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. The fire gets bigger when warm air rises. Convection creates sparks for the fire. Warm air rises, carrying heat with it. 2 / 20 What is conduction? Any material that allows heat to move through it easily. The movement of energy by waves. The way heat moves through liquids and gases. The movement of heat from one solid to another from direct contact. 3 / 20 What is a natural type of conduction? 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 4 / 20 What does fire give off that makes us feel warm? Heat energy Light energy Sound energy Wind energy 5 / 20 What three things does fire need to burn? Fuel, water and oxygen Fuel, oxygen and heat Paper, sticks and lighter Fuel, water and paper 6 / 20 What is an conductor? 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. The energy of moving particles. Any material that does not allow heat (or sound) to pass through it easily. 7 / 20 What is a natural type of convection? 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. 8 / 20 What is a natural type of radiation? The sun directly touching the ground to transfer heat. The heat waves from the sun heating up the ground The ground heating the air that is touching the ground. The warm air heated by the ground rising 9 / 20 How does a spark help start a fire? It provides the initial heat It provides the fuel It provides the oxygen It provides the air 10 / 20 What is the difference between conduction and radiation? Conduction is faster, radiation is slower. Conduction requires touching something hot, radiation doesn't. Both answers are correct. 11 / 20 What is radiation? The movement of heat from one solid to another. Any material that allows heat to move through it easily. The movement of energy by waves. The way heat moves through liquids and gases. 12 / 20 What is an insulator? 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. The tool that is used to measure how hot or cold something is. 13 / 20 How is the sun similar to a fire in terms of heat? They both need oxygen to burn. They both give off heat through radiation They both burn fuel. 14 / 20 How does heat travel from a mug of hot tea to your hands? By convection By combustion By conduction By radiation 15 / 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 16 / 20 What are the three major types of heat transfer? Convection, Conduction, Radiation Convection, Radiation, Atomic Convection, Conduction, Nuclear Conduction, Radiation, Chain Reaction 17 / 20 What is the narrator's main point in this story? To teach how to build a campfire To explain how fire and heat work together To show the importance of spending time with dad 18 / 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. 19 / 20 What are examples of materials that transfer heat well? Styrofoam Iron Steel Gold 20 / 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 Your score is 0% Restart quiz Go to the Quizzes Page
