ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************



















An online resource to increase learner engagement and
educator content knowledge is available free of charge. “As Many Exceptions As
Rules” tells the stories of organisms that break biological rules or norms in
order to survive and thrive. Through these stories, the core concepts of the
science are reinforced.

 

The resource can be accessed at :   http://biologicalexceptions.blogspot.com

 

Posted weekly, each story includes pertinent vocabulary with
etymology, interesting questions to spark discussion, links to the reports from
the latest research on the subject being discussed, and a list of online
resources for more information and classroom activities.

 

Stories from the last month include: a series on the differences
between toxins and venoms and the exceptions – venomous mammals, salamanders
that deliver venom by sticking their ribs through their skin, plants that can
kill you just by standing near them, and how some birds are toxic due to the
insects they eat.

 

The most recent post begins a summer series of interesting
biological questions – humans are some of the weakest organisms when it comes
to holding their breath- whales and seals are better and have special proteins
to submerge longer. But other organisms can hold their breath for 12 hours or
more, or even up to 50 years!
