There is science behind every sound we hear. Sound is made from vibrations in the air. Different materials making different vibrations make different sounds based on the amplification and speed of the sound wave. Here are some of our favorite materials and experiments with sound - Screaming Cup (the stick and slide method), a Thunder Tube, Space Phone, Talking Strips, Singing Rod and Sound Hose. Another favorite is Boomwhackers.
It was easy to see that this Steve Spangler session at the NAEYC 2006 Conference was going to be a little different. The stage was filled with the usual Spangler stuff… a vacuum cleaner, eggs, a saw, bowling balls, toilet paper rolls, giant bags, an aquarium of water, a violin bow, plenty of Alka-Seltzer, potatoes, Diet Coke and, of course, Mentos. Even before Bobbi finished the introduction, there were Mentos Geysers erupting and people running!
My thanks to everyone who attended my session at the NAEYC 2006 conference in Atlanta, Georgia. You’ll find links to the experiments and activities that I shared during the session as well as a few favorites that didn’t make it into the list of 20 Cool Science Activities Under $20.
