I think this is a great way to get students to think creative and critically. I also noticed that there is no time frame to complete this activity and this does not seem like a lesson to me. I feel that there is not much information about this activity and much prior knowledge is needed. I think demonstrations and such should be included in this. It could be better if there were examples, step-by-step directions on the mechanics of how to incorporate the batteries and such, etc. I think this is a great start, but it does not give enough information for the students to learn why to recycle or why it is great to use these tools. I really do not think that this activity makes them appreciate using waste products or the value of recycling.
