Slide 2 Lesson 1 What Energy Is Slide 3 Energy is the ability to cause change. Energy allows movement in the world. Slide 4 The energy an object has because of where it is or its shape. Slide 5 Kinetic energy is the energy of motion. Any moving object has kinetic energy. Slide 6 Electricity is a form of energy that people make by using other kinds of energy found in nature such as wind, moving water, oil, or coal. Slide 7 All living organisms store energy. When they die, their bodies are slowly buried by soil and rocks. Over millions of years, some of this material may be pressed together until it turns into fuel, like oil or coal. Slide 8 Hibernation is a state of reduced metabolic activity and body temperature used by certain mammals as an adaptation to winter weather. Slide 9 Slide 10 People can store energy. You an store energy in a battery. Slide 11 Light and sound are form of energy that move. Slide 12 Light moves from the sun to Earth or around the room from a light source. Slide 13 Sound moves from our mouths to our friends ears, from the radio or television to our ears. Slide 14 Light moves as an up and down wave. Slide 15 Sound moves as a back and forth wave. Slide 16 Vibrate means to move back and forth quickly. Slide 17 The path the electricity follows from the battery, through the bulb and back again is called a circuit. Slide 18 Heat and light Slide 19 All living things depend on sunlight, but the appliances and machines we use require another kind of energy: electricity Slide 20 Energy from sunlight is converted by food by plants and then eaten by animals. Dead organisms (mostly plants or plantlike organisms) form fossil fuels which can be burned to make electricity. Slide 21 It changes form. First it is light and heat energy. Then it is food energy. Then it is fuel energy. Then it is electric energy. Both machines and living things can change energy into other forms. Slide 22 Energy of motion produces heat. This heat warms your body.
