I have a fun and easy digestive system craft activity for you to demonstrate how our stomach breaks down food. Also, I have this Human Body Crafts page for more hands-on ideas. And this Beautiful Human Body Lapbook and Fun Unit Study.
As is appropriate for the preschool and early elementary crowd, it’s a hands-on activity and of course a little gross – making for a very memorable lesson indeed.
The stomach is just one part of the digestive system.
It is one that is easy to demonstrate for young learners and is what we will focus on for this craft/activity.
Let’s look at a simple breakdown of the digestive system.
Basic Steps in The Digestive System
Mouth – This is where your digestive system starts, your saliva helps break down your food as you chew, and then when you are ready to swallow it your tongue pushes the food down your throat and into your esophagus.
Esophagus – In the esophagus the small flap called the epiglottis closes over your windpipe so that you don’t choke on it. Contractions in the esophagus work to deliver food to your stomach.
Stomach – The stomach can stretch and hold up to 4 pounds of food at a time. Once food has reached your stomach it is mixed with enzymes until it is broken down enough to pass onto the small intestine.
Small Intestine – The small intestine is about 22 feet long and breaks down your food even more so your body can absorb all the vitamins, minerals, proteins, carbohydrates, and fats from it.
The nutrient-rich blood then goes to the liver to be processed and stored while the remainder of your food passes into the large intestine.
Large Intestines- The job of the large intestine is to absorb water and electrolytes, as well as forming and propelling feces to the very last stop. Drum roll please – your rectum.
Rectum – Yep, all that leftover food that isn’t used has to go somewhere, it hangs out here until you are ready to go to the bathroom and then it gets pushed out.
Next, look at some of these resources for learning about the human body.

Finally, look at this fun and easy digestive system craft activity.
Digestive System Craft – The Stomach
Before you begin, you will obviously want to explain that this is just one part of your digestive system.
There are a couple of steps before and several steps after that help your food be processed by your body.
You Will Need:
- Ziplock bag
- Red permanent marker
- Black permanent marker
- ¼ cup of soda
- Slice of bread
- Rubbing alcohol
- Dishcloth or paper towel
Once you have gathered all your supplies you can remove the writing from your bag to make it completely see through.
Wet a towel with rubbing alcohol and rub it right off.
You can use a book or google for reference and let your child draw a stomach on the bag in permanent marker.
Have them label the stomach, as well as the tube for the esophagus and small intestine coming out of each end of the stomach.
Tear up the bread into small pieces and set aside.
Pour in a small amount of your soda. This will act as the stomach acids.
Add the bread to the baggie.
You could also use crackers or cookies, just something soft that will break down easily with liquid.
Press out most of the air and seal the bag.
Now for the fun, demonstrate by squeezing the bag how the acids and muscles work to break the food down.
You will see it won’t take long and it is completely broken down (obviously this takes longer during actual digestion).
You can stop here, and you have had a good quick lesson but if you want to add to it a little bit snip off one small corner.
Explain that while there is more to the digestive system than just what is shown on the bag this is what happens at the end when everything that was needed was taken out of the body by the digestive system.
Let them squeeze the waste into a bowl, because after all everybody poops!
