Science PBL Presentation

My class worked for over a month on a Science PBL on food chains.  They were to research what affects food chains in a negative way, and then they were to come up with ways to help the food chain even as a 3rd grader.  We picked up litter, raised money and adopted an Amur Leopard, reused and recycled our materials, and we wrote thank you letter to firefighters for helping put out forest fires.  We then invited our parents in to our presentation.  We had a lot of fun doing this.  Afterwards, we put all of our projects in the glass case at the end of the hallway.
