  • Mechanical gears found in living creature

    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! Scientists 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 quic ...

  • Laminar Flow

    Teachable 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 whic ...

  • Periodic table of Periodic Tables

      Teachable moment:  just because the basic periodic table format designed by Mendeleev is the most commonly taught format, it doesn't mean it works for everyone, this image explores and illustrates the various ways people have tried to organize the elements.   Reference: http://www.keaggy.com/periodictable/  ...

  • Interactive Physics Simulations

     Teachable Moment: Great, tool for simulating real world experiments. I look forward to seeing this evolve. Fun, interactive, research-based simulations of physical phenomena from the PhET™ project at the University of Colorado. Reference: http://phet.colorado.edu/ ...

  • Michael Faraday Watches a Candle

    Teachable Moment: A beautiful reminder from Michael Faraday of the power of observation:  Observe....everything. Think about...everything. And don't interfere. Then do it again until you are sure you have it. We take for granted that we understand the simple, and have moved on to the less simple. Michael Faraday gave an annual lecture on the burni ...

  • Protein Synthesis - An Epic on the Cellular Level

    Teachable Moment: Memorable illustration of protein synthesis, acted out. Directed in 1971 by Robert Alan Weiss for the Department of Chemistry of Stanford University and imprinted with the "free love" aura of the period, this short film continues to be shown in biology class today. It has since spawn a series of similar funny attempts at vulgariz ...
