  Description:   In prior grades students learned to identify several different forms of energy. In grades 4-5 students build on their intuitive understanding of energy and learn how heat, light, sound, and electrical energy are generated and can be transferred from place to place. For example, they can observe that energy of motion can be transferred from one object to another. They can observe how heat energy is generated and moves from a warmer to a cooler place, and how sound can be produced by vibrations in the throat or guitar strings or other forms of vibration. They can also see that electrical energy can do many things, including producing light, heat, and sound, and can make things move. This introduction to the many forms of energy helps to prepare students for later studies of energy transformation and conservation.  
  Content Standard:   4-5 PS3C Heat energy can be generated a number of ways and can move (transfer) from one place to another. Heat energy is transferred from warmer things to colder things.  
Students are expected to:
  • Identify several ways to generate heat energy (e.g., lighting a match, rubbing hands together, or mixing different kinds of chemicals together).
  • Give examples of two different ways that heat energy can move from one place to another, and explain which direction the heat moves (e.g., when placing a pot on the stove, heat moves from the hot burner to the cooler pot).
