  1. Biodiesel: An Alternative Fuel Source Kathyrn Spates, Biology teacher Barbara Jordan High School for Careers Dr. Timothy Jacobs Department of Mechanical Engineering Texas A&M University

  2. DAY ONE Students will take pretest Journal writing: To engage students and check for prior knowledge Class Discussion: To involve them in problem solving and planning Share my E3 experience Discuss group project and class symposium

  3. AN ALTERNATIVE FUEL SOURCE BIODIESEL

  4. Objectives: The learner will Gain an understanding of terminology associated with the lesson Identify and apply techniques that engineers use to solve problems Compare and contrast physical and/or chemical properties of 3 – 5 different biodiesel fuels Evaluate biodiesel as compared to petroleum diesel and other alternative fuels

  5. TAKS and TEKS Objectives • Biology • 1.1A, 1B, 2A, 2B, 2C, 2D, 3B, 3C and 3D • 3.12A • Chemistry • 4.8B • IPC • 4.8E

  6. How do the two fuels differ petroleum diesel vs biodiesel? PETROLEUM DIESEL What is different about the two carbon cycles? Explain WHAT DO YOU THINK THIS SLIDE IS TRYING TO SHOW?

  7. What are some viable ways to address the depletion of the fossil fuel(petroleum) and minimize its environmental effects in the transportation sector? Decrease its usage Improve vehicle performance Use alternative fuels

  8. Why Alternative Fuels Two pieces of legislation: The Clean Air Act Amendments of 1990 (CAAA) and the Energy Policy Act of 1992 (EPACT) led the way towards alternative fuels

  9. CLASS DISCUSSION What specifications would an alternative fuel need to have in relation to the environment? In relation to the vehicle? How do we determine whether the alternative fuels meet these specifications (testing)? Given the constraints in this classroom, what do you propose we do to address what we discussed? How do we go about getting the information we need to address those issues?

  10. ENGINEERS DOING RESEARCH Dr. Sergio Capareda Dr. Ding Zhu Dr. Timothy Jacobs YOU Dr. Mark Holtzapple

  11. My RET ExperienceResearch Experiences for Teachers Mechanical Engineering at its finest I learned about the fundamentals of an internal combustion (IC) engine and the combustion process

  12. Combustion Cycle inside a cylinder

  13. ADVANCED ENGINE RESEARCH LABORATORY • Purpose is advancing energy conversion of internal combustion engines by investigating in-cylinder combustion processes, use of alternative fuels, emission formation processes and after treatment systems

  14. Bridging To The Classroom • The usage of alternative fuels, emphasis on biodiesel • Exhaust emissions of biodiesel as compared to petroleum diesel • The influence biodiesel would have on the carbon cycle

  15. GROUP PROJECT ANDCLASS SYMPOSIUM • Work in teams to investigate petroleum fuel and other alternative fuels in depth and become the class experts on one of them. • Analyze the impact of using the fuel in three major areas: • its long-term availability and the ease of distribution • its impact on emissions, human health, and the environment • its ease of operation, maintenance, and refueling • Each team will be assigned a stakeholder or interest group to represent. They will listen to the presentations and compare and evaluate the fuels from that perspective. • Presentations may take one or more forms: a poster or series of posters, a display board, a video, a PowerPoint presentation, a booklet, or a pamphlet.

  16. DAY 2 WEBQUEST BIODIESEL

  17. Let’s Explore and Learn More Biodiesel WebQuest Working in groups of 3, students will complete the webquest Control right-click with the mouse to activate the websites Fill in the answers as they navigate through the websites Make notes of any links they may want to explore for their project

  18. DAY 3LAB ACTIVITYCOMPARING BIODIESELS

  19. Design a Lab • Design procedures to find the density of the different biodiesels and the viscosity of the biodiesels if given the materials below • Materials provided: • Balance beakers • Timer graduated cylinder • Thermometer graduated pipette • Graph paper • Safety gear: gloves, apron, goggles

  20. Evaluations and Assessment • Students will take post-test • Group projects and presentations will be evaluated using a rubric • Student groups will also self-evaluate themselves
