  • The chemical energy in food helps our body to _____.
    Function
  • What 3 sources can primary materials come from?
    Animals, minerals, and vegetables.
  • Uranium and plutonium have _____ energy.
    Nuclear
  • What is light energy?
    Energy that travels with light (for example: photosynthesis).
  • What is nuclear energy used for?
    To produce electrical energy in nuclear power plants.
  • What are non-renewable materials?
    Non-renewable materials will eventually run out because they are used faster than they are produced. Examples: Fossil fuels, uranium, and plutonium.
  • All changes in matter involve energy in one way or another. True or False?
    True
  • Pure substances contain only ____ type of material.
    One
  • Give me examples of pure substances.
    Oxygen, gold, salt, and sugar.
  • Examples of mineral sources include…
    Gold, silver, iron, natural gas, and petroleum.
  • What is a substance and give me an example of one.
    Substances are where matter exists. For example: wood, plastics, air, carbon, and diamonds.
  • What is the difference between pure substances and mixtures?
    A pure substance contains only one type of material. A mixture contains two or more types of material.
  • Thermal energy passes from warmer bodies to cooler ones. True or False?
    True
  • Lightning is an example of _______ energy.
    Electrical
  • What is potential energy?
    The energy an object has due to its position.
  • Examples of vegetable sources include…
    Wood, cotton, and rubber.
  • What are renewable materials?
    Renewable materials do not run out because they are produced faster than they are used. Examples: the Sun, wind, flowing water.
  • Wood, plastic, air, carbon, and diamond are all examples of…
