Fuel, oxygen and heat Fuel, water and oxygen Paper, sticks and lighter Fuel, water and paper 2 / 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. 3 / 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. 4 / 20 What are the three major types of heat transfer? Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction Convection, Conduction, Radiation Convection, Conduction, Nuclear 5 / 20 What is convection? The way heat moves through liquids and gases. 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. 6 / 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 sun directly touching the ground to transfer heat. The warm air heated by the ground rising. 7 / 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. 8 / 20 What does fire give off that makes us feel warm? Light energy Heat energy Sound energy Wind energy 9 / 20 How does heat travel from a mug of hot tea to your hands? By radiation By convection By combustion By conduction 10 / 20 What is a natural type of conduction? The heat waves from the sun heating up the ground The sun directly touching the ground to transfer heat. The ground heating the air that is touching the ground. The warm air heated by the ground rising 11 / 20 Why is heat important for life on Earth? To melt snow and ice To make campfires more enjoyable To help animals stay warm and plants grow 12 / 20 What is the difference between conduction and radiation? Conduction requires touching something hot, radiation doesn't. Conduction is faster, radiation is slower. Both answers are correct. 13 / 20 What is the narrator's main point in this story? To explain how fire and heat work together To show the importance of spending time with dad To teach how to build a campfire 14 / 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 15 / 20 How does a spark help start a fire? It provides the fuel It provides the air It provides the initial heat It provides the oxygen 16 / 20 What is conduction? The way heat moves through liquids and gases. 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 from direct contact. 17 / 20 What are examples of materials that transfer heat well? Gold Iron Steel Styrofoam 18 / 20 What is an insulator? The energy of moving particles. 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. 19 / 20 What is a natural type of radiation? The heat waves from the sun heating up the ground The sun directly touching the ground to transfer heat. The warm air heated by the ground rising The ground heating the air that is touching the ground. 20 / 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.
