1. DO NOW Date: 12/5 Q: How are large molecules broken down during digestion for the body to use? Describe the following as a chemical or physical change? 1)Food being chewed by teeth 2)Food being broken down by the muscles of the stomach 3)Saliva breaking down food during chewing 4)Stomach acid and enzymes breaking down food in the stomach

2. ESSENTIAL QUESTION: How are large molecules broken down during digestion for the body to use? OBJECTIVES: -“Meet Your Food” to understand the large molecules that you eat. - Complete online simulation to understand how large molecules are broken down during digestion for your body to use.

3. ENGAGE: Why do we eat food? -TURN AND TALK -Be prepared to share

4. EXPLORE: “Meet Your Food” JIGSAW EXPERT GROUPS: A- Report to Table 1/5 Hamburger Patties (Protein) B- Report to Table 2/6 Hamburger Buns (Carbohydrates) C- Report to Table 3/7 Cheese (Fats) D- Report to Table 4/8 Lettuce and Tomato (vitamins/minerals)

5. EXPLORE: EXPERT GROUPS: Read the information assigned to your group. Prepare to share your information. 1)What large molecules are broken down when you eat your assigned food? 2)Where is it digested in the digestive system? 3)What smaller molecules are formed when the large molecule breaks down?

6. EXPLORE: Move back to your table group BUILD YOUR HAMBURGER: -Show your Hamburger Part to your table group -Share the molecules on the back -Place your Hamburger Part in the Center of the table and share your information (LETTUCE< PATTY< CHEESE< BUN)

7. EXPLAIN: Digestion Online Simulation You and a partner will use the online simulation to complete the “Journey Through the Digestive System” Graphic Organizer Voice Level 1 as you work

8. ELABORATE: QUESTION: Can ENZYMES and STOMACH ACID really digest large protein molecules into smaller AMINO acids. PROTEIN DIGESTION LAB: -Read the directions carefully -Complete the pre-lab when your test tubes are set up -Voice Level 2
