Fuel, water and oxygen Fuel, oxygen and heat Paper, sticks and lighter Fuel, water and paper 2 / 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 warm air heated by the ground rising. The heat waves from the sun heating up the ground. 3 / 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 4 / 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. 5 / 20 How does convection help us feel warm around the campfire? The fire gets bigger when warm air rises. Warm air rises, carrying heat with it. The logs burn faster because of hot air. Convection creates sparks for the fire. 6 / 20 How does heat travel from a mug of hot tea to your hands? By convection By conduction By radiation By combustion 7 / 20 What is the narrator's main point in this story? To show the importance of spending time with dad To teach how to build a campfire To explain how fire and heat work together 8 / 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. 9 / 20 What is conduction? 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. The way heat moves through liquids and gases. 10 / 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 11 / 20 What is radiation? 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. 12 / 20 What is an insulator? The energy of moving particles. 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. 13 / 20 How does a spark help start a fire? It provides the fuel It provides the initial heat It provides the air It provides the oxygen 14 / 20 What is convection? 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. 15 / 20 What are the three major types of heat transfer? Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction Convection, Conduction, Radiation Convection, Conduction, Nuclear 16 / 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 warm air heated by the ground rising The ground heating the air that is touching the ground. 17 / 20 What does fire give off that makes us feel warm? Sound energy Light energy Heat energy Wind energy 18 / 20 What is an conductor? Any material that does not allow heat (or sound) to pass through it easily. The energy of moving particles. 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. 19 / 20 What are examples of materials that transfer heat well? Steel Gold Iron Styrofoam 20 / 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.
