Homework Read 30 minutes Iris: Read up to chapter 6 and complete questions. Due: Friday PJ Day Monday is going to be pajama day. Come to school in your comfiest pajamas. Science Today we learned about the different forms of energy. Here are some of the vocabulary words we talked about today: chemical energy: The energy stored on the chemical bonds of molecules that it released during a chemical reaction. Chemical energy holds molecules together and keeps them from moving apart. For example, a car engine uses chemical energy stored in gasoline, and moving people use chemical energy from food. electrical energy: Electrical energy exists when charged particles attract or repel each other. Television sets, computers and refrigerators use electrical energy. energy: The ability to do work. kinetic energy: The energy of motion. For example, a spinning top, a falling object and a rolling ball all have kinetic energy. The motion, if resisted by a force, does work. Wind and water both have kinetic energy. light energy: Visible light energy, such as from a light bulb or fireflies or stars, is just one form of electromagnetic energy. Others forms include infrared and ultraviolet light. mechanical energy: Mechanical energy is energy that can be used to do work. It is the sum of an object's kinetic and potential energy. potential energy: Potential energy is the energy stored by an object as a result of its position. A roller coaster at the top of a hill has potential energy sound energy: Audible energy that is released when you talk, play musical instruments or slam a door.
