B5a The skeletal system

OCR B5a Bare bones, the skeletal system, bones, ligaments, tendons, cartilage, osteoporosis, ball and socket, hinge joint, fixed joint, internal, external skeletons. A ppt based lesson plan for the OCR B5a unit but could be useful for any lesson on the skeletal system. I would probably include a practical looking at the difference in strength between hollow and solid tubes and a look at some insect exoskeletons e.g stick insects.
