This project is used with my advanced 5th grade class, but could be adapted to a middle school life science classroom. This was a project I used at Open House time to show off as an alternative to the overdone science fair project. After teaching the human body systems in a more traditional setting, I gave students about a week to complete a life-size model of their assigned system that had to have at least 1 3-D component.
Systems included are Circulatory, Respiratory, Skeletal, Muscular, Nervous, and Digestive. Each group has individualized instructions for their project, but the amount of work is fairly equal among the groups.
Students have loved this activity each year I have done it, and it has been a hit with open house visitors. This really showcases how much the students have learned, but also challenges them to work cooperatively and creatively with a group.
