Electrical Pathways

Concept:

Electricity is generated in a variety of ways. Most of these ways involve a turbine turning a generator to make electricity.

Objective: Students will:

• Recognize similarities in generation of electricity from many different producers – solar, fossil fuels, wind, hydroelectric, geothermal, and nuclear.

State Standards:

• ENERGY

Understand energy, its transformations, and interactions with matter.

Compare forms and behaviors of various types of energy.

Distinguish between the forms of energy including heat, chemical, mechanical, and gravitational potential energy.

Time:

10-15 minutes

Materials:

Butcher Paper, Pens or chalkboard, & 10 Electricity Serves Our Community posters.

Procedure:

Display the poster in the classroom several days before the lesson to cultivate curiosity

1. Assign groups of students who’s job it will be to learn various ways electricity serves the community. Give each group a poster.

2. Have each group report on a different pathways to supply a specific segment of the community with electricity. For example one group might start with wind power and trace electricity to the washing machine in a home. You can assign the source and uses to the groups.

3. Discuss the similarities in the production of electricity by fossil fuels, wind, solar, hydroelectric, geothermal and nuclear. Have each group brainstorm a list of devices at school that use electricity. Allow any reasonable response. (i.e., electric pencil sharpener, aquarium, etc.)

4. List these devices on the chalkboard and categorize them according to use, (i.e., electricity used for hearting the building, heating water, lights, motors, in fans and equipment, etc.)

Evaluation

Have students create a poster entitled Ten Tips to Save Energy at School. Students can use their groups’ lists as a springboard for their poster
