The student is expected to differentiate among forms of energy, including mechanical, sound, electrical, light, and heat/thermal.
The student knows that energy exists in many forms and can be observed in cycles, patterns, and systems.
Energy Tutorial: National Fuel Cell Research Center (website) - Detailed descriptions of different energy sources employed for electricity generation, transportation, heating, etc.
Introduction to Energy: The NEED Project (PDF) - Explains different energy sources and the usage levels for various energy sources in the United States.
Making Objects Move: Science NetLinks (website) - Students study the motion of objects to create a structure that can be used to move an object from a place to another. They will manipulate the motion objects and explore the forces required to control the movement.

Spool Racer: PBS Kids (PDF) - Students make and test a spool racer to investigate potential and kinetic (mechanical) energy.
Elaboration Lessons and Extensions
Be Inventive! Museum of Science (website) - Students are challenged to invent simple machines that use mechanical energy to serve a specific purpose.
Move It! With Simple Machines: Science NetLinks (website) - Students explore mechanical energy by working with the six simple machines (lever, wedge, pulley, wheel and axle, inclined plane, and screw).
Have students work in groups to invent a machine that would solve a simple everyday problem (such as opening a door). Have them draw or describe their machines.
