When we did a study of the body, I thought it would be interesting to have some x-rays around. I found that Doctor’s offices will just give old x-rays to you if you just ask. They will first mark out the patient information on each, but they are yours to have. My son had been seeing an orthopedic surgeon for years, and he gave us a whole pile that covered head to toe! We then displayed them on the windows as the sunlight made them easy for the children to see. They had to guess what each body part was on each x-ray. They were fascinated, as were the parents!
