  Grade Level:   4-5  
  EALR 4:   Physical Science  
  Big Idea:   Energy: Transfer, Transformation, and Conservation (PS3)  
  Core Content:   Heat, Light, Sound, and Electricity                   
  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 PS3B Energy can be transferred from one place to another.  
Students are expected to:
  • Draw and label diagrams showing several ways that energy can be transferred from one place to another (e.g., sound energy passing through air, electrical energy through a wire, heat energy conducted through a frying pan, light energy through space).
