I just realized I forgot to post our Earth Day studies! This year we focused on recycling. It was amazing for the parents in our group to realize that we were recycling improperly! I highly recommend obtaining info on recycling from your local recycling plant. You may be surprised at what you learn. Some recycling plants even host tours which is great. Ours does not provide tours for younger elementary students but they did give us a great video that we got to watch and keep!
The kids had a great time playing Recycling Bingo and then I used the bingo cards to do a Recycle sort game.
