You can create your own snowflakes on-line at Make-A-Flake. I found this at Not Martha, one of the non-educator weblogs that I read. This might be a good tool to use when discussing symmetry in the classroom. Here is one of the snowflakes that I created:

“Control your very own UFO as it glides, hovers and flies! The Vectron UltraLite is an infrared, remote control flying disc that’s ready to fly right out of the box. Just set it on the docking base, charge it for approximately 10 minutes, then stand back and watch it lift off, hover and fly around like an alien spacecraft. The special proportional controls mean the harder you press the trigger, the higher it flies. Just ease off the trigger to make Vectron descend. Designed for indoor use, this unique design is completely safe – the propeller stops instantly and automatically upon contact with any object.”
Ms. Frizzle has written a really clever song about hydrogen to be sung to the tune of a popular Christmas carol. Here is an excerpt of the song:
Hydrogen (Sing to the tune of “Jingle Bells”)
Atomic number one
Oh what a bang it is to be the fuel inside the sun
atomic number one
Oh what a bang it is to be the fuel inside the sun

The image to the left is an x-ray image of a columbine. The “secret garden” is a collection of x-ray images of flowers have been taken by Albert Richards, a University of Michigan Professor Emeritus, over the past forty years. Check out the rest of his images at his on-line photo gallery.
Dr. Richards describes his collection as follows:
“Flowers speak for us in many ways. On happy occasions we send flowers to express our joy and on sad occasions to express our sorrow. Almost everyone is fond of flowers, but they may never see the secret beauty that lies hidden within the blossoms. When we close our eyes, we cannot see the beautiful flowers around us. Even with our eyes wide open, we see only that portion of the flower that is nearest us, the same portion that would be recorded by a camera.”
REMINDER!!! Don’t forget to set your clocks back before you go to bed tonight. And if you want to learn why we “spring ahead, fall back”. There are a few sights on the web that discuss the history of Daylight Saving Time. Learn NC (the North Carolina teachers’ network) has links to a number of sites relevant to Daylight Saving Time, including a link to a WebExhibit site that describes the history of this custom.
Here is another neat “web pick” from the Discover Magazine web site…
The Alliance for Innovative Manufacturing at Stanford University brings us “How Everyday Things Are Made.” This site describes (through movies and diagrams) how everything is made…from crayons, to jellybeans, airplanes, glass bottles, denim fabric, etc. The site was designed to introduce people to the “world of manufacturing.”
You can also follow links to:
on-line factory tours
information about manufacturing processes (as pdf documents)
Note: Viewing this site over a DSL line or Cable modem will provide optimal results. You will also need Macromedia FlashPlayer plugin (6.029 or greater) to watch the movies.
Scientists at the University of of Loughborough in Leicestershire, England have found out why you often find broken cookies in packages of store-bought cookies…
Here is a fun link from a research group in Germany. This site allows you get a feel for how this group uses computers to visualize and breakdown biological motion…which in this particular case is a human being walking.
