Endothermic and Exothermic Heat -Meena

Endothermic heat is when heat is absorbed by a second part such as when you hug someone their body heat is being released and taken in by the other person.  Exothermic heat is when heat is let out.  The sun, for example, is constantly releasing rays of heat therefore it is exothermic.  In my 8th grade science class I did a simulation where there was a fire and water on top.  In this simulation the fire was releasing heat (Exo) and the water was using that heat to boil (Endo).  My video shows endo and exo thermic heat because I sat by a fire that released sparks of flames that warmed me because I was an endothermic example of the fires exothermic exposure. Therefore my Video is endo and exo thermic because it shows evidence of a consumer as well as a producer.

Heat Increase Rule - Hitting a Tennis Ball -Karlee

Thermal energy is thought of the most wasteful type of energy out there, it is the ultimate result of every energy will result as heat. You can't do much with heat right now, but as technology advances, solar power would be more common and advanced to create more energy. As potential energy transforms into kinetic energy, which then transforms into heat energy, heat energy will always build up. In other words, the result of energy. It is what is created after the "work" or motion has been completed. In the High Five Video, Karlee and Ai Vy were hitting the tennis ball back and forth proves that because as the ball moves, there were transfers of heat on the court and in the air. This happened until potential and kinetic energy will not exist in the system and its all become into thermal energy.This means thermal energy will always increase in a system, also resulting in the tennis ball stopped.
