Year 4 - Digestive System

Date: 25th Nov 2025 @ 10:10am

The classroom buzzed with excitement as tables were covered with paper cups, orange juice, zip-lock bags, and a pair of tights (yes, tights!). The children were curious—“Are we really going to make a stomach?”—and that curiosity set the tone for an unforgettable lesson.

Step by step, we built our digestive system model:

• Mouth: We started by breaking up pieces of bread, just like chewing.
• Stomach: The bread went into a zip-lock bag with orange juice (our stomach acid). The children loved squishing the bag to mimic churning!
• Intestines: Then came the tights—our pretend intestines. We squeezed the mixture through, watching the liquid drip out, representing nutrients being absorbed.

The reactions were priceless:
“Eww, that’s gross!”
“Wow, so that’s how food gets broken down!”
