Directions: Use the information you have been given to answer questions about: What begins to happen to the food you place in your mouth? 

Level#1

The mouth is the place where digestion begins. Food is broken down into smaller pieces by the teeth. Breaking, crushing, and mashing food are forms of mechanical digestion.

1. What begins in the mouth?





2. What do we use to break food down into smaller pieces in our mouth?





3. How do we mechanically digest food in our mouth?







Level#2

The mouth is the place where digestion begins. Food is broken down into smaller pieces by the teeth. Breaking, crushing, and mashing food are forms of mechanical digestion. An enzyme is a substance that changes the rate of a chemical reaction. When a chemical reaction happens in the digestive system, the process is called chemical digestion.
