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