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 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 3 / 20 What is an insulator? Any material that allows heat (or electricity) to move through it easily. Any material that does not allow heat (or electricity) to pass through it easily. The tool that is used to measure how hot or cold something is. The energy of moving particles. 4 / 20 How does heat travel from a mug of hot tea to your hands? By combustion By radiation By conduction By convection 5 / 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 6 / 20 What does fire give off that makes us feel warm? Light energy Sound energy Heat energy Wind energy 7 / 20 How does convection help us feel warm around the campfire? The logs burn faster because of hot air. Warm air rises, carrying heat with it. The fire gets bigger when warm air rises. Convection creates sparks for the fire. 8 / 20 What is a natural type of convection? 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. The sun directly touching the ground to transfer heat. 9 / 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. 10 / 20 What are examples of materials that transfer heat well? Steel Styrofoam Iron Gold 11 / 20 How does a spark help start a fire? It provides the oxygen It provides the initial heat It provides the fuel It provides the air 12 / 20 What is conduction? 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. The way heat moves through liquids and gases. 13 / 20 What is convection? 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. The movement of energy by waves. 14 / 20 What is radiation? 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. 15 / 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. 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 an conductor? 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. Any material that does not allow heat (or sound) to pass through it easily. 18 / 20 What three things does fire need to burn? Fuel, water and paper Fuel, water and oxygen Paper, sticks and lighter Fuel, oxygen and heat 19 / 20 Why is heat important for life on Earth? To make campfires more enjoyable To help animals stay warm and plants grow To melt snow and ice 20 / 20 What is a natural type of conduction? 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 The sun directly touching the ground to transfer heat. Your score is 0% Restart quiz Go to the Quizzes Page
