Title of Lesson: Alternative Energy Sources
School: Culver City High School
Grade Level: 10 (9-12)
Students will learn about alternative energy sources, including solar power, wind power, and hydrogen fuel cells. A brief demonstration describing the background, advantages and disadvantages of each energy source is presented. Students will experiment with each energy source using hand-on models.
In what way is your lesson/activity inquiry-based?
The activity is mainly inquiry based. Students, with minimal instruction, are to investigate the devices (windmill, solar cell, and fuel cell car) and come up with theories to explain the underlying the mechanism. Students were able to elucidate the mechanism after a brief period of investigation and guided questions.
1 period – 55 minutes
6 students/per group
Cost to implement:
Wind energy power kit - $50 each
Fuel cell car kit - $60 each
Renewable Energy Kit - $150 each
After this lesson, students should be able to:
Explain the specific mechanism of energy transformation for each of the energy sources. Furthermore, students will be informed of the need to develop alternative energy sources and their wide-ranging impact.
Introduction / Motivation:
Students are asked to draw how they think solar, wind, and hydrogen fuel cells are used as energy sources. Students will then be provided with a brief background of each energy source. Hands-on demonstration materials are provided at stations for the students to investigate how energy is converted from one form to another. Students will then be asked to refine their original drawings of each of the energy sources after the discussion.
See above. For the hands-on portion, students were divided up into groups, and asked to move between stations where the following materials were provided: 1) Wind power, 2) Solar power, and 3) Hydrogen Fuel Cells (cars). Students could stay in classroom or go outside with the materials.
1) 4 x Hydrogen fuel cell car kits (Horizon Fuel Cell Technologies, FCJJ-11)
2) 1 x Wind energy power kit (Thames & Kosmos Wind Power, Renewable Energy Science Kit)
3) 1 x Renewal Energy Kit (Horizon Fuel Cell Technologies, FCJJ-27)
4) Small motors with pinwheels attached, and alligator clips to attach to solar panels

Use kits according to instructions.
Students will be asked to refine their drawings after the discussion and to propose which energy source they feel to be the most promising.

List CA Science Standards addressed:
Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept:
a. Students know energy comes from the Sun to Earth in the form of light.
b. Students know sources of stored energy take many forms, such as food, fuel, and batteries.
c. Students know machines and living things convert stored energy to motion and heat.
Lesson Implementation Comments
How did the lesson or elements of the lesson work as desired?
Students were able to determine the specific mechanism of energy transformation for each of the energy sources.
How did the lesson or elements of the lesson not work as desired?
In periods one and two, the solar cell did not function due to the clouds.
What needs to be done or was already done to revise the lesson to make it more effective?
The lesson was quite effective.
Other comments about this lesson include….
The lesson was a good mix of chemistry and environmental sciences. Students were engaged and participated in the discussions.
