Then, answer the following questions: Please write your name and email to receive your certificate. 1 / 20 How does convection help us feel warm around the campfire? The logs burn faster because of hot air. Convection creates sparks for the fire. Warm air rises, carrying heat with it. The fire gets bigger when warm air rises. 2 / 20 How does heat travel from a mug of hot tea to your hands? By radiation By combustion By convection By conduction 3 / 20 What three things does fire need to burn? Paper, sticks and lighter Fuel, water and paper Fuel, oxygen and heat Fuel, water and oxygen 4 / 20 What are the three major types of heat transfer? Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction Convection, Conduction, Nuclear Convection, Conduction, Radiation 5 / 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 6 / 20 How does a spark help start a fire? It provides the oxygen It provides the air It provides the initial heat It provides the fuel 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 heat waves from the sun heating up the ground The warm air heated by the ground rising 8 / 20 What is an conductor? 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 sound) to pass through it easily. 9 / 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. 10 / 20 What is a natural type of convection? The heat waves from the sun heating up the ground. 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. 11 / 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 12 / 20 What are examples of materials that transfer heat well? Gold Iron Steel Styrofoam 13 / 20 What does fire give off that makes us feel warm? Wind energy Light energy Sound energy Heat energy 14 / 20 What is an insulator? The energy of moving particles. 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. Any material that does not allow heat (or electricity) to pass through it easily. 15 / 20 What is a natural type of conduction? The warm air heated by the ground rising The heat waves from the sun heating up the ground The ground heating the air that is touching the ground. The sun directly touching the ground to transfer heat. 16 / 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 17 / 20 What is convection? 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. The way heat moves through liquids and gases. 18 / 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. 19 / 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. 20 / 20 Why is heat important for life on Earth? To help animals stay warm and plants grow To make campfires more enjoyable To melt snow and ice Your score is 0% Restart quiz Go to the Quizzes Page
