Science: Building the digestive system

As part of our Identity theme, we're learning about the different human body systems during our Science classes with Lisa. Check out her recent blog entry to see how we're learning about the digestive system!

Measuring and recording the lengths of our innards

If we could stretch our digestive systems out, they'd be about this long (and much bigger and messier).
In addition to the yarn models, we created models of our stomachs using plastic bags, complete with juices to replicate the conditions inside of them. We inserted torn up ("chewed") bread and corn, then spent some time mashing the food up to observe the results. It was both interesting and gross!
