Material Required:
- A packet of unsweetened
crackers
Procedure:
- Place an unsweetened cracker in your mouth. Chew it thoroughly, but don’t swallow it.
- Continue to chew without swallowing for several minutes. Does the cracker now taste sweet?
This is what happens:
The moisture in your mouth is called saliva which contains chemicals that start to break down the food before it enters your stomach. The cracker has been changed by the action of these chemicals into simple sugars that your body can use for energy, and you can taste this sugar while the cracker is in your mouth.
