Human Body: Digestive System

This is the area of the human body that my daughter has been so anxious to study! Hilarious, seeing though most people are grossed out by the whole process. :) I have to honestly admit that I, as an adult, am learning so much about the human body.

Our body has a digestive system now! Yippee! 

We did a couple activities to start off our learning exploration. First, we just talked about the whole process. Boo was just naturally inquisitive about this topic, so it wasn’t another boring lecture (think of Charlie Brown’s teacher!) I explained everything from the mouth to the large intestine and everything in-between. We also talked a little bit about the liver and how it produces bile. This was especially of interest to Boo because our dog Sammy had a sock stuck in his duodenum (part of the small intestine) and would throw up bile. At first Boo was proud that Sammy threw up the icky green liquid- I had to explain to her that bile coming out of our mouth is not a good thing!

Our next learning activity was watching this short clip on the digestive system. My daughter thought this was SO fascinating. I like that it was short and sweet, and used proper terminology. I got the idea to use this clip from Spell Outloud. We watched the movie AT LEAST five times per Boo’s request!

It was time for a more hands on activity using a paper towel tube, baggie, water, and bread (another activity inspired from Spell Outloud.
The paper towel tube was our esophagus and the bag of water was the stomach and stomach acid. As we put pieces of bread into the esophagus, we discussed how it is a tube with muscles that help move the food down towards the stomach.

Once the bread reached the stomach, we talked about how the acids break it down into smaller pieces called chime. As you can imagine, watching bread turn into a liquidy goop was extremely fascinating and we had to repeat the experiment a few times.

“WOW! Can we do this AGAIN?” I just love this face!

The last step was adding the digestive system to our body! I know the proportions are off a bit- but I am still happy with how it turned out!

The lower part of the digestive system: liver, pancreas, gall bladder, stomach,  and small and large intestines. 

I hope that in some way this will help and inspire you as you teach your kiddos about the digestive system!
