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