Have you ever lost power at home? Did you miss not having electricity? What did you miss? Were you sad that you couldn t listen to music or watch TV? Was it hot because the air conditioner didn t work? Was it difficult to cook dinner? Did things just not work right? We rely on electricity at home and at school to provide light, air conditioning, media (TV, music players, computers, etc.), and power for our appliances to cook and clean. Have you ever run out of gas while driving with your family in the car? A car must have fuel in order to travel down the road and get you where you want to go. We rely on sources of energy to be able to do the things we do every day. When we run out of gas or the electricity goes out, we suddenly realize how important forms of energy are to us. Talk about these questions in your group: Where do we get the resources for fuel energy? What are renewable and nonrenewable resources that we use? What are differences between renewable and nonrenewable resources? Big Idea 6 Part II 159

2 Resource Activity: What Energy Resources Do I Use? (SC.4.E.6.3) List the many different ways you used energy resources this morning to get ready for school. Record your responses in the chart below. When you have finished your energy search, share your answers with your group As you can see from your list, we use energy for many things in our lives. In fact, we probably don t think much about what would happen if we didn t have energy resources to make electricity so that we could keep our food cold, watch TV, and play music. Renewable and Nonrenewable Resources (SC.4.E.6.3) A natural resource is something found in nature that is valuable to humans. Natural resources include a region s minerals, forests, wildlife, and water. We have to limit the use of many of these resources because they cannot be replaced as quickly as we use them. The resources that we use can be classified into two different types renewable and nonrenewable resources. Renewable resources can be used without running out because they are constantly replaced. Renewable resources that are used for energy include the Sun for solar energy, wind for wind energy, and water for hydropower energy. Nonrenewable resources are resources that we are using up more quickly than they can be replaced. Examples of nonrenewable resources that are used for energy include oil, natural gas, and coal, which are called fossil fuels. Fossil fuels are made of dead plants and animals. They have been formed over millions and millions of years by pressure and heat within the Earth. We use fossil fuels to make electricity. Nuclear energy is another example of a nonrenewable resource. Nuclear energy produces electricity and is produced from special types of minerals that are in limited supply, making it nonrenewable. Big Idea 6 Part II 160

3 Energy Activity: How Much Energy Is Used In The U.S.? Nonrenewable Percent of Energy Used Oil 38% Natural Gas 26% Coal 21% Nuclear Energy 9% Renewable Percent of Energy Used Hydropower 3% Solar less than 1% Wind 1% Geothermal less than 1% 1. List all of the renewable energy resources found in the table. Explain why these resources are renewable. Support your explanation with evidence. Big Idea 6 Part II 161

4 2. List all of the nonrenewable energy resources found in the table. Explain why these resources are nonrenewable. Support your explanation with evidence. 3. Using the table, identify which energy resource(s) is/are used the most in the U.S. 4. What percent of the energy we use is renewable? What percent of the energy we use is nonrenewable? 5. What are the advantages of using renewable energy resources? Describe the effect of using more nonrenewable than renewable resources. 6. One of Florida s major renewable resources is solar energy. Why is Florida such a good location for the use of solar energy? Big Idea 6 Part II 162

5 The resources you just learned about are used to make energy, but what about resources that aren t used for energy? Florida has many natural resources. Some of these resources are nonrenewable like limestone (a type of sedimentary rock used for building), silicon (a mineral used to make microchips for technology), and phosphate (a nutrient used in fertilizers and oil). In addition, Florida has an abundant amount of renewable resources such as the Sun, wind, water for agriculture and drinking, and fisheries for food. Can you think of any other natural resources found in Florida? Make a list. Among the natural resources on your list, which are renewable? Explain your reasoning. Among the natural resources on your list, which are nonrenewable? Explain your reasoning. Big Idea 6 Part II 163

6 Resources can be classified into two different types renewable and nonrenewable resources. Renewable resources can be used over and over again without running out. Renewable resources used for energy include solar energy from the Sun, wind energy from the wind, geothermal energy from the inside of the Earth, and hydropower from moving water. Nonrenewable resources are resources that are being used more quickly than they can be replaced. Examples of nonrenewable resources used for energy include oil, coal, natural gas, and nuclear energy. Oil, coal, and natural gas are called fossil fuels because they are made of dead plants and animals. They have been formed over millions and millions of years by pressure and heat within the Earth. We use fossil fuels and nuclear power to make electricity. You also learned that Florida has many natural resources including wood, limestone, water, sun, oil, wind, silicon, and phosphate. Some of these resources are renewable and others are nonrenewable. These resources are used not only by the people in Florida, but by people all over the country. The graphic below shows some of the examples of renewable and nonrenewable resources that we can use for energy. Big Idea 6 Part II 164
