost bin.
