"That's why you would like diigo. You can search your bookmarks. You can annotate them also and search these.So, I annotate them with how I used them in class and then it makes it easy to find. I'm sure there are other services. "

"I just create folders to organize the type of bookmarked source...Student Resources, Teacher Resources, Sci Videos, etc.  Even then, I need to remember to scour a folder when I'm scratching my head over a topic."

"Ohh, thanks for reminding me. ACS's Middle School Chemistry website got lost in my abundance of bookmarks. I really like the activities they have associated with chemical change. I'm using right now with my 7th graders"

'Captured lightning' Lichtenberg Figure

Full Text:

Pictured at left is a charged 4 inch x 12 inch x ½ inch specimen of acrylic plastic being discharged to form a "captured lightning" Lichtenberg figure. A neutral density filter was used to prevent the camera from being overexposed by the brilliant flash. A particle accelerator was used to charge up the interior of the specimen to over 1.7 million volts. By poking the edge with a grounded point, the trapped charge was suddenly released. Although the electrical discharge lasts for less than 250 billionths of a second, the miniature lightning-like discharges leave behind permanent branching chains of tubes and fractures inside the acrylic, effectively forming a "fossil" of the discharge. The fractal pattern is similar to many other branching forms in nature, such as animal circulatory systems, branching tree limbs, and rivers and their tributaries.
