LESSON 6: A Problem of DesignTime: 45-90 minutes
Lesson Overview
Over the past few lessons, students have investigated a variety of alternative energy sources that might eventually replace gasoline as the primary fuel for U.S. vehicles. For now, however, the most cost-effective option for fuel-conscious drivers might be a compromise between alternative energy and gasoline: the hybrid gas-electric vehicle. In Lesson 6, students will learn more about the hybrid technology powering some contemporary vehicles. They will close by investigating a variety of future technologies to keep an eye on as the year 2020 approaches.
Lesson Objectives
By the end of this lesson, students should be able to:- Investigate hybrid electric vehicle technology.
- Compare and contrast hybrid electric vehicles with non-hybrid vehicles.
- Explore additional technologies for improving a vehicle's fuel efficiency and eco-friendliness.
- Finalize their vehicle designs for the year 2020.
Lesson Essential Questions
1. How do hybrid electric vehicles work?
2. How are hybrid electric vehicles similar to and different from non-hybrid electric vehicles?
3. What other technologies exist for improving a vehicle's fuel efficiency and eco-friendliness?
4. What kinds of fuel-efficient, eco-friendly vehicles will exist in the year 2020?
