I was going to start out reading the book Trashy Town to the kiddos before starting our activity (I included a link to a read aloud below as well). I initially saw this activity on Instagram by @stemsational_stem and LOVED it! The goal for the students would be to create a trash and/or recycle bin that that will hold all of the provided trash or recyclable items. I created a printable that has items on one side and trash cans with numbers on the back (the numbering was honestly more for my sake in keeping materials separated!). This could still be done even without the printables - simply cut out pieces of paper and write or draw items on them or even wad up pieces of paper to make trash balls. Simply use whatever materials you have in the house - LEGOs, paper and tape, recyclable materials, or things you find in nature, etc.
