As post-Halloween sugar highs ebb and trick-or-treat stashes wane, the days of pre-packaged, ready-to-eat treats give way to the smells of freshly-baked bread, pies, cakes, gingerbreads, and a variety of other family favorites. Indeed, as the year winds down and the days shorten, the kitchen can become an epicenter of activity. With classroom potlucks, family dinners, and a string of potential holiday gatherings dotting the calendar for November and December, the making…

Shortly after finding out she was one of thirty teachers selected to participate in a Zero-G flight as part of the Weightless Flights of Discovery Program, sponsored by Northrop Grumman, Erin Moore, an eighth grade teacher at Lincoln Avenue School in Illinois, gave Science Buddies an inside look at her sudden shift from "teacher" to "astronaut" - in her student's eyes. Her awareness that her students had already put her in orbit, left her faced with a philosophical decision: correct their…

Earlier this week, I talked about a paper chromatography project that offers a perfect opportunity for younger students to observe the pigmentation of Autumn leaves and then a make-your-own-markers project that can turn a pile of leaves into a set of homemade art supplies.
For a different spin on fall foliage, the "Leaves and Light" project (no longer available) explores the two kinds of chlorophyll present in plants and the degree to which the color and wavelength of light affects the…

Mashing a pile of fall leaves offers a colorful demonstration of "extraction" and sets the stage for paper-towel-based chromatography.
One of the things that I often miss living in the Bay Area is the definitive visual change of seasons. Having spent many years in Appalachia, I grew up with the splendor of Autumn unfolding around me each September, the array of intense reds and golds giving way to barren branches poised to hold ice and snow through the winter months. It's very…

Does it take you a bit of time to settle in once the time changes? Did you or members of your family wake up earlier the day after the time changed? Do you notice already the changes in available light during the day? Do you know "why" the time changes? Did we gain an hour or lose an hour? Aren't there just 24 hours... regardless?
It's interesting to note that while observing Daylight Savings Time is not mandatory in the United States (and not even all states participate), Daylight Savings…

I wrote earlier about my trek to the northeastern corner of California to attend the Golden State Star Party. My objective was to photograph a galaxy, and after checking out the pristine skies during my first night of observing, I selected my targets: M81 and M82, a…
