To teach how to build a campfire To show the importance of spending time with dad To explain how fire and heat work together 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 is a natural type of conduction? The heat waves from the sun heating up the ground 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. 4 / 20 How does heat travel from a mug of hot tea to your hands? By convection By radiation By combustion By conduction 5 / 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. 6 / 20 What is an insulator? The energy of moving particles. 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. Any material that allows heat (or electricity) to move through it easily. 7 / 20 What are examples of materials that transfer heat well? Styrofoam Steel Iron Gold 8 / 20 What is convection? 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. The way heat moves through liquids and gases. 9 / 20 What three things does fire need to burn? Fuel, water and oxygen Fuel, oxygen and heat Paper, sticks and lighter Fuel, water and paper 10 / 20 How does convection help us feel warm around the campfire? Convection creates sparks for the fire. The fire gets bigger when warm air rises. The logs burn faster because of hot air. Warm air rises, carrying heat with it. 11 / 20 What are the three major types of heat transfer? Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction Convection, Conduction, Radiation Convection, Conduction, Nuclear 12 / 20 What is radiation? The movement of heat from one solid to another. The movement of energy by waves. The way heat moves through liquids and gases. Any material that allows heat to move through it easily. 13 / 20 What is an conductor? 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. The energy of moving particles. The tool that is used to measure how hot or cold something is. 14 / 20 How does a spark help start a fire? It provides the initial heat It provides the fuel It provides the oxygen It provides the air 15 / 20 Why is heat important for life on Earth? To help animals stay warm and plants grow To make campfires more enjoyable To melt snow and ice 16 / 20 What does fire give off that makes us feel warm? Wind energy Light energy Heat energy Sound energy 17 / 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. 18 / 20 What is a natural type of convection? 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. 19 / 20 What is conduction? The movement of heat from one solid to another from direct contact. The way heat moves through liquids and gases. The movement of energy by waves. Any material that allows heat to move through it easily. 20 / 20 Besides conduction, how else can you feel the fire's warmth even if you're not touching it? By radiation By seeing the flames By smelling the smoke Your score is 0% Restart quiz Go to the Quizzes Page
