SOME THINGS TO TRY FOR YOURSELF
1. Hand Rubbing
A very easy way for you to see how energy can change from one type
to another is to rub your hands together really fast, and keep going
for as long as you can.
How do your hands feel? Warm, cold, or hot.
Do you know what type of energy that movement is? Mechanical, chemical,
or electrical.
2. Balloon
If you blow up a balloon you use energy to do it, and that energy
gets transferred to the balloon as potential energy. That means
the balloon is storing the energy. The balloon has the potential
to do something...
a) If you let go of the balloon before
you tie it, what happens? It flies all around the room. You released
the potential energy to create the mechanical energy of the moving
balloon.
b) If you let the air out but hold
on to the balloon so that it makes a squeaking noise you can turn
the potential energy into sound energy.
c) If you tie the balloon to stop
it from going down, can you think of a way to release the energy
really quickly to make sound energy?
