Green Up and Go offers students a real world opportunity to discover and understand principles of physics, engineering, design and green-clean technologies. From electric cars to wind farms our world is driven by innovations that come to life through the marriage of science and engineering. How do we prepare students to successfully navigate these two worlds? Green Up and Go offers students a real world opportunity to discover and understand principles of physics, engineering, design and green-clean technologies. Students, working individually and in teams, participate in a series of hands‑on experimental projects such as building wind generators and personal transportation devices to explore both alternative and traditional energy sources and transportation. The projects provide a foundation for data collection, analysis, reflection, presentations and technical writing skills. Through these experiences students hone critical thinking, communication, collaboration, creativity and Career Technical Education skills while learning key physics, engineering, and design concepts. Students will maintain an engineering journal throughout the year long course. It will contain lab write-ups, diagrams and all other assignments. This year long UC-approved Laboratory Science (D) course combines elements of physics, engineering and green technology to prepare students for success in college science and engineering as well as careers that can contribute to a greener environment for us all.
Unit 1 : Engineering Engines: What They Are and How They Work
Unit 1 Description
Essential Question: How do we build a greener engine?
- What are the functional characteristics of a variety of currently existing engines?
- How can energy be converted into motion?
- Which characteristics of an engine can we modify to make it “greener”?
Physics Concepts Covered: The laws of Thermodynamics, efficiency, Charles’ Law, Boyle’s Law, Combined Gas Law, Pascal’s Principle, States of Matter.
This first unit is used as an introduction to the course by defining the critical steps of the scientific process and engineering design. Moreover, norms for team work, collegial cooperation, and professional communication are introduced. Through research and analysis, students, working in small teams, discover the many types of engines that exist, how they work, and how energy is used, through thermodynamics and the gas laws. Teams learn the history and design development of types of engines (devices that transmit motion), i.e., simple internal combustion, external combustion, turbine, and ones using alternative energy sources. Students present these findings to class. By manipulating variables such as volume, pressure and temperature in a virtual simulator, students collect and analyze data to describe the relationship between these variables as they relate to the motion of the gas particles in various engines. This connects the volume and pressure to thermodynamics. Students in their teams design 3-D models of their engines, report, through papers and oral presentations their engine research and any analysis of the continuing value of that type of engine. Students learn design and drafting techniques as they draw their 3-D models of their engines. Subsequently, teams are challenged to create their 3-Dimensional model using materials available in the classroom, and explore ways of using green technology to reduce environmental impact. Class discussion will cover the future of various types of engines, their continued evolution, and new concepts. Using teamwork, critical thinking, problem solving, imagination, and inquiry, teams analyze their 3-D model engine design to determine how the engine could be made to work, then write and present to the class a technical paper.
Note: In each unit, labs addressing research and construction of models emphasize the physics and CTE concepts involved, while alerting students to the environmental impact and possible solutions to green needs. Students maintain an Engineering Journal throughout the course to record all research, results, data acquired, team activities, and building projects.
