Energy is what gives us the ability to do stuff, to make things
move, to make things happen!

ENERGY COMES IN SEVERAL DIFFERENT TYPES. THERES TWO BASIC WAYS
THAT YOU CAN CLASSIFY THEM.

-
LIGHT ENERGY IS THE MOVEMENT OF PHOTONS, or PARTICLES OF
LIGHT.
LIGHT ENERGY MOVES IN A WAVE-LIKE MOTION AS IN TRAVELS. CHANGING
THE WAVES LENGTH CHANGES THE TYPE OF LIGHT.

TRANSMITTED THROUGH SPACE IN THE FORM OF WAVES
DOES NOT NEED A MEDIUM TO TRAVEL THROUGH
LIGHT ENERGY IS A FORM OF ELECTROMAGNETIC ENERGY

When you think of heat and thermal energy, you might think of
something like these
*
-
or this
*
-
Or maybe even this!
*
-
Thermal energy is the movement of molecules in an object. Its
actually easier to understand with water than fire!

1. In which beaker of water did the food coloring spread through
the water the fastest?2. Water is made of millions of tiny water
molecules. Which do you think moves faster, warm molecules or cold
molecules? Why?3. Steam is made by heating water until it boils and
becomes a gas. Which do you think move faster, molecules of steam
or molecules of hot water? Why?4. Based on what you have learned
about temperature and molecular movement, should you add ice or
heat to a sprained ankle to prevent it from swelling? Explain your
answer.

**WARNING**Do not try any of the following at home! This is a
very dangerous experiment that is being performed in a controlled
setting that has been specifically designed to handle extreme heat
and reactions that may occur. Safety precautions include the use of
safety goggles, lab station with heat resistant counters, running
water, a trained professional adult, emergency water shower,
emergency eye wash, fire blanket, and first aid kit. Performing
this experiment in your own home could result in injury to either
yourself or others and can cause damage to counters, pluming, and
any other surface that the flame could come in contact with.
Similar experiments are also discouraged for the well being of the
child and any other persons involved. Again, DO NOT PERFORM THIS AT
HOME.

1. What type of energy is in the solution Ms. Norris pours on
the objects?2. When Ms. Norris sets the different objects on fire,
why (for the most part) do they not burn?3. Why did the water
bottle react differently than the other objects when it was set on
fire?4. List in order the energy transfers that took place when
SpongeBob was set on fire.5. How does this experiment show how
chemical energy is a form of potential energy?
