Inquiry Experts

In the last two weeks, our class has enjoyed presentations from a doctor and a dentist.  Last week, JM's dad (who is a gastroenterologist) and mom came and talked to us about the digestive system.  JM's dad brought a special scope that he uses to look down a patient's esophagus, and JM's mother made miniature digestive systems for us to  play with.  We saw real pictures of the esophagus, stomach, small intestines, and large intestines, and then we mashed up crackers, water, and oatmeal to push through the miniature digestive systems (balloons, baggies, and stockings!)  We learned how food travels through the esophagus, stomach, and intestines.  Thank you to JM's family for a great presentation!  On Wednesday, BH's mom (who is a dentist) visited our class to talk to us about teeth.  She brought dental health worksheets and goody bags for all the students, and shared x-rays and models of teeth with us.  We watched a video about cavities, and got to see how dentists use a special light to make tooth fillings hard.  We learned that teeth are not made out of bone and that bacteria eats the sugar that junk food leaves on our teeth.  Thank you to BH's mom for teaching us how to take care of our teeth!
