Grade 3 Science department Unit 6: People and resources Lesson 1: What Are Some Natural Resources? Science Words Say each word quietly to yourself. Then read the meaning. Read the tip to help you remember. natural resource [NACH•er•uhl REE•sawrs] something that comes from nature that people use Resource contains the word source. A source is the place where something begins. Resources are sources of materials needed for making things, such as soap and paper. nonrenewable resource [nahn•rih•NOO•uh•buhl REE•sawrs] a natural resource that can be used up Nonrenewable has four parts: non- re- -new- -able. Nonrenewable and not begin the same way. A nonrenewable resource is not renewable. renewable resource [rih•NOO•uh•buhl REE•sawrs] a resource that can be replaced easily Renewable has three parts: re- -new- -able. Renew and redo begin the same way. When you redo something, you do it again. A renewable resource is a resource that can be made new again. Solar panels collect the sun’s energy, a renewable resource, to heat this house. Grade 3 Science department What Are Some Natural Resources? fossil fuel [FAHS•uhl FYOO•uhl] fuel that forms over many years from the remains of once-living things You know that a fossil is something that forms over a very long period of time. A fossil fuel is a fuel that forms from fossils. conservation [kahn•ser•VAY•shuhn] saving resources by using them wisely If you were in a desert, you would want to make your water last as long as possible. To do that, you would be careful not to spill it. You would use it wisely. You would conserve it. Conservation and conserve are in the same word family. Conservation is conserving our natural resources so they last as long as possible. pollution [puh•LOO•shyhn] harmful substances in the environment Pollution and poison begin with the same sound. Pollution poisons the environment by making it harmful to living things. These pictures show different kinds of pollution. Grade 3 Science department What Are Some Natural Resources? Science Concepts Read the Ideas more than once. Do your best to remember them. 1. Water, soil, and air are important natural resources. 2. Trees are a renewable resource used to make paper and wood products. 3. Coal, oil, and natural gas are nonrenewable resources called fossil fuels. 4. Fossil fuels are used to produce energy, including electricity. 5. Conservation can help make fossil fuels last longer. 6. Products like clothes, toys, and computers are from natural resources. 7. Energy from the sun and the wind are renewable energy resources. 8. Smoke, chemicals, and garbage cause air and land pollution. 9. Burning fossil fuels in cars and burning coal for energy causes pollution. 10. The “3 Rs” –reduce, reuse, recycle–can help you use resources carefully.
