To help animals stay warm and plants grow To melt snow and ice To make campfires more enjoyable 2 / 20 What is a natural type of radiation? 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 The sun directly touching the ground to transfer heat. 3 / 20 What are examples of materials that transfer heat well? Styrofoam Gold Iron Steel 4 / 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 5 / 20 How is the sun similar to a fire in terms of heat? They both give off heat through radiation They both need oxygen to burn. They both burn fuel. 6 / 20 What is convection? The movement of heat from one solid to another. The way heat moves through liquids and gases. The movement of energy by waves. Any material that allows heat to move through it easily. 7 / 20 What is an insulator? 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. Any material that allows heat (or electricity) to move through it easily. The energy of moving particles. 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 conduction? The way heat moves through liquids and gases. The movement of energy by waves. The movement of heat from one solid to another from direct contact. Any material that allows heat to move through it easily. 10 / 20 What is the narrator's main point in this story? To show the importance of spending time with dad To explain how fire and heat work together To teach how to build a campfire 11 / 20 What does fire give off that makes us feel warm? Wind energy Sound energy Heat energy Light energy 12 / 20 What are the three major types of heat transfer? Convection, Conduction, Radiation Convection, Conduction, Nuclear Conduction, Radiation, Chain Reaction Convection, Radiation, Atomic 13 / 20 How does a spark help start a fire? It provides the oxygen It provides the air It provides the fuel It provides the initial heat 14 / 20 How does convection help us feel warm around the campfire? Convection creates sparks for the fire. The logs burn faster because of hot air. Warm air rises, carrying heat with it. The fire gets bigger when warm air rises. 15 / 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. 16 / 20 What is a natural type of conduction? The warm air heated by the ground rising 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. 17 / 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. 18 / 20 How does heat travel from a mug of hot tea to your hands? By combustion By conduction By convection By radiation 19 / 20 What is a natural type of convection? 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. 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.
