Students investigate the history of humankind’s need to develop tools that enhance quality of life and satisfy the need for efficiency. Students quickly discover that survival depends on energy resources throughout history and technology dictates how energy resources are used. Students analyze the trade-offs associated with various energy sources. Students evaluate alternative energy sources, experiment with alternative fuels for cars, conduct an appliance survey, and compare how countries are similar or different in their energy use. As a culminating project, students simulate the process of buying a car using data and statistics that could impact their decision.

View how a variety of student-centered assessments are used in the Energy Innovations Unit Plan. These assessments help students and teachers set goals; monitor student progress; provide feedback; assess thinking, processes, performances, and products; and reflect on learning throughout the learning cycle.
Part I: Presenting the Problem
Have students respond to the Essential Question, What is a quality life? In pairs, have students list factors that contribute to a quality life and rank the factors from most important to least. Ask students to share their rankings within a team of four, and create a new ranking based on team consensus. Have each team report out, and then conduct a class discussion on commonalities among the factors. Guide students to the conclusion that many of the factors relate to energy.
Review with students their knowledge of energy concepts using an energy pre-assessment. Use this assessment to guide the development of lessons on energy concepts appropriate for their level.
Ask students to share what specifically has influenced them and their family to conserve energy and what methods they currently use to conserve energy, if any. Create a poster with the cumulative answers from each class. Post somewhere visible in the classroom.Create a multimedia presentation that contains headlines from major newspapers and magazines around the world that focus on energy topics. Guide students to the realization that energy is a driving force behind many political issues, economic policies, and wars. Conduct an open-ended discussion by asking the Unit Question, How can we use our energy resource responsibly? and the question, Are we using our energy resources wisely? (As an alternative, have students create their own slideshow presentations that highlight major stories and events focusing
on energy.) Have students journal how their decisions about conserving energy could impact their quality of life. Inform students that they will use their journals periodically throughout the unit to reflect on their learning.
Part II: Understanding the Problem
Ask students the Content Question, What are alternative energy sources and how can we use them? Provide background information by assigning the Clean Air Acts activity as homework. This activity explains the history of energy conservation and the impact of alternative energy sources. As an alternative, plan with the social studies teachers to implement this assignment.
Sessions 3 through 7
Divide students equally into eight groups. Assign each group one of the following energy sources:
Explain that each group will prepare a learning center on their assigned energy source from which other groups will learn. Present the project plan, which helps each group organize their learning center. Show students how to use bookmarking systems—such as del.icio.us, Diigo, and Furl—to keep track of Internet research. Hand out research notes template for students to use for their research information.
Hand out the energy source rubric, which explains that students will investigate the technology, advantages/disadvantages, history, environment and economic costs, and application of each energy source. Explain to students that this is the type of information that will be displayed in their learning center. Review with students data analysis methods, such as scatter plots, box plots, linear regression, and histograms. Describe how the data analysis methods might be used in the project. Review various types of data and have students practice identifying the types of data from graphs collected prior to the lesson.
Explain that a brochure can also be used as part of their learning center. Show students the brochure sample. Discuss how the brochure can be improved by adding data analysis methods. Brainstorm, as a class, specific data analysis methods that could be used on this brochure. Encourage students to ask questions that can be answered using data analysis methods.
Tell students that they will also prepare and participate in a debate and try to persuade others why their assigned energy source is the best for society and Earth. Have each group create a poster that displays their data and research, and uses spreadsheet software to help analyze their data to use during the debate. As an extension, show student how to work as a group using the Showing Evidence Tool. Explain how claims are made about an energy source and how information is inserted to back up the claims. Encourage students to access their information from the Showing Evidence workspace during the debate.
During this project, set aside time for whole class experiments on combustion, endothermic/exothermic chemical reactions, particulate concentrations, and conservation of energy to help students gain a better understanding of the general principles and impact of energy. If available, have students use science probeware to collect data and practice representing data graphically.
Hand out the group assessment and have students assess their group process and individual work at a designated point during the work sessions. Hand out the debate checklist to inform groups of the expectations during the debate. This checklist could also be used as a scoring guide during the debate.
Conduct the class debate. Instruct each group to assign a debate leader. Have each group review the debate checklist. Allow time for students to assess their groups again using the group assessment after the debate. Provide time for students to complete another entry in their journals on new learning and insights gained through the activities experienced.
After the debate, allow time for students to walk through each learning center. Hand out the data assignment worksheet that explains how each student will use data analysis methods to culminate the information from each learning center; specifically, students analyze gaseous and particulate pollution, efficiency, production and consumption of each energy source. Use the Content Question, What problems are associated with fossil fuels? as an assessment question. Use the fossil fuel essay checklist to help students understand what information to include in the answer to the question.
Part III: Finding Solutions
Now that students have gained a foundation and global perspective on our world’s energy problems, ask students to brainstorm ways they can be part of the solution as a citizen of this world. Present the Unit Question, How can data and research affect your decisions? Ask students how they decide to buy certain products. Conduct a class discussion defining the methods and procedures currently used by students. Have students share methods their parents might use as well. Emphasize any decision making process that uses data and research.
Show pictures of large cities in which air pollution is prevalent to get students thinking about automobiles and their impact on our environment. Explain to students that they will conduct research on how their quality of life is impacted by two major factors:
Present a mini-lesson on the process of measuring vehicle emissions. Have students take notes in their journals. As homework or an extension, instruct students to find information on how emissions testing and standards vary from state to state as well as by country. Have them investigate five large cities from different countries (such as Mexico City, Cairo, Hong Kong, New York, and Los Angeles) to compare the impact of vehicle emissions on the specific city.
Sessions 11 and 12
If materials are available, plan for whole class experiments on solar and hydrogen vehicles, byproducts of combustion, and emissions.
Show students how to use the Visual Ranking Tool to organize their research and evaluation of the different types of fuels sources for vehicles. Prepare the workspace to include the following factors:
Working in pairs, have students conduct Internet research of the different fuel sources and rank which ones they believe to be the best option for most cars. Explain that students are to list major advantages and disadvantages of each and include their reasoning of their rankings. Show students how to compare their thinking with other pairs in the class. Explain the correlation coefficients and how to interpret the numbers. Allow students time to change their ranking based on new insights gained from their peers. Remind students to use their bookmarking systems to keep track of their Internet sources.
Hand out the alternative fuels checklist to guide students’ thinking during this activity. Provide time for students to add another journal entry on new insights and reflections on their current learning.
Session 14—The Homework Project
Explain to students that they will simulate the process of choosing a vehicle to purchase. Instruct students to first pick two vehicles to compare side by side. One vehicle is their choice but the second vehicle must be a brand new green car. Explain the terminology green car and show examples from Web sites of these types of vehicles, also known as Alternative Fuel Vehicles (AFVs).
Hand out the purchase guide instructions that explain the steps required for this project. Have students use the purchase guide checklist and purchase guide self-assessment to assess their work as well as each other’s work throughout the project. Explain that students will investigate the technology behind the alternative fuel source for the AFV they chose and conduct in-depth research on both vehicles’ emissions and the technologies used in their chosen vehicles. They will use data analysis methods to analyze gaseous and particulate pollution, efficiency, production and consumption, and compare each vehicle’s fuel costs for one year based on their individual commuting situation.
Pass out several consumer magazines and have students observe the structure and data included for the products highlighted. As a class, create an electronic consumer magazine that has all the individual projects compiled into one magazine. This magazine should feature the current technologies of vehicles with the independent data collected from each student.
As an extension, students can apply for extra credit to serve on the editorial staff responsible for putting the magazine together with a cover, table of contents, and unifying structure.
Allow students two weeks to complete this project at home. Midway through the project, provide time in class for students to conference with each other on their progress. Provide another copy of the purchase guide checklist for students to use during their peer conference. Explain that students are to continue writing in their journals during the homework project, including insights and reflections on their learning.
Session 16 (after students have completed the vehicle project)
As a final assessment, ask students to answer the following questions reflecting on the projects they completed during the unit:
Hand out the essay rubric as a guide for students to use while answering the questions.
After the editorial staff has completed the class consumer magazine, post the magazine on a Web site for all students and parents to read.
