Yummy in Your Tummy

You created a simple simulation of carbohydrate digestion as it passes from the mouth and into the stomach.

Crushing the crackers up with orange juice made the crackers turn to liquid.

Be careful when you mush the bag around so it doesn't pop. That would make a bit of a mess. Oops!

Change the type of food you put in the bag. Try using a different juice, or even a different kind of liquid altogether, like water or milk, or things like cleaning products if you have parental supervision.See what happens if you dissolve a cracker or bite of bread on your tongue for a few minutes. What does it taste like?
