3. 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

4. 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
