Understanding Digestion: The Role of Chewing and Chemical Processes in the Mouth
This lesson explores the critical process of digestion that begins in the mouth. By chewing food, such as a cracker, we not only prevent choking but also initiate the breakdown of carbohydrates. The mechanical action of chewing, combined with chemical reactions involving enzymes like amylase, transforms complex starches into simpler sugars. This lesson will include a hypothesis exercise, a data recording activity, and a discussion on the importance of enzymes in digestion, setting the stage for understanding how our bodies absorb nutrients.

Lesson 4 Digestion in Mouth
Getting Started • 1a- Chewing the cracker is important because it breaks the cracker down so that we may not choke. It also enables the food to react with chemicals in mouth. • 1b-Adam’s apple went up, then down.
Purpose-Exploring chemical digestion in mouth • Hypothesis -If, then, because • Reading article-Making it simple • 1. Body cannot use carbohydrates until they are broken into simpler form • 2. Starches are made up chains of simple sugars tat are held together by bonds. • Starch is chewed and acted upon by digestice
Reading article-Making it simple • 1. Body cannot use carbohydrates until they are broken into simpler form • 2. Starches are made up chains of simple sugars tat are held together by bonds. • Starch is chewed and acted upon by digestive enzymes in the mouth and small intestine and link of chains are broken down to simple sugars • These sugars are small to enter the cells
Data • Copy data table • Record the data
Conclusion • Write the conclusion
vocabulary • Enzyme • Amylase • Mechanical digestion • Chemical digestion
