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. 2 / 20 What is conduction? The way heat moves through liquids and gases. The movement of heat from one solid to another from direct contact. Any material that allows heat to move through it easily. The movement of energy by waves. 3 / 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. 4 / 20 What are the three major types of heat transfer? Convection, Conduction, Nuclear Conduction, Radiation, Chain Reaction Convection, Conduction, Radiation Convection, Radiation, Atomic 5 / 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. The fire gets bigger when warm air rises. Warm air rises, carrying heat with it. 6 / 20 How does a spark help start a fire? It provides the air It provides the initial heat It provides the oxygen It provides the fuel 7 / 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 sun directly touching the ground to transfer heat. The heat waves from the sun heating up the ground 8 / 20 What three things does fire need to burn? Fuel, oxygen and heat Paper, sticks and lighter Fuel, water and oxygen Fuel, water and paper 9 / 20 What is a natural type of radiation? 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. The heat waves from the sun heating up the ground 10 / 20 What is an conductor? The energy of moving particles. 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 tool that is used to measure how hot or cold something is. 11 / 20 What is radiation? 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. 12 / 20 What does fire give off that makes us feel warm? Wind energy Sound energy Heat energy Light energy 13 / 20 How does heat travel from a mug of hot tea to your hands? By convection By combustion By conduction By radiation 14 / 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 15 / 20 What are examples of materials that transfer heat well? Styrofoam Steel Gold Iron 16 / 20 What is the narrator's main point in this story? To teach how to build a campfire To show the importance of spending time with dad To explain how fire and heat work together 17 / 20 Besides conduction, how else can you feel the fire's warmth even if you're not touching it? By radiation By smelling the smoke By seeing the flames 18 / 20 What is the difference between conduction and radiation? Conduction requires touching something hot, radiation doesn't. Both answers are correct. Conduction is faster, radiation is slower. 19 / 20 What is convection? 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. 20 / 20 What is an insulator? 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. Any material that does not allow heat (or electricity) to pass through it easily.
