Kids Bowling Ball
How do I explain some science concepts to little kids?
I volunteered to help out at a science festival thing at an elementary school, but the topics are all physics-related, so I have no idea what they are:
1. standing waves (demo:slinky)
2. resonance (demo:tuning fork, Chinese spouting bowl)
3. energy conversion (demo:metal balls you strike on paper to burn a little hole, name?)
4. temperature (demo:polarized light crystal sheet)
Give me a little background (easily understood, I don't really want to know too many physics terms) on each, and how to explain it to little kids... Thanks! 
But I dont KNOW why...
Thanks, icez, more explanations please...
1-Most waves will move along - imagine, perhaps, an ocean. You'll see the peaks of the waves travelling towards the beach. Sometimes though, the wave will actually remain still - the peaks will still bob up and down but in the same place. There is a nice animation at: http://en.wikipedia.org/wiki/Standing_wave
2- Everything has a "natural frequency". If you put a oscillate (jiggle) something at its natural frequency, the harmony of the two will allow the jiggling to become much stronger. A tuning fork will hum at its own natural (resonant) frequency for example.
As you approach the natural frequency the waves will get bigger and bigger until they reach their maximum at resonance.
Incidentally
3-The kinetic energy of the balls are instantly converted into heat energy. This is a demonstration of the fact that energy is not created or destroyed but rather converted into other forms. The BANG you hear is also some of the kinetic (moving) energy transformed into sound energy.
4-Temperpature is tricky. In laymans terms its the amount that all the particles in a substance are jiggling about. The higher the temp, the more the jiggling.
