Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these examples of how energy is changed, write the correct answer in the blank. In photosynthesis, solar energy undergoes a when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is to land and water.

Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.

While energy can be transferred or transformed, the total amount of energy does not change ­– this is called energy conservation.
