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