Summary

Posters are provided for several different energy conversion systems. Students are provided with cards that give the name and a description of each of the components in an energy system. They match these with the figures on the diagram. Since the groups look at different systems, they also describe their results to the class to share their knowledge.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Engineering Connection

Energy "systems" developed by engineers are comprised of numerous components that work together to get the energy content of the energy resource converted into a form that is useful to the user and delivered to the customer. All of the components in the system must be carefully designed to work together effectively.

Learning Objectives

After this activity, students should be able to"

  • Identify and describe the parts of an energy system.
  • Identify their respective environmental impacts.

Educational Standards

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Powering the U.S.

This lesson provides students with an overview of the electric power industry in the United States. Students also become familiar with the environmental impacts associated with a variety of energy sources.

Elementary Lesson
Off the Grid

Students learn and discuss the advantages and disadvantages of renewable and non-renewable energy sources. They also learn about our nation's electric power grid and what it means for a residential home to be "off the grid."

Introduction/Motivation

We just learned about energy sources. The systems you looked at were generally one component of an overall energy system that is comprised of many components.

  • Go over the system diagram for one of the systems the class will not be doing. (For example, reviewing coal combustion relating to the sterno/pinwheel combustion demo would be appropriate; see lesson 4.)
  • Indicate that the real-life energy system also includes coal mining and transportation and the electricity distribution grid to get the energy from its real source (coal in the ground) into electricity to power your TV.
  • Instruct the class to keep in mind the environmental impacts of their respective energy source/system during the course of the activity.

Procedure

Before class:

  • Print and cut apart system cards.
  • Print system diagram posters (large poster size format is best) and post around the room. (we laminate them for repeated use in different classes and years)
  • Make copies of the worksheet.
  • Print and cut apart the Energy Systems Environmental Impacts sheet.

With the students:

1. Energy System Diagram Activity

  • Explain that the students will have to match the system component and its description with its location on the diagram they are given.
  • They will also have to draw a block diagram for their system, identifying the starting and ending form and state for each system component.
  • Divide the class into groups of three students each.
  • In most classes, we only used the wind, solar, and hydro diagrams, but other diagrams can also be used.
  • Go around and assist each group as needed.
  • Once all students have figured out their diagrams, have each group present it to the class.They can do the block diagram on the board. Have each group briefly discuss the environmental impacts of their system to the class.
  • (optional) Pass out the completed handouts for each system.

2. Close with overall assessment of what an energy system is and its general attributes (input, output, conversion process, efficiency).

3. Discuss again how this overall lesson on sources can be used for the unit project.

Assessment

Presentations: Have students present their posters to the class and describe the system components, functions and environmental impacts.

Worksheets: Have students turn in their completed worksheets with block flow diagrams showing the energy forms and conversions for each component.
