Glass beads, crystal beads, and lampwork beads
Glass Beads are one of the most versatile types. Glass is one of the most often used material in bead making, it seems to have first been used in Eygpt and Rome, but also in India. Most glass beads are molded, but some blown glass beads are still made in Venice - these are very expensive.
Crystal Beads are made from glass with lead in it. A clean finish and crisp facets make these beads sparkle. They come in many shapes: round, bicone, teardrop, rondelle, etc. They are most often from Austria. Swarovski crystal beads are the best quality crystal beads, due to the lead content in the glass. They are measured in millimeters. The cheap Chinese crystal beads are also popular in the market, as they are cheaper than Swarovski crystal beads, but they are as shinning and lighting as the Swarovski crystal beads.
Lampwork Beads are artistic handmade beads. Hot glass is spun onto a copper wire (mandrel) over a flame (lamp) making each one unique. The bead can be further worked by adding other pieces of glass from rods called stringers, pieces of gold or silver leaf and millefiore. They can be very heavy and expensive. They are therefore usually used as a focal point in a beaded jewelry piece.
Glass beads, crystal beads, lampwork beads are all made by glass, there are also many other materials used to make beads which are also the common used to create beaded jewelry, such as the Tibetan silver used to form the Tibetan silver beads, which are great for Tibetan jewelry making, resin are used to create resin beads or resin cabochons…

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.
