(this animation has loud sounds) press the green flag 5 times and enjoy Jesus loves you :) I made this for a middle school thermal energy project...

subtitles: Did you know that there's something called thermal energy? There's just one big question: what is thermal energy? You see, all matter is made up of particles that are in constant motion, and the energy of that motion is known as kinetic energy. But, all particles don't have the same amount of kinetic energy, so when we're finding the temperature of a substance, we're finding the average kinetic energy of its particles. The thermal energy of a substance depends on its temperature AND the quantity of particles it contains, so a cup of water and a pool of water may have the same temperature, but the pool has more thermal energy because it has more water. Thermal energy "flows" from warmer areas to cooler areas, and heat is a way to measure this flow. Thermal energy is transferred in three main ways: conduction, convection, and radiation. Conduction transfers thermal energy through direct contact: if you put a metal pot over a hot stove, the metal pot gets warmed up. Heat is transferred from warmer, faster-moving particles to cooler, slower-moving particles. Some materials, such as metal, conduct heat better than others. Next up, we have convection. Convection transfers thermal energy through the movement of fluids. If we fill up a pot with water and put it over a hot stove, the hot stove warms up the water. As the warm water rises, it pushes cold water away, creating a convection current. Convection transfers heat through the movement of the particles in a liquid or gas. The movement of the heated material carries energy away from the heat source. Next up, we have radiation. Radiation transfers thermal energy through electromagnetic waves, like holding up a pot full of hot water up to a thermometer raises the thermometer's temperature, even though the pot isn't touching it. Radiation can carry thermal energy from object to object- even through empty space. When electromagnetic waves strike a material, the particles in the material absorb energy and move faster. Certain materials are better at absorbing thermal radiation than other surfaces. Dark surfaces are better at absorbing thermal energy than lighter surfaces, and rough surfaces are better at absorbing thermal energy than smoother surfaces, but all objects absorb and emit thermal radiation. Well, we've seen what thermal energy is, and we've seen what conduction, convection, and radiation are, so let's try to find examples of them in the real world. Picture roasting marshmallows by a campfire. Using a metal rod to hold the marshmallow is a bad idea because metal is a good conductor of thermal energy, so the metal rod would quickly become too hot to hold. Let's try using a wooden twig instead. A wooden twig would be a better material to hold the marshmallow with because wood is a poor conductor of thermal energy. Now we can enjoy our marshmallows! Let's go back to that campfire. There's smoke emitting from the campfire, right? Well, smoke is a gas, which contains liquid, making it a fluid. As the air around the campfire is heated and becomes less dense, it rises and moves upward, creating a convection current that transfers heat. You can see this natural convection as smoke rises from the fire. Let's go back to the campfire one more time... and forget about the marshmallows. Thermal energy radiates from the campfire, so the warmth you feel when sitting next to it is from the transfer of thermal energy by radiation, and the marshmallow held by the fire also gains thermal energy from radiation, which toasts the marshmallow... but... there's no marshmallow anymore. Anyways, I've taught you all I know about thermal energy, so congratulations on finishing the animation! YIPPEE!!1!!!1!11!!!!11!
