This is something I did in my classroom this year when I was talking to my preschool class about how we are all different, yet the same. It is a wall display of the children in my preschool classroom. The children were asked to search for their own eyes and when the parents came in later that day, I asked them to find their child's eyes too!
Human Body Systems project for Grade 5: Have students divided into groups, each group is responsible for making a model of one of the human body systems. Have the groups do research on the function of the system and then present their information to the class along with the model. My students LOVED this project!
