Home Stomach Experiment!

We've been studying physiology this year and its probably one of the boys favorite subjects.  Today we learned about the stomach.  First, we read a book with pictures and talked about how it worked.  Then we drew a picture of the stomach (the boys drew their favorite foods inside the stomach).



Then we really had fun and made our own "stomach" from a plastic bag.  They put in some different foods: bread, cracker, cereal and jelly bean.  We mixed in the "stomach acid" (lemon juice) and they squished it up to act like the stomach breaking down the food.  Here's a video about it:

We'll let the bags sit on the kitchen counter for 24 hrs and see the results of our experiment tomorrow!
