We Know How to Eat – But Do We Know What Happens to our Food After We Eat It?


We all know food is an important source of energy – and we know HOW to eat,  but do we really know what happens to our food AFTER we eat it?
All second grade students took time to do a great hands-on project that walked them through how their bodies digest food.
It’s part of the second graders weekly experiments to practice the Scientific Inquiry Process. This experiment explored one of the human body systems – the digestive system.
Students were assigned “digestive system roles” – to mimic a meal traveling through a person’s organs.
Take a look at this exciting – and very visual – hands-on approach to learning about our digestive systems!

Students had a plastic bag which represented a stomach, cheese cloth to represent the small intestine, a paper plate to catch the “nutrients” and two cups used to collect the “waste”.
Students assigned to “saliva” got to add water.
Students assigned to “stomach acid” added orange juice to break down the food.
Two students in each group added bananas and crackers to represent a “meal”.
Students enjoyed “chewing the food” as they crumbled ingredients into the bag. They then made the stomach’s “churn” by twisting and squeezing the bag, followed by ringing out the “intestine” to catch the “nutrients” and finally, pushing the “waste” out of the bottom of their cups.

These Champions learned a lot while they also had a ton of fun!
