D is for Doctors

For week 2, we decided to focus on doctors, or more specifically, medical doctors and dentists. These are broad topics so we narrowed our discussions to: types of teeth, parts of the teeth/gums, healthy eating, a doctor's job/equipment and touched on anatomy as well.

Art project: Painting a yellow tooth white. I had planned for her to use a toothbrush to paint, but she was not interested. The white paint is mixed with corn syrup for more sheen.

Working on her food pyramid using clippings from magazines and grocery store fliers.


Classifying the food into the major food groups


This was one of my favorite activities (and Lily's too). We took various healthy foods and tested whether or not they would sink or float in water.


Lily made her predictions beforehand, and then we charted the results. I could not believe that she only got one wrong! I would have done far worse.


Science experiment #2: Examining the effects of unhealthy foods on teeth. In order to demonstrate this point, one boiled egg was submerged in cola and the other in vinegar. The first egg (in cola) shows what happens to teeth without brushing them. The second egg (in vinegar) shows what happens to teeth that are not cared for over a long period of time.


Lily was fascinated with the process.


The next day, we took the eggs out in order to see/feel what had happened. The shell (representing enamel) completely broke down in the vinegar. It was discolored with the cola.


Lily used toothpaste to clean the discolored egg. It actually works! You can kind of see the difference in color between the picture above and this picture.


Art project: Making doctor bags


While making her doctor bag, Lily said, "You know what would REALLY make them [the patients] feel better? Cotton candy!"
