Yavneh seventh graders culminate their study of the human body by creating their own Human Body Expo. The bodies presented at Yavneh’s expo are made from recyclable garbage. The goal is to create a body showcasing the body systems learned in class. Each group of students create a prototype with drawings, measurements and a list of materials to help guide them through the building process. The project included an interactive component showing the functions of the systems and seventh graders present their projects to the early childhood classes. The students become teachers as they guide the younger students through their projects.
