How it Works and How to Look After It by Susan Meredith. E.D. C. Publications, 1983. Borrow a skeleton from a teaching hospital if available. Also approach doctor's offices for models of human systems for classroom display. Teach the unit during October to coincide with Halloween and incorporate the jointed human skeleton.
Teacher runs off handouts, students cut, assemble and join skeleton with brads.
For your parent presentation you can teach the kids the lyrics and have the children assemble on stage with their portable skeletons that they have assembled.
