On Friday the 13th a presenter from the City of Surrey, Kathy, came and talked to us about waste. She talked to us about the 'life cycle' of jeans. She talked about how they are made, and how they affect our environment. She also taught us what to put in the green bin, blue bin, and black bin. She told us about what not to put in those bins. For example, we should not put glass in the recycling because it messes up the recycling machines. At the end of the session we played a mini game of bingo. Not everybody won but it was still a fun game!
