LESSON PLAN: LESSON 2.9 – RENEWABLE AND NON-RENEWABLE ENERGY Page 1 of 10 FORMS OF ENERGY – LESSON PLAN 2.9 Renewable and Non-Renewable Energy This lesson is designed for 3rd – 5th grade students in a variety of school settings (public, private, STEM schools, and home schools) in the seven states served by local power companies and the Tennessee Valley Authority. Community groups (Scouts, 4-H, after school programs, and others) are encouraged to use it as well. This is one lesson from a three-part series designed to give students an age- appropriate, informed view of energy. As their understanding of energy grows, it will enable them to make informed decisions as good citizens or civic leaders. This lesson plan is suitable for all types of educational settings. Each lesson can be adapted to meet a variety of class sizes, student skill levels, and time requirements. Setting Lesson Plan Selections Recommended for Use Smaller class size, higher student ability, and /or longer class length • The “Modeling” Section contains teaching content. • While in class, students can do “Guided Practice,” complete the “Recommended Item(s)” and any additional guided practice items the teacher might select from “Other Resources.” • NOTE: Some lesson plans do and some do not contain “Other Resources.” • At home or on their own in class, students can do “Independent Practice,” complete the “Recommended Item(s)” and any additional independent practice items the teacher selects from “Other Resources” (if provided in the plan). Average class size, student ability, and class length • The “Modeling” Section contains teaching content. • While in class, students complete “Recommended Item(s)” from “Guided Practice” section. • At home or on their own in class, students complete “Recommended Item(s)” from “Independent Practice” section. Larger class size, lower student ability, and/or shorter class length • The “Modeling” Section contains teaching content. • At home or on their own in class, students complete “Recommended Item(s)” from “Independent Practice” section. Electrical Safety Reminder: Teachers should remind students that electricity is dangerous and that an adult should be present when any recommended activities or worksheets are being completed at home. Always obey instructions on warning labels and ensure one has dry hands when touching electronics or appliances. Performance Objectives By the end of this lesson, students will be able to: • Identify, explain, and provide examples of both renewable and non- renewable energy sources. • Discover ways to conserve energy. • Evaluate their families’ use of energy. • Understand the benefits and disadvantages of using renewable resources.

Anticipatory Set (Attention Grabber) Essential Question How can we be sure to never run out of energy? II. Modeling (Concepts to Teach) A natural resource is given by nature and can be used as a source of energy. A renewable natural resource is one that can be renewed, or replenished in a reasonable amount of time (in years or a human-life span), once it has been used. Renewable energy is generated from natural sources (sun, wind, rain, tides, and vegetation) and can be generated again and again when needed. It is generally replenished naturally. For example, trees are a renewable resource because once a tree is removed and used, a new tree can grow in its place. Additional information is available at http://www.tva.gov/renewable/.

Wind Energy – The energy of the wind is transferred to the turbines of the generator and the generator produces electricity. Wind turbines use the momentum of moving air to quietly turn large blades that are attached to the shaft of an efficient electric generator. http://www.tvakids.com/electricity/wind.htm 5. Biomass Energy – Biomass is matter usually thought of as garbage. This matter includes things like leaves, tree branches, leftover crops, wood chips, and bark. It can even include animal manure and old tires. LESSON PLAN: LESSON 2.9 – RENEWABLE AND NON-RENEWABLE ENERGY Page 6 of 10 The biomass is then placed into a furnace and burned, or the methane gas in a liquid or gaseous state from algae or rotting / decomposing materials is captured. The heat generated is used to boil water. The steam from the boiling water is used to turn turbines and generators to produce electricity. A non-renewable natural resource is one that has specific conditions that made them (like fossilized plant matter converting into coal), and can take many generations to reproduce. Sometimes the conditions are not likely to occur again so they are limited in supply and once used cannot be re-generated within a short span of time. Non-renewable sources exist in the form of natural gas, oil, and coal. For example, fossil fuels have been percolating beneath the Earth for hundreds of millions of years, and once they’re gone, they’re going to take millions more years to replenish. Types of Non-Renewable Natural Resources 1. Coal Energy – Coal is the product of millions of years of pressure on organic matter from plants buried underground. According to Energy Information Administration, coal-burning power plants are the number one source of electricity in the U.S., and burning coal is an inexpensive way to generate electricity compared to many renewable sources. However, burning coal produces greenhouse gases, which scientists believe is contributing greatly to global warming. http://www.tvakids.com/electricity/fossil.htm 2. Oil Energy – Crude Oil is referred to as Liquid Petroleum. It is used for gasoline, heating oil, and diesel fuel. In addition, manufacturers utilize oil for such products as plastics and industrial chemicals. 3. Natural Gas Energy – Natural gas reserves often share space with underground oil reserves, so the two REMEMBER List the renewable energy sources. List the non-renewable sources of energy. (Teachers can list these on the board with help from students. Ex. Renewable – solar, wind, etc.) UNDERSTAND Explain the difference between a renewable and a non-renewable energy source. (Class discussion) ANALYZE Categorize a list of sources of energy (water, wind, coal, natural gas, etc.) into the correct categories of renewable and non-renewable energy. (Class discussion) EVALUATE Debate the pros and cons of using non-renewable energy. (Class discussion) CREATE Create a brochure that persuades people in your community to conserve energy. (Teachers instruct students to create a brochure on a piece of paper. http://www.education.com/activity/article/make_a_fun_brochure_fourth/) Coal 39.3% Natural Gas 27.6% Petroleum 7.0% Nuclear 19.5% Hydropower 6.7% Wind 4.2% Other Renewables 2.1% LESSON PLAN: LESSON 2.9 – RENEWABLE AND NON-RENEWABLE ENERGY Page 7 of 10 non-renewable resources are often extracted at the same time. Consumers use it as cooking fuel, to heat houses, and sometimes as vehicle fuel. It is also used to generate 27.6% of the U.S. electricity. It would take many generations, perhaps millions of years, to replenish natural gas. http://www.tvakids.com/electricity/combustion.htm 4. Nuclear Energy – Nuclear energy makes use of Uranium-235, a radioactive chemical naturally found in the earth. This radioactive substance undergoes decay and in the process releases a great deal of heat. The heat is then used to create steam; that steam is used to turn a turbine in a generator. The generator produces the electricity. There are no greenhouse gases released in this process. However, there are radioactive byproducts that must be stored safely because they are an environmental hazard. It is considered a non- renewable form of energy because it takes real manipulation to split an atom. http://www.tvakids.com/electricity/nuclear.htm The above chart shows the percent of electricity generation by energy source. Most power is now generated from coal, natural gas, and nuclear plants. If time permits, teachers can go over each source in the pie chart. III. Checking for Understanding Teachers can ask students these questions to determine understanding of concepts.
