Summary

A large part of engineering involves presenting products, concepts, and proposals to others in order to gain approval, funding, contracts, etc. Through this activity, students' presentation skills are fine tuned while they independently investigate one type of power production to meet the needs of their region of choice. Students also learn problem solving skills while examining the advantages and disadvantages of particular methods of power generation.
This engineering curriculum meets Next Generation Science Standards (NGSS).

Engineering Connection

Understanding energy issues is an important part of engineering. Engineers must fully understand the pertinent science concepts and be able to professionally explain technological concepts in simple terms or in a depth of complexity suitable for the audience.

Learning Objectives

After this lesson, students should be able to:

  • Name different sources of power generation and describe how they work.
  • List the pros and cons of each method and give real-world examples.
  • Describe the long-term financial costs/benefits of each power source presented.

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.

This activity focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts
Define a design problem that can be solved through the development of an object, tool, process or system and includes multiple criteria and constraints, including scientific knowledge that may limit possible solutions.

Alignment agreement:

The more precisely a design task's criteria and constraints can be defined, the more likely it is that the designed solution will be successful. Specification of constraints includes consideration of scientific principles and other relevant knowledge that is likely to limit possible solutions.

Alignment agreement:

All human activity draws on natural resources and has both short and long-term consequences, positive as well as negative, for the health of people and the natural environment.

Alignment agreement:

The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions.

Alignment agreement:

  • New products and systems can be developed to solve problems or to help do things that could not be done without the help of technology. (Grades 6 - 8) More Details

Exploring Nondestructive Evaluation Methods

Students learn about nondestructive testing, the use of the finite element method (systems of equations) and real-world impacts, and then conduct mini-activities to apply Maxwell’s equations, generate currents, create magnetic fields and solve a system of equations. They see the value of NDE and FEM...

Let the Sun Shine!

Students learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity.

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."

High School Lesson
Projections and Coordinates: Turning a 3D Earth into Flatlands

Students learn about projections and coordinates in the geographic sciences that help us to better understand the nature of the Earth and how to describe location.

Pre-Req Knowledge

Prior knowledge of power generation techniques, such as presented in the associated lesson.

Introduction/Motivation

Provide a real-world historical example of a successful business venture leading to the development of a power company. Using a company or region known to students is a good idea. One example, which is close to home for students in North Carolina, is the story of Duke Power's beginnings. Duke Power's historical information is available in the North Carolina Historical Encyclopedia at http://northcarolinahistory.org/encyclopedia/279/entry. These modest beginnings led to the development of a huge power company for the region.

Procedure

  1. Each group represents the interests of an engineering firm specializing in one type of power plant construction.
  2. As a class, have students come up with a list of criteria to consider when choosing a power generation method. Require the list to consist of initial and long term costs, environmental impact, safety, and production capacity to meet the region's soon-to-be-growing needs.
  3. Keep in mind that if for some reason people do not move to the region, the power company will lose money, so public opinion matters.
  4. Explain that the region is a previously undiscovered natural resource gem in that it has everything available that could possibly be needed for implementing any of the technologies. A beautiful river flows in the valley by the town with hot springs in the nearby mountains and abundant sunlight since it is located near the equator with adequate wind. In addition, coal deposits pocket the nearby hills.
  5. Have students brainstorm different energy sources available in the region and identify those sources as renewable or non-renewable resources.
  6. Give the groups 30 minutes to research all aspects of their power plant type.
  7. As students conduct research on the computers, make sure they stay on track by going around and engaging them by group.
  8. Have teams apply what they have learned by organizing the information onto posters to serve as a basis for their presentations. Indicate how much time each group has for its presentation.
  9. Direct students to pay special attention to which natural resource provides the energy, as well as pros and cons associated with tapping the energy from that resource.
  10. Have students make their presentations.
  11. Moderates a class discussion of each proposal, concluding with a class vote on which method to use for the community.

Vocabulary/Definitions

energy: Measurement of the ability of a system to do work.

fuel cell: A device that directly transforms chemical energy, usually hydrogen and oxygen, into electricity without combustion.

non-renewable resource:: Resources that cannot be regenerated as quickly as we use them. In other words, resources that are disappearing and cannot be replenished.

photovoltaic cell: A device that directly transforms light radiation into electricity.

power: Measure of amount of energy being used or generated per unit of time (energy/time).

renewable resource: Resources that are inexhaustible or replaceable by continuously replenished supply.

turbine: A device that produces electricity through the action of fast moving liquid, steam or gas.

Assessment

Presentations/Posters: Student teams prepare posters and make presentations to summarize their specific research and summarize it briefly so the audience (of their peers) understands it. Assess their presentations and posters for accuracy of content, logic and clarity.
