Try locating hot,
high, or fast in the following locations:

*Note: This way of identifying energy sounds
a bit vague but in fact is based on good science.
"Hot" - Something that
is hot has heat energy. The hotter and larger
it is, the more heat energy it has, and the faster the molecules
are going.
"High" - Something that
is high has the potential to fall because gravity
pulls on it. This is only one kind of potential energy, energy
that is stored and ready to go.
"Fast" - Something that
is fast is moving at a high speed and has been
given a force to move. The faster and bigger the fast object
is, the more motion energy it has.
2. Can you find examples of
objects gaining
or losing energy?
Now that you can find things with
energy, look for clues that objects are changing
energy.
If it is heating up, speeding up
or being lifted up, the object is gaining energy.
If it is cooling down, slowing
down or going down, then it is losing
energy.
Talk together as a class or in
small groups, and write examples you can recall from your own
neighborhood in the Energy Change
Chart.
3. Learning new names:
These types of energies we have
talked about have technical names, and they are:
When somethings is hot,
we will say that has heat
energy.
When something is high,
we will say that is has gravitational
potential energy.
When somethings is moving,
we will say that it has kinetic
energy.
You can learn these more easily
if you back to the chart and write the technical names next to
your examples. Energy Change
