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 fire gets bigger when warm air rises. The logs burn faster because of hot air. Convection creates sparks for the fire. Warm air rises, carrying heat with it. 2 / 20 What is radiation? 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. 3 / 20 Besides conduction, how else can you feel the fire's warmth even if you're not touching it? By smelling the smoke By seeing the flames By radiation 4 / 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 energy by waves. The movement of heat from one solid to another from direct contact. 5 / 20 What is a natural type of radiation? 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. 6 / 20 What is a natural type of conduction? 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 7 / 20 What is the narrator's main point in this story? To teach how to build a campfire To show the importance of spending time with dad To explain how fire and heat work together 8 / 20 What does fire give off that makes us feel warm? Heat energy Wind energy Sound energy Light energy 9 / 20 What are the three major types of heat transfer? Convection, Radiation, Atomic Convection, Conduction, Nuclear Convection, Conduction, Radiation Conduction, Radiation, Chain Reaction 10 / 20 How is the sun similar to a fire in terms of heat? They both burn fuel. They both give off heat through radiation They both need oxygen to burn. 11 / 20 Why is heat important for life on Earth? To help animals stay warm and plants grow To melt snow and ice To make campfires more enjoyable 12 / 20 How does heat travel from a mug of hot tea to your hands? By convection By conduction By combustion By radiation 13 / 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 14 / 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 heat waves from the sun heating up the ground. The ground heating the air that is touching the ground. 15 / 20 What is an insulator? Any material that does not allow heat (or electricity) to pass through it easily. The energy of moving particles. 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. 16 / 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 17 / 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. 18 / 20 What are examples of materials that transfer heat well? Steel Iron Styrofoam Gold 19 / 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. 20 / 20 What is convection? 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. The way heat moves through liquids and gases. Your score is 0% Restart quiz Go to the Quizzes Page
