Trade-in or Trade-off: Energy Alternatives - Grade 11
Ohio Standards
Connection:
Science and
Technology
Benchmark A
Predict how human
choices today will
determine the quality
and quantity of life on
Earth.
Indicator 6
Research sources of
energy beyond
traditional fuels and the
advantages,
disadvantages and tradeoffs society must
consider when using
alternative sources (e.g.,
biomass, solar, hybrid
engines, wind and fuel
cells).
Lesson Summary:
In this lesson the students will review non-renewable
(traditional) and renewable (alternative) energy resources
and examine the trade-offs associated with each type. In
groups of two or three, they will select and research an
alternative resource, an application of that resource, and
then present their findings to the class in an oral
presentation using a visual (poster).
Estimated Duration: Two hours
Commentary:
Students will develop an understanding of the availability of
their alternative energy source, how it works, the
environmental and societal impact, and its application in the
real world. They will also critically examine issues having
to do with their particular energy production or usage and
formulate an approach to making decisions about their
future energy usage and consumption. Upon completion of
all of the presentations, posters will be prominently
displayed so that the connectedness of their products can be
viewed and examined. As a final step, each student will
write a reflective essay and complete a self-evaluation of
their performance.
Pre-Assessment:
 Print questions found in Attachment A, PreAssessment, and distribute to students.
 Direct students to answer the questions provided.
Scoring Guidelines:
See Attachment B, Pre-Assessment Scoring Guidelines, to
assess student responses.

Post-Assessment:
 Evaluate students based on their initial journal writing responses, thoughtful participation
in class discussions, thorough and accurate research and presentation of information
about their topic, creation of a research-based poster, and completion of a reflective essay
describing how their selected resource findings affected them personally. OR
 Evaluate each student’s reflective essay based on EITHER:
a. The law of conservation of energy: OR
b. The following quote by science fiction writer Isaac Asimov:
"The law of conservation of energy tells us that we can't get something for nothing but
we refuse to believe it."
Scoring Guidelines:
See Attachment C, Post-Assessment Scoring Guidelines, to assess student responses.
Instructional Procedures:
1. Have the students reflect in their journal ways they use different energy sources to
produce electricity in a typical day.
2. Have them identify those activities that are dependent upon non-renewable resources
(i.e., fossil fuels such as coal, natural gas and oil).
3. Have students select one of these daily activities and suggest how they would use an
alternative resource such as solar power, wind, etc., instead of a fossil fuel.
4. After the students have completed their journal writing, have some students share their
suggestions with the class.
5. Follow up by a class/group discussion of the following questions:
 Where does each non-renewable energy source originate?
 Are public lands impacted by these resources?
 What are some examples of alternative renewable energy resources?
 Speculate how renewable energy resources can be used instead of fossil fuels.
 Why are we largely dependent on fossil fuel energy sources despite the feasibility of
renewable energy sources?
 What prevents or discourages consumers from using alternative energy sources?
6. Divide the class into small groups of two or three students. Assign each group one type of
alternative energy power source.
7. Distribute copies of Attachment D, Research Guidelines.
8. Give students time in and out of class to gather information about their energy source.
Instructional Tip:
As students gain and comprehend this new knowledge, try to have them recognize any biases
in their own thinking or on the part of the authors they have read.
9. Have groups give a 10-15 minute oral presentation using a poster as a visual. After all the
presentations are completed the students are to make a prediction about what will be the
world's major source of energy a hundred years from now. Evidence should be shown
that their alternative energy source could offer a viable alternative to the more hazardous
2
Trade-in or Trade-off: Energy Alternatives - Grade 11
and/or less plentiful sources.
Instructional Tip:
If time does not permit group presentations, do a gallery walk instead. Display all posters and
allow students to learn from each other’s work.
10. Using the criteria in the evaluation rubric, have students assess their own performance.
Ask students to provide details in support of their personal assessment.
Differentiated Instructional Support:
Instruction is differentiated according to learner needs, to help all learners either meet the
intent of the specified indicator(s) or, if the indicator is already met, to advance beyond the
specified indicator(s).
 Provide students with a copy of their summative assessment tasks.
 Provide students with a concept map to organize and keep track of important terms and
definitions.
 Provide students with research strategies and a list of sample topic suggestions.
Extensions:
 Conduct a similar research project investigating what methods people used in the past in
order to meet their energy needs.
 Investigate significant changes in the availability of renewable resources due to global
warming.
 Design a cost/benefits and maintenance/disposal analysis of a resource application (e.g.
windmill farms).
Homework Options and Home Connections:
Have students ask family and friends about their daily energy usage. This information could
be used as a consideration in their predictions about energy usage in the future.
Materials and Resources:
The inclusion of a specific resource in any lesson formulated by the Ohio Department of
Education should not be interpreted as an endorsement of that particular resource, or any of
its contents, by the Ohio Department of Education. The Ohio Department of Education does
not endorse any particular resource. The Web addresses listed are for a given site’s main
page, therefore, it may be necessary to search within that site to find the specific information
required for a given lesson. Please note that information published on the Internet changes
over time, therefore the links provided may no longer contain the specific information related
to a given lesson. Teachers are advised to preview all sites before using them with students.
For the teacher:
Textbooks and reference materials such as government reports and
scientific journals, and the Internet.
For the students: Poster board, markers, pens.

Attachment B
Pre-Assessment Scoring Guide
The concept map provided is based on current scientific knowledge. Nuclear energy used
today is considered nonrenewable. However, breeder reactors are a renewable resource
because non-fissionable fuel is turned into fissionable fuel. In other words, more fuel is
produced than consumed.
