III. TEACHING PROCEDURE/METHODOLOGY
Slide 3: If you were listening closely as your classmates were reading about energy, you might have heard the two major categories of energy resources. Does anyone know what they are?The two categories are nonrenewable and renewable resources.
Slide 4: Can anyone name a renewable resource?
Slide 5: Solar energy is a renewable resource that can create heat or hot water by using solar panels.
Slide 6: Solar panels can be attached to rooftops, to lamp posts, or even to golf carts to create energy to run the lights or the engine. (Show the solar panel and how it powers the fan).
Slide 7: What is another renewable resource? (Hint: There is an excellent example of this type of renewable resource at Yellowstone National Park.) ‡ The type of energy we get from the heat within the earth is called geothermal energy, geo- meaning earth and thermal meaning heat. Geothermal energy can be used to heat water or to produce electricity by steam.
Slide 8: Geothermal energy is clean energy. It doesn’t produce smoky, toxic emissions.
Slide 9: Wind is another type of renewable energy. The blades on this wind turbine spin, and electricity is created.
Slide 10: This wind turbine might look familiar, because it’s designed like the old fashioned windmills. Windmills used the wind to turn their blades, and the energy that was created was used to grind grains.
Slide 11: Curecanti National Recreation Area, where we work, is a popular place to boat and fish during the summer time. Who knows how the lakes relate to the topic of energy? The lakes, or reservoirs were created when dams were built on the Gunnison River. The dams produce hydroelectric energy.
Slide 12: Each dam has a power plant, which uses the powerful flow of water to produce electricity. The electricity is then transferred through power lines to your house, school, shops, and other places that use electricity.
Slide 13: The dams block the flow of the river, and the water pools up to create large man-made lakes, or reservoirs. The reservoirs are great places to boat, fish, and swim.
Slide 14: Biomass is organic material made from plants and animals. Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. The chemical energy in plants gets passed on to animals and people that eat them. Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist. Some examples of biomass fuels are wood, crops, manure, and some garbage.
Slide 15: When burned, the chemical energy in biomass is released as heat. If you have a fireplace, the wood you burn in it is a biomass fuel. Biomass can also be converted to other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel. Biodiesel is produced from left-over food products like vegetable oils and animal fats. Biomass fuels provide about 3 percent of the energy used in the United States.
Slide 16: Renewable resources are sources of energy that can be replaced and are often pollution free. Even renewable resources must be used wisely; if they are not conserved we will jeopardize the continuous use of these resources.
Slide 17: Nonrenewable resources take thousands and sometimes millions of years to form and are considered limited resources. What are some nonrenewable resources?
Slide 18: Nonrenewable resources such as coal, oil, and natural gas are known as fossil fuels. Does anyone know how fossil fuels are made? They are created by the decay of plant and animal matter over thousands, even millions, of years.
Slide 19: Fossil fuels are used to produce steam for steam engine trains, electricity for homes and businesses, fuel for cars, and heat, for instance in a propane grill.
Slide 20: Uranium is used for nuclear energy. Nuclear power accounts for about 20 percent of the total electricity generated in the United States, about as much as the electricity used in California,Texas and New York, the three states with the most people. In 2003, there were 66 nuclear power plants throughout the United States.
Slide 21: We use energy every single day, for a lot of different reasons. Does anyone know what the most used energy resource for electric power is in the United States today? (If necessary, tell the students that it is one of the fossil fuels). Coal generates more than half of our electricity.
Slide 22: Ask the students how much electric energy they think various resources generate.
Coal: 54.6 %
Natural Gas: 11%
Hydroelectric: 9.4 %
Slide 23: Our non-renewable energy sources will someday run out. That’s why it’s important to look for renewable energy sources and clean energy sources, and to start relying less on non-renewable and more on renewable energy sooner, rather than later.
"It seems as though we have many, many uses for energy. We will have enough energy for all of our demands only if we take care of our resources and use them wisely. What is another word for using resources wisely? This is called conservation. We need to conserve our energy resources if we are to be able to use them in the future." Have two students come to the front of the room and stand in front of two chairs. Instruct one of the students to step up onto the chair and then step back down over and over, as fast as he or she can without getting hurt. Instruct the other student to step up onto the chair and then step back down, waiting ten seconds before repeating the process. Have students do this for about a minute or until they get tired. "Which student was conserving energy? How could you tell? The student that was waiting ten seconds each time was pacing his or herself. They were conserving energy." Ask the students why it is important to conserve our energy resources (both limited and unlimited).
IV. CHECK FOR STUDENT UNDERSTANDING
Divide the students into four teams, placing a bell at each station. Have students choose a team name that has something to do with energy. "Let's see how much you've learned about energy. I have a list of energy trivia questions. I will read a question, and if you or a teammate knows the answer, ring the bell. Whichever team rings the bell first will get the first chance to answer the question. If the correct answer is given, that team will get one point. You do not lose points for incorrect answers. You may, however, lose points if your team shouts out the answer without ringing in first. If no one answers the question, no one gets a point. When there are five minutes left, we will play a round of 'double jeopardy' where each question is worth two points. Do you have any questions?" Ask questions from the attached energy trivia sheets. Continue this activity for about 15 minutes, or until time is up.

V. GUIDED PRACTICE
VI. INDEPENDENT PRACTICE
Encourage the students to share their ideas of energy conservation with family and friends, and emphasize the importance of putting these ideas to use.
Our non-renewable energy sources will someday run out. That’s why it’s important to look for renewable energy sources and clean energy sources, and to start relying less on non-renewable and more on renewable energy sooner, rather than later. What are some ways that YOU could conserve energy? (Make a list on the board: (may include) walk or ride a bike, rather than asking parents to drive you somewhere; turn off the lights, computer, etc. when you’re finished using them; encourage teachers and parents to install solar panels; take shorter showers-use less hot water).
Even though you’re not old enough to drive a car yet, there are a lot of ways that you can help conserve energy. If we all work at it, our planet will be better off in the long run. Thanks for your participation today. We’ll turn the class back over to your teacher now, and we hope that each of you will visit Curecanti to see a source of hydro-electric energy someday soon.
