Phase	Unit Air Pressure	Unit Plant Roots	Unit CO₂ Reactions
Engagement	1. Answering: What will happen if we blow breath into the inflated balloon? Why do you think so? What will happen if the inflated balloon is released at once? Why do you think so? 2. Blowing breath into the inflated balloon and releasing it, and answering: What happened? How can you explain what was observed?	1. Drawing a complete plant 2. Answering: What did you draw?Why did you draw the plant root like that? How did you know it?	1. Answering: What will happen if we blow breath through a straw into a water bottle? Why do you think so? 2. Blowing breath through a straw into a water bottle and answering: What happened? How can you explain what was observed?
Experience	3. Predicting (Exercise 1): Connect two cylinders with a plastic tube. Discuss with your peers and answer the following questions: a. What will happen if one cylinder is pressed down? b. Why do you think so? 4. Hands-on (Exercise 2): Press one of the connected cylinders down. Discuss in your group answers to the following questions: a. What did you observe? b. How can you explain what was observed? 5. Questioning (Exercise 3): Write down questions or ideas related to the subject matter that you want to discuss.	3. Predicting (Exercise 1): Choose a wild plant in the school garden to observe. Discuss in the group the answers to the following questions: a. What do you think the plant root looks like? Draw it. b. Why do you think so? 4. Hands-on (Exercise 2): Pull out the wild plant in the school garden. Discuss in the group the answers to the following questions: a. What does the plant root look like? Draw it. b. Why does this plant have a root like that? c. What are the functions of the plant root? Why do you think so? 5. Questioning (Exercise 3): Write down questions or ideas related to the subject matter that you want to discuss.	3. Predicting (Exercise 1): Given a Coca Cola bottle and some Mentos. Discuss in your group the answers to the following questions: a. What will happen if all the Mentos are dropped into the coke bottle? b. Why do you think so? 4. Hands-on (Exercise 2): Drop all the Mentos into the coke bottle. Discuss in your group the answers to the following questions: a. What did you observe? b. Why did it happen? 5. Questioning (Exercise 3): Write down questions or ideas related to the subject matter that you want to discuss
Exchange	6. Presenting results to other groups 7. Discussing results with other groups 8. Answering formulated questions related to subject matter	6. Presenting results to other groups 7. Discussing results with other groups 8. Answering formulated questions related to subject matter	6. Presenting results to other groups 7. Discussing results with other groups 8. Answering formulated questions related to subject matter
Follow-up	9. Answering the questions: What did you learn from the lesson today? Can you provide some examples related to air pressure and explain why you think what you do about them?	9. a. Answering questions: What did you learn from the lesson today? Can you provide some examples of root types and explain why you think those plants have such root types? 9.b. Determining type of root for some plants	9. Answering questions: What did you learn from the lesson today? Can you provide some examples of carbon dioxide reaction and explain why you think what you do about them?
