A dam backs up water so that the water level gets higher and higher.
As a result the water stores more and more energy that can be used as it
flows through a turbine which turns a generator inside the dam powerhouse.
As the generator spins from the moving water it creates electricity that can be
sent through long distance power lines to homes. Once the electricity gets to the
home it can be converted or transformed into many other forms of energy.
3. As backed up water flows through the intake and into the penstock an energy transformation occurs.
Which best describes this transformation?
a. electrical to heat
c. kinetic to electrical
b. gravitational potential to kinetic
d. potential kinetic to electrical
4. What best describes energy as it was described in this learning module?
a. energy is always in the same form
b. energy can be completely destroyed
c. energy can only be changed from one form to another
d. energy can be created
Standard 4 COMPONENT 11 Essential Questions Key
1.) Explain two different chains of energy transformations. Each must have at least 3 steps.
Sunlight getting changed into plant material (chemical potential energy) then being eaten by a rabbit and
turned into muscle tissue (chemical potential energy), the rabbit being eaten by a fox and converted into
body temperature of the fox (heat) and allowing the fox to run (kinetic energy).
Water stored behind a dam has potential energy. The water starts to fall down a flume, which is kinetic, and
turns a turbine. The turning turbine is also kinetic. The turbine generates electrical energy which is then
transmitted to home via a wire. This allows a light to be turned on and this would be light energy.
