Introduction:

In this unit students will investigate what might cause electrical systems to fail. The students will design solutions to improve the electrical system in the town of Ergstown to prevent blackouts from occurring. Ergstown has a problem with blackouts. During a blackout, all the power in the city goes out. The mayor of Ergstown has enlisted your help to figure out how to prevent all of the blackouts that are happening in his town.

 

 

Task:

Students will learn and investigate about different types of electrical energy and its forms. The students will use an energy conversion simulation to create a system of light and sound to help the town of Ergstown. After the students have learned about different forms of energy and the path of electrical flow, they will write an essay to the Mayor discussing their plan and solution on how to prevent frequent blackouts in Ergstown.

 

 

Process/Resources:

1: Reading About Energy Converters (25 min.) Students revisit the reference book to gather information that may help them come to a better understanding about the function of electrical devices and answer the Investigation Question. Students read about various electrical devices and record their input and output energy forms in their notebooks.

 

2: Energy in Electrical Systems (25 min.)

Using the Energy Conversions Simulation, students create systems with light and sound as output energy forms. Students observe energy input and output graphs as their systems function. This enables students to correlate the amounts of energy entering and leaving the systems in different forms and come to a deeper understanding of the concept of energy conversion. This activity includes an On-the-Fly Assessment to assess studentsí comprehension of the concept of energy conversion.

 

3: Reflecting on Learning (10 min.)

Drawing on the dayís reading and the Sim activities, students reflect on what they have learned thus far about the electrical system and the function of electrical devices as energy converters.

 

4. Discuss the function of the Electrical System

 

5. Students will use what they learned in all previous lessons to write an essay to the Mayor discussing their plan on how to prevent the blackouts in the town of Ergstown.

Essay must include an Introduction, 2 body paragraphs with evidence to support your reasoning for your plan, conclusion, and a diagram of your electrical path to prevent the blackouts.

 

6.† Students will present their solutions to the class once essay is written.
