BIG IDEAS

Natural sources of energy can be classified as renewable and nonrenewable energy resources.


UNDERSTANDING THE STANDARD

  • The sun is the source of almost all energy on Earth. The sun is the direct source of light and thermal energy.
  • Sunlight, water, and wind are sources of energy. The force of flowing water and moving air (wind) can also be used to generate electricity.
  • Wood comes from trees. It has many important uses, including its use as a fuel.
  • Some energy sources are renewable. That means that they can be replaced. Some energy sources are nonrenewable. That means that once they are used up, they are gone and cannot be replaced. Coal, oil, and natural gas are nonrenewable resources.
  • Fossil fuels, such as coal, oil, and natural gas, are formed from decayed plants and animals. The formation of fossil fuels takes millions of years.

ESSENTIALS

Essential Questions:

·  What are sources of renewable energy?

·  What are sources of nonrenewable energy?

·  What are sources of energy use for?

In order to meet this standard, it is expected that students will

  • explain that the sun is the major source of energy for Earth.
  • identify sources of energy and their uses.
  • describe how solar energy, wind, and moving water can be used to produce electricity.
  • describe how fossil fuels are used as an energy source.
  • compare and contrast renewable and nonrenewable energy sources.
  • analyze the advantages and disadvantages of using different naturally occurring energy sources.
  • design a basic investigation to determine the effects of sunlight on warming various objects and materials, including water.
