Digestive System for Dolphin Swimmers and Time Travelers

The Digestive System

This week was our last week to explore the body.  We watched a video from Operation Ouch about the digestive system, and then explored how saliva and chewing start the digestive process and then how the esophagus, stomach, small intestine, and large intestine work.  Measuring out lengths of yarn to represent each of these organs, we explored how long (and short) they were.

Here are some questions you can ask your child:  

  • What happened to the cracker that you put on your tongue?  How was it different from the cheese?
  • In the video we could see the actual insides of the stomach, small intestine, and large intestine.  Did anything surprise you about those images?
  • What happened to the slice of bread that you mashed up in the bag (representing the stomach)?  
  • What happened with the oatmeal that was passing through the pantyhose?  If that represented the small intestine, what happens in the small intestine?

Since we had many students out sick, our activities went quickly.  We added some exploration about the immune system.  We watched a KidsHealth video and explored how germs can be spread by sneezing and on our hands.  

You can ask your child: what kinds of things can you do to keep your body healthy and help it fight germs when you’re sick?
