Recycling Rules: Understanding Recycling and MRF

This is an excellent lesson because it is subject that students are familiar with regardless of if they recycle or not. The lesson goals were clear and concise likewise the introduction to stem. I really enjoyed the background information because it provided students with scaffolding. Also, materials are familiar to students. Students were able to practice and record predictions, students were able to do the experiment. However, I feel that while this was a great lesson, it did not have all the components of a stem design.
