insectgearmov

Teachable Moment: This is a great example of inadvertent biomimicry... we didn't even know that insects had already evolved a gear system long before we did!

insect-leg-gears-1Scientists in the United Kingdom have discovered an insect that uses a gear mechanism to jump.  They hypothesize that the mechanical advantage from the gear system enables them to jump quickly with

laminar flowTeachable Moment: Great science experiments are indistinguishable from magic and this little video is a wonderful example using viscocity to demonstrate laminar flow.

As explained on the web site: http://panda.unm.edu/flash/viscosity.phtml

The Reynolds number R is the dimensionless combination:

              R= ρνR
η

in which ρ is the density, ν the speed of the fluid, R the size of the flow, and η the viscosity. When R ≤ 1, friction dominates inertia and the fluid flows in layers (laminar flow).Here we are using corn syrup which has a viscosity of 5 (Pa s); its viscosity is 5000 times that of water, and the Reynolds number R is less than unity.This experiment is being demonstrated by Kevin Cahill for his Biophysics II students.The couette cell used in this experiment was fabricated by John DeMoss in the Machine Shop of the Department of Physics and Astronomy at the University of New Mexico.

Teachable Moment:  Edison's wonderfully eclectic task list is a reminder that we can risk stifling creativity and innovation if we insist people focus on one task at a time.  Of course, the challenge then becomes competing those tasks.

Teachable Moment:
Great videos that explain advanced engineering concepts in everyday devices. I especially like the tear down videos.

Make called Bill a "brilliant science-and-technology documentarian", whose "videos should be held up as models of how to present complex technical information visually" Wired called them "dazzling." Scientific American's blog called him a "smart, easygoing everyman with a firm understanding of the science." You can see 10 of his best videos below. He takes apart an LCD monitor, demonstrates how fiber optic cables work, rips up a hard drive, explains the wonder of a quartz wrist watch, solves the mystery of black boxes, blows up a light bulb filament, reveals how amazing a pop can tab truely is, shows why a cell phone looks like it does, and explains why you always seem to be in the slowest line.

Teachable Moment: Sometimes the best person to teach a challenging concept is someone who has recently learned it and wants to share their own excitment of the discovery. I can't wait to see this video library grow.

 

MIT has launched an initiative encouraging its students to produce short videos teaching basic concepts in science and engineering. The videos — aimed at younger students, in grades from kindergarten through high school — will be accessible through a dedicated MIT website and YouTube channel. A subset of the videos will also be available on Khan Academy, a popular not-for-profit educational site founded by an MIT alumnus.

Equations that Rule your World logoTeachable Moment: This is a great synthesis of how a series of clearly important, yet seemingly disparate, equations have been used together to provide us modern conveniences.

Without equations, most of our technology would never have been invented. Of course, important inventions such as fire and the wheel came about without any mathematical knowledge. Yet without equations we would be stuck in a medieval world.

Teachable Moment: Anyone interested in history of science would love these archives.  From his notes deriving his famous equation to his love letters this is a treasure trove of information that humanizes this great scientist.

The Einstein Archives Online Website provides the first online access to Albert Einstein’s scientific and non-scientific manuscripts held by the Albert Einstein Archives at the Hebrew University of Jerusalem, constituting the material record of one of the most influential intellects in the modern era. It also enables access to the Einstein Archive Database, a comprehensive source of information on all items in the Albert Einstein Archives.

DIGITIZED MANUSCRIPTS

From 2003 to 2011, the site included approximately 3,000 high-quality digitized images of Einstein’s writings. This digitization of more than 900 documents written by Einstein was made possible by generous grants from the David and Fela Shapell family of Los Angeles. As of 2012, the site will enable free viewing and browsing of approximately 7,000 high-quality digitized images of Einstein’s writings. The digitization of close to 2,000 documents written by Einstein was produced by the Albert Einstein Archives Digitization Project and was made possible by the generous contribution of the Polonsky Foundation. The digitization  project will continue throughout 2012.

Teachable Moment: I love this web site for ideas of projects to show students.  The philosophy of open source and the clarity of the instructions make this an indispensable resource for great STEM projects.

Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. The seeds of Instructables germinated at the MIT Media Lab as the future founders of Squid Labs built places to share their projects and help others.

Teachable Moment: Great resource for ideas for science projects.

Science Buddies mission is to help students from all walks of life to build their literacy in science and technology so they can become productive and engaged citizens in the 21st century. We have created personalized learning tools, over 15,000 pages of scientist-developed subject matter (including experiments based on the latest academic research), and an online community of science professionals who volunteer to advise students. We also provide resources to support parents and teachers as they guide students doing hands-on science projects. Representing much more than a website, Science Buddies quickly and efficiently matches students with the information that will hold their interest and answer their questions. We provide a bridge between scientists and students, giving students access to current scientific research and simultaneously giving scientists a way to reach out to young people interested in their fields.

Teachable Moment: Great little collection of fun science questions....

Did you ever wonder why a camel has a hump? If you can really tell the weather by listening to the chirp of a cricket? Or why our joints make popping sounds? These questions deal with everyday phenomena that we often take for granted, but each can be explained scientifically.
