To help animals stay warm and plants grow To melt snow and ice To make campfires more enjoyable 2 / 20 What is conduction? The way heat moves through liquids and gases. Any material that allows heat to move through it easily. The movement of heat from one solid to another from direct contact. The movement of energy by waves. 3 / 20 What is radiation? The movement of energy by waves. Any material that allows heat to move through it easily. The way heat moves through liquids and gases. The movement of heat from one solid to another. 4 / 20 How does heat travel from a mug of hot tea to your hands? By convection By radiation By conduction By combustion 5 / 20 What is a natural type of conduction? The sun directly touching the ground to transfer heat. The ground heating the air that is touching the ground. The heat waves from the sun heating up the ground The warm air heated by the ground rising 6 / 20 What is a natural type of convection? The sun directly touching the ground to transfer heat. The heat waves from the sun heating up the ground. The warm air heated by the ground rising. The ground heating the air that is touching the ground. 7 / 20 What is convection? Any material that allows heat to move through it easily. The movement of energy by waves. The way heat moves through liquids and gases. The movement of heat from one solid to another. 8 / 20 How is the sun similar to a fire in terms of heat? They both give off heat through radiation They both need oxygen to burn. They both burn fuel. 9 / 20 How does convection help us feel warm around the campfire? The fire gets bigger when warm air rises. Convection creates sparks for the fire. Warm air rises, carrying heat with it. The logs burn faster because of hot air. 10 / 20 What three things does fire need to burn? Fuel, water and oxygen Fuel, water and paper Fuel, oxygen and heat Paper, sticks and lighter 11 / 20 What is an conductor? Any material that allows heat (or electricity) to move through it easily. Any material that does not allow heat (or sound) to pass through it easily. The energy of moving particles. The tool that is used to measure how hot or cold something is. 12 / 20 Besides conduction, how else can you feel the fire's warmth even if you're not touching it? By smelling the smoke By radiation By seeing the flames 13 / 20 What is an insulator? Any material that allows heat (or electricity) to move through it easily. The tool that is used to measure how hot or cold something is. The energy of moving particles. Any material that does not allow heat (or electricity) to pass through it easily. 14 / 20 What is the difference between conduction and radiation? Conduction is faster, radiation is slower. Conduction requires touching something hot, radiation doesn't. Both answers are correct. 15 / 20 What is a natural type of radiation? The heat waves from the sun heating up the ground The warm air heated by the ground rising The ground heating the air that is touching the ground. The sun directly touching the ground to transfer heat. 16 / 20 What are the three major types of heat transfer? Conduction, Radiation, Chain Reaction Convection, Conduction, Nuclear Convection, Radiation, Atomic Convection, Conduction, Radiation 17 / 20 How does a spark help start a fire? It provides the air It provides the oxygen It provides the fuel It provides the initial heat 18 / 20 What are examples of materials that transfer heat well? Styrofoam Gold Steel Iron 19 / 20 What does fire give off that makes us feel warm? Heat energy Light energy Wind energy Sound energy 20 / 20 What is the narrator's main point in this story? To show the importance of spending time with dad To explain how fire and heat work together To teach how to build a campfire Your score is 0% Restart quiz Go to the Quizzes Page
