Evolution of Technology in Education

I am going to be writing a series on how to use technology tools in the classroom (with a focus on science, of course)

To wet your appetite, I would like to turn you on to the idea of using QR (Quick Response) codes, usually square looking bar code thingys.  to engage your students and allow them to use their mobile devices/netbooks/ or anything with a webcam to access your content. See the following links to get more information on these devices.

Biochemistry of Cooking

A biochemist and cook explains that cooking is all about chemistry and knowing some facts can help chefs understand why recipes go wrong. Because cooking is essentially a series of chemical reactions, it is helpful to know some basics. For example, plunging asparagus into boiling water causes the cells to pop and result in a brighter green. Longer cooking, however, causes the plant's cell walls to shrink and releases an acid. This turns the asparagus an unappetizing shade of grey.

What does it take for one person to change the world? How about not waiting and start doing.
