  3. Findings and Misconceptions What is carbon? Carbon dioxide is bad air or pollution that comes out of cars. Carbon dioxide is the same as air. Carbon dioxide is a gas, we put gas in our cars. Groups didn’t see the relationship between plants and fossil fuels. A tentative connection was carbon to carbon dioxide.

  4. CO2 into Plants: A Skit • 4 groups connected CO2 to plants. • 3 groups connected CO2 to leaves. Teaching Goals • Carbon is in plants. • Carbon can come from CO2. • Plants use carbon as a building block.

  5. Fossil Fuel Formation • Out of the ten groups, only one group made the connection between plants and fossil fuels. • Carbon was a mystery to many students. • What is carbon? • Is it a gas? • What does it look like?

  6. What happens to the carbon when a plant dies?

  11. Carbon to CO2 to Climate Change Students think: • CO2 comes from people breathing and driving cars • Plants need CO2, but don’t know how much plants use • Climate change will happen in the future Teaching Goals: • Sources of CO2 in the USA • Ability of plants to mediate CO2 in the atmosphere • Effects of climate change on San Francisco

  12. What does burning fossil fuels do to the carbon? CO2 Carbon CO2 Carbon

  13. How do Americans contribute to CO2 in the air? Businesses Factories, construction, mining, restaurants,... Homes Lights, electricity, heating, hot water… Population People exhaling CO2 as they breathe… Transportation Cars, trucks, buses, planes, trains, boats…

  14. 44% Businesses 21% Homes 2% Population 33% Transportation

  15. What absorbs CO2 from the air? CO2 CO2 ? CO2 Do the plants absorb all the CO2?

  16. Do America’s forests absorb all the CO2 that Americans produce? Population 50,552 million tons 18% Forest Uptake Homes Businesses Transportation 72% Leftover

  17. What happens to the extra CO2 in the air? CO2 CO2 CO2 The extra carbon dioxide stays in the atmosphere. CO2

  18. When there is more CO2, what happens to the atmosphere?

  19. What does the extra carbon dioxide do? More CO2 = Fever Less CO2 = Healthy 57°F 98.6°F 58.4°F 100°F

  20. Does excess CO2 affect San Francisco? Now Future San Francisco Zoo floods Piers closed already (ref?) 475,000 people in California affected by coastal flooding

  21. Energy is a big cause of CO2 emissions

  22. Survey • Non-divisible behaviors. • Single step • Required to change a person’s behavior • Positive reinforcement • Unlikely to choose actions that they feel they have no control over or interest in. • Understanding what resources are available to students that are essential for doing these behaviors.
