It’s Only Natural What are natural resources? Unit 3 Lesson 2 Natural Resources It’s Only Natural What are natural resources? A natural resource is any natural material that is used by humans. Natural resources include air, soil, minerals, water, oil, plants, and animals. Earth’s natural resources provide everything needed for life, including energy, water, food, and building materials. Copyright © Houghton Mifflin Harcourt Publishing Company

How can we categorize natural resources? Unit 3 Lesson 2 Natural Resources How can we categorize natural resources? There are many types of natural resources. Some can be replaced more quickly than others. A natural resource may be categorized as a renewable resource or nonrenewable resource. Copyright © Houghton Mifflin Harcourt Publishing Company

How can we categorize natural resources? Unit 3 Lesson 2 Natural Resources How can we categorize natural resources? A renewable resource is a natural resource that can be replaced at the same rate at which it is consumed. Some renewable resources, such as solar energy, are considered inexhaustible resources because they can never be used up. Other renewable resources are not inexhaustible. Trees and crops, for example, must be replanted and regrown. Copyright © Houghton Mifflin Harcourt Publishing Company

How can we categorize natural resources? Unit 3 Lesson 2 Natural Resources How can we categorize natural resources? A nonrenewable resource is a resource that forms at a rate much slower than the rate at which it is consumed. For example, a fossil fuel is a nonrenewable resource formed from the buried remains of plants and animals that lived long ago. Once a nonrenewable resource is used up, humans will have to find other resources to use instead. Copyright © Houghton Mifflin Harcourt Publishing Company

A Material World How do we use material resources? Unit 3 Lesson 2 Natural Resources A Material World How do we use material resources? Natural resources that are used to make objects, food, or drink are called material resources. Material resources can be either renewable or nonrenewable. Material resources come from Earth’s atmosphere, crust, and waters, and from living organisms. Copyright © Houghton Mifflin Harcourt Publishing Company

How do we use material resources? Unit 3 Lesson 2 Natural Resources How do we use material resources? All foods and beverages are made from material resources. Some foods come from plants, which are renewable because farmers can grow more. Other foods come from animals. Various beverages contain water, which is a renewable resource. Copyright © Houghton Mifflin Harcourt Publishing Company

How do we use material resources? Unit 3 Lesson 2 Natural Resources How do we use material resources? Any object you see is made from material resources. Iron, oil, and sand are nonrenewable. If they are used too quickly, they can run out. Rubber, leather, and wood are renewable. The plants and animals that produce them can be managed so that these resources do not run out.

How do we use material resources? Unit 3 Lesson 2 Natural Resources How do we use material resources? Identify some of the material resources used to build a home. Copyright © Houghton Mifflin Harcourt Publishing Company

Change It Up! How do we use energy resources? Unit 3 Lesson 2 Natural Resources Change It Up! How do we use energy resources? Natural resources that are used to generate energy are called energy resources. Energy is often stored in objects or substances. Stored energy is called potential energy. For this energy to be useful, it must be converted to kinetic energy, which is the energy of movement. Copyright © Houghton Mifflin Harcourt Publishing Company

How do everyday objects convert energy? Unit 3 Lesson 2 Natural Resources How do everyday objects convert energy? Energy cannot be created or destroyed. It must be converted to be useful. An electric oven warms food by converting electrical energy to energy as heat. Your body converts the chemical energy in food to kinetic energy and thermal energy.

Power Trip How is electrical energy produced? Unit 3 Lesson 2 Natural Resources Power Trip How is electrical energy produced? In most electrical power plants, an energy source converts potential energy to kinetic energy, causing wheels in a turbine to spin. The spinning wheels cause coils of wire to spin inside a magnet in a generator. The generator converts kinetic energy to electrical energy. Different energy resources can provide the energy for a power plant. Examples include moving wind or water, and burning coal or biofuels. Copyright © Houghton Mifflin Harcourt Publishing Company

How is electrical energy produced? Unit 3 Lesson 2 Natural Resources How is electrical energy produced? Describe the steps by which electricity is generated at a power plant. Copyright © Houghton Mifflin Harcourt Publishing Company

How is electrical energy produced? Unit 3 Lesson 2 Natural Resources How is electrical energy produced? Fuel cells and batteries are other sources of electrical energy. A battery has chemicals inside that convert chemical energy to electrical energy. Fuel cells convert chemical energy from hydrogen to produce electrical energy. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 3 Lesson 1 Earth’s Support of Life Clean Machines Many car companies are introducing vehicles with hydrogen fuel cells, which use chemical reactions to produce electrical energy. The fuel cell removes electrons from hydrogen atoms, and electron movement generates electrical energy. Hydrogen then combines with oxygen to form water. The reaction produces water and excess hydrogen, but no pollutants. Copyright © Houghton Mifflin Harcourt Publishing Company
