We block off a section of the parking lot for our event and have one class ride at a time for safety. It turned out really cute. You need one empty thread spool, and two pipe cleaners for each child. Take one pipe cleaner and stick it though the spool and bring it back to the top and tie it. Then take the pipe cleaner that is on the spool and tie it to the middle of the other pipe cleaner.
Children can put the stethoscope on like eye glasses.
Most students who are studying to be dentists, dental hygienists, or dental assistants or required to do so many community training sessions. They will come to your school to teach your students in a fun way about proper dental care and they will probably get a bag with a new toothbrush and other dental goodies to take home. They also make great visitors for community helper month. I use a glob of paint in the palm of my hand after reading the book to show where the germs go even if I cover my mouth when I've coughed. I read the book at least once a month to review, and also for any new ones who've joined our group.
