To teach how to build a campfire To explain how fire and heat work together To show the importance of spending time with dad 2 / 20 What is a natural type of radiation? 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. The heat waves from the sun heating up the ground 3 / 20 What is conduction? The movement of energy by waves. 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. 4 / 20 What does fire give off that makes us feel warm? Heat energy Sound energy Light energy Wind energy 5 / 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 6 / 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. 7 / 20 What are the three major types of heat transfer? Convection, Conduction, Radiation Convection, Conduction, Nuclear Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction 8 / 20 What three things does fire need to burn? Paper, sticks and lighter Fuel, water and oxygen Fuel, water and paper Fuel, oxygen and heat 9 / 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. 10 / 20 How does convection help us feel warm around the campfire? The fire gets bigger when warm air rises. Convection creates sparks for the fire. Warm air rises, carrying heat with it. The logs burn faster because of hot air. 11 / 20 What is the difference between conduction and radiation? Both answers are correct. Conduction requires touching something hot, radiation doesn't. Conduction is faster, radiation is slower. 12 / 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. 13 / 20 What is an insulator? 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. The energy of moving particles. 14 / 20 What is a natural type of conduction? The warm air heated by the ground rising 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 15 / 20 How does a spark help start a fire? It provides the fuel It provides the initial heat It provides the oxygen It provides the air 16 / 20 How does heat travel from a mug of hot tea to your hands? By combustion By convection By conduction By radiation 17 / 20 What is radiation? 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. 18 / 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 19 / 20 What are examples of materials that transfer heat well? Styrofoam Steel Iron Gold 20 / 20 Why is heat important for life on Earth? To make campfires more enjoyable To melt snow and ice To help animals stay warm and plants grow Your score is 0% Restart quiz Go to the Quizzes Page
