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. 2 / 20 Why is heat important for life on Earth? To melt snow and ice To help animals stay warm and plants grow To make campfires more enjoyable 3 / 20 What is a natural type of convection? 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. 4 / 20 What is an insulator? Any material that allows heat (or electricity) to move through it easily. 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. 5 / 20 How does convection help us feel warm around the campfire? Convection creates sparks for the fire. Warm air rises, carrying heat with it. The fire gets bigger when warm air rises. The logs burn faster because of hot air. 6 / 20 What does fire give off that makes us feel warm? Wind energy Heat energy Light energy Sound energy 7 / 20 What is conduction? 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 from direct contact. The movement of energy by waves. 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 are examples of materials that transfer heat well? Styrofoam Iron Gold Steel 10 / 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. 11 / 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. Any material that allows heat (or electricity) to move through it easily. The energy of moving particles. 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 How does a spark help start a fire? It provides the air It provides the oxygen It provides the initial heat It provides the fuel 14 / 20 What is radiation? The movement of energy by waves. 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. 15 / 20 What is the difference between conduction and radiation? Conduction requires touching something hot, radiation doesn't. Both answers are correct. Conduction is faster, radiation is slower. 16 / 20 What are the three major types of heat transfer? Convection, Conduction, Nuclear Convection, Conduction, Radiation Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction 17 / 20 What is a natural type of conduction? 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. 18 / 20 What three things does fire need to burn? Fuel, oxygen and heat Fuel, water and oxygen Paper, sticks and lighter Fuel, water and paper 19 / 20 How does heat travel from a mug of hot tea to your hands? By radiation By convection By combustion By conduction 20 / 20 What is the narrator's main point in this story? To show the importance of spending time with dad To teach how to build a campfire To explain how fire and heat work together Your score is 0% Restart quiz Go to the Quizzes Page
