Our special guest teacher today was Dr. John Pui, Samantha's dad. As luck would have it, he happens to be a dermatopathologist - a skin doctor! He spends a lot of time looking through microscopes, studying skin samples to diagnose diseases. John brought in two microscopes for us to use this afternoon - a regular slide microscope and a dissecting scope. We got to look up close and personal at our own skin, fingerprints, and other interesting objects.
John also drew a diagram that showed a "map" of that amazing organ, the skin. I was impressed with how much the children had to offer about what they knew about the topic, as well as their very genuine and enthusiastic interest.
