Forms of Energy Worksheets:
What is Energy? -
Energy is most simply understood as the ability to do work. All living things
use it to maintain life, grow, change, and move. We use it to
prepare meals, to travel in a car, and to brush our teeth.
Biomass is plant or animal matter that can be converted to energy. The
reason that biomass can be converted to energy is because it contains
stored energy that originated from the sun.
QUESTIONS: Biomass -
Why is biomass considered a renewable and what does that mean? Why isn't there an unlimited supply of biomass?
Geothermal energy is considered a renewable source because
the Earth is always being warmed by its core. It is also a very clean in that using it has a negligible impact on the environment.
QUESTIONS: Geothermal -
Which of the following is NOT a way to harness geothermal? This is just started to get more traction and use.
The technology behind solar panels is called Solar Photovoltaic (PV). Solar
PV generates energy by converting solar radiation (i.e., sunlight) into
direct current electricity using semiconductors.
QUESTIONS: Solar -
Why is solar power considered an efficient way to generate electricity? In the last 20 years this has become much more commonly used.
Hydro means water. Hydropower is power that is generated using energy
from moving water. Hydropower is considered a renewable source because the water is not used up as it is used like is the case with
coal or oil.
Wave and Tidal Forms -
Wave energy is harnessed from the movement of the waves on
the ocean. Waves are created when wind moves across the ocean's
surface. A great deal of energy is stored in waves.
Wind power is generated by harnessing the energy of the wind. Wind
power is considered a renewable source because the wind
cannot be used up, like coal and oil.
QUESTIONS: Wind -
Wind turbines blades are typically between how long? The turbine is an amazing invention.
Kinetic Forms -
Kinetic energy is the opposite of potential. Potential is the direct
result of an object's position or state. For example, an object on a high
shelf has potential energy that becomes kinetic when it falls off the
Potential Energy -
It has an inverse relationship with kinetic energy. The more
kinetic energy an object gains, the less potential it has. A classic
example to explain the relationship between them is the roller coaster example.
Chemical Energy -
Chemical energy is stored in the bonds of atoms and
molecules. It is released during a chemical reaction,
when atoms are rearranged as a result of chemical change.
