1. Goal: To explain the difference between diffusion and active transport in order understand why these are necessary for absorption of nutrients. Sci7: Tu Mar 22 In Journal Diffusion 1.How do nutrients pass from the digestive system to the circulatory system? 2.What does smell have to do with the digestive system?

2. Sci7: Tu Mar 22 In Journal Diffusion Read “Diffusion & Active Transport” pg. 46-47. & Answer the these questions: 1. Explain what happens when the tea bag is placed in the mug. 2. Explain how the diffusion works in the small intestine. 3. Explain the difference between “diffusion” and “active transport”. 4. What is something that you learned? 5. What questions do you still have about the digestive system?

3. Sci7: Tu Mar 22 Table & Class Acting Diffusion 1. Act out the role of “diffusion” and “active transport”. 2. Table 1,5,6,7 “Diffusion” 3. Table 2,3,4,8 “Active Transport” 4. You can make one large group, or a few smaller groups, 5. Each group must have at least four (4) people. 6. Ten (10) minutes preparation, then present.

4. Goal: To explain the difference between diffusion and active transport in order understand why these are necessary for absorption of nutrients. Sci7: W Mar 23 In Journal Diffusion 1.How do nutrients pass from the digestive system to the circulatory system? 2.What does smell have to do with the digestive system?

5. Sci7: W Mar 23 In Journal Diffusion Complete Inquiry 6.1 on page 42-44. #1-#10. STOP when you get to step #6. We will do Step #6 as a class. Work together with your table groups and help each other to answer the questions. Complete the Lab Worksheet. Turn in Worksheet at the end of class! Goal: To explain the difference between diffusion and active transport in order understand why these are necessary for absorption of nutrients.

6. Sci7: Th Mar 24 Worksheet Diffusion 1. Take the handout on the front table of the “Diffusion and Cell Membranes”. 2. You have 20 minutes to complete this. 3. Think back to the lab we last completed. 4. We will discuss the results as a class. Goal: To explain the difference between diffusion and active transport in order understand why these are necessary for absorption of nutrients.
