Alternative Energy

Driving or Multi-dimensional Question:

Phenomena: Fukushima Diichi Nuclear Power Plant Meltdown

Japan has ceased production of energy for all 34 of its nuclear reactors since the nuclear power plant meltdown and is importing fossil fuels. Because Japan has very few natural resources and is a small country, this is not a sustainable solution. Japan is searching for a solution to help them find a clean, safe and simple alternative energy solution that will meet the demands of a growing population. Students will design a prototype vertical-axis wind turbine applying the concept of energy transformation. They will modify their design blades to convert wind power into mechanical power that produces the most rotations per minute as measured by the voltage, or enough to light an LED bulb. Students will reflect on their design, communicate scientifically and demonstrate their learning in a creative way. They will modify their design by increasing efficiency and power output, while reducing costs and risks.

Unit Summary:

As the world’s population continues to grow exponentially, increasing demands are placed on conventional fossil fuels. In this Project Based Lesson, students will assess conventional and alternative energy systems, and create and design models of wind turbines and solar cars. They will determine the output necessary to meet regional energy needs in the 21st century in a sustainable manner. Students will compare and contrast TVA with Japan and propose a solution to Japan’s need for an alternative energy resource.

Tennessee Academic Standards for Science Connection

Disciplinary Core Idea: Energy Manifests Itself in Multiple Ways, Such as in Motion, Sound, Light and Thermal Energy. Energy is a Quantitative Property of a System that Depends on the Motion and Interactions of Matter and Radiation Within that System.
Science and Engineering Practices: Design a Solution to a Complete Real-World Problem, Based on Scientific Knowledge, Prioritized Criteria and Tradeoff Considerations. Analyze Complex Real-World Problems by Specifying Criteria and Constraints for Success.
Cross Cutting Concepts: Modern Civilizations Depend on Major Technological Systems. Engineers Continuously Modify These Technological Systems by Applying Scientific Knowledge and Engineering Practices to Increase Benefits While Decreasing Costs and Risks.
