Directions 1. Use the instructional model to show students where they are in the course of the unit. Show slide 2 of the 5.4 Strategies for Lowering Carbon Emissions PPT 2. Introduce the lesson. Display slide 3 of the PPT. Tell students that they will be thinking about how to lower carbon emissions. 3. Draw a class representation. Display slide 4 of the PPT. Have a class discussion about how walking or riding a bike would reduce carbon emissions. Work as a class to draw a representation of this on the board. 4. Pass out the strategy cards. Display slide 5 of the PPT. Give each student one of the 5.4 Strategy Cards. In groups of four, have students discuss how the strategies in these cards would lead to lower carbon emissions. Give them 15 minutes to draw a representation on chart paper of how one of the strategies on their cards would reduce carbon emissions. 5. Have a gallery walk of representations. Display slide 6 of the PPT. Display the representations around the room. Have students walk around the room and look at each of the representations. Ask students to discuss how each representation shows how the strategy would reduce carbon emissions. Also, have students discuss how the strategies are similar and different with regards to how they lower carbon emissions. Display slide 7 of the PPT. Have a full class discussion about which of the strategies students would be willing and able to do. 6. Have a class discussion about larger scale strategies. Show slide 8 of the PPT. Tell students that the strategy cards they just read were mainly things they could do as individuals. However, solving climate change will take cooperation from communities, governments, organizations, and countries around the planet. Tell students to consider the list on the board and also the strategies they have on their cards and brainstorm about actions that society could take together to work for bigger change. Give students 1-2 minutes to think to themselves. Record their ideas on the PPT slide. Also, ask them why is important to adopt some of these strategies and how these strategies can be implemented in their communities at a larger scale. 7. Have a discussion to complete the Learning Tracking Tool for this activity. Show Slide 9 of the 5.4 Strategies for Lowering Carbon Emissions PPT. Have students take out their Learning Tracking Tool for Human Energy Systems from the previous lesson. Have students write the activity name in the first column, "5.4 Strategies for Lowering Carbon Emissions." Have a class discussion about what students figured out during the activity that will help them in answering the lesson driving questions: What causes the annual cycle: CO2 concentrations in Hawaii to go down every summer and up every winter? What causes the long-term trend: CO2 concentrations to go up every year? How can we predict what will happen to CO2 concentrations in the future? When you come to consensus as a class, have students record the answer in the second column of the tool. Have a class discussion about what students are wondering now that will help them move towards answering the unit driving question. Have students record the questions in the third column of the tool. Have students keep their Learning Tracking Tool for future activities. Example Learning Tracking Tool Activity What We Figured Out What We are Asking Now 5.4 Strategies for Lowering Carbon Emissions Our lifestyles contribute to CO2 emissions in many ways. What does increasing CO2 in the atmosphere mean for the future of our planet?
