Acid - a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper.
Atomic Energy - Produced when you split atoms, the smallest particle known to man. A tremendous amount of energy is released when this happens.
Atoms - An atom is the basic unit of all matter. Everything is made up of tiny atoms.
Chemical Energy - is the energy stored in food, gasoline or chemical combinations.
Chemical Reaction - is aprocess by which one or more substances may be transformed into one or more new substances.
Conductor - an object that readily transfers heat, electricity or sound.
Conservation - the careful use of a natural resource so we don't use it up.

Circuit - a path for electric currents.

  • Open Circuit - a disconnected circuit through which no current can flow.
  • Closed Circuit - a connected circuit, providing a continuous path through which a current can flow.
Electrical Energy - Energy produced by electrons moving through a substance is known as electrical energy. We mostly see electric energy in batteries and from the outlets in our homes.
Energy - the ability to do work.

Energy Path - is the path that energy follows as it transfers from one form to another.

Fossil Fuels - any combustible organic material, as oil, coal, or natural gas, that comes from the remains of dead plants and animals.
Hydroelectric Energy - electricity generated from falling water.
Kinetic Energy - is energy in motion.
Mechanical Energy - is moving energy. It is the form we most often see around us. All moving objects produce mechanical energy. The movements within machines are also mechanical energy.
Medium - a substance through which something is carried. For example - air is the common medium of sound.
Molecules - are made up of two or more atoms. For example a water molecule is made up of two hydrogen atoms and one oxygen atom also known as H2O.
Movement - to pass from one place or position to another.
Natural Resources - natural materials used in producing power and material goods; consisting of land, forests, mineral deposits, water, etc.
Potential Energy - is stored energy.
Radiant Energy - is a combination of heat and light energy. Light energy, like sound energy, travels out in all directions in waves.
SCREAM - stands for the 6 forms of energy we study in Needham: sound, chemical, radiant, electrical, atomic and mechanical.
Solar Energy - is energy produced by the sun, including light, radio waves, and X rays.
Sound Energy - is produced when an object is made to vibrate. Sound energy travels out as waves in all directions. Sound needs a medium to travel through, such as air, water, wood, and even metal
Vibrations - movement to and fro or up and down.
