We had a guest in our class today: Dr. Sara Brown came in to teach the kids about the respiratory system and the harmful effects of smoking. The students were able to share their knowledge as well, which really added to Dr. Brown's presentation/ lesson. She brought stethoscopes so the kids could listen to their lungs before and after exercising. She also brought pig lungs: one healthy set and the other with the effects of a long time smoker (emphysema, cancerous)
