The holidays are a time for giving. In the Bay Area, they're also a time for learning.
We've put together a list of the Bay's best science-centric holiday traditions, activities and exhibits. From riding a glowing gondola to the annual Christmas Bird Count, consider spicing up your holidays with a little science and nature awesomeness.
California Christmas Bird Counts
Run through Jan. 5. Free
For over 100 years, naturalists have been spending their holidays trekking through parks, mudflats and city streets to count birds.
The ritual began in the year 1900, when ornithologist Frank Chapman proposed an alternative to the Christmas Day bird hunts that were popular at the time.
By the turn of the century, conservationists were already concerned about declining bird populations. So Chapman and few dozen birders from Pacific Grove, California to New York City logged nearly 20,000 sightings across 89 species in the first bird-census of its kind.
Through the years, holiday bird counts sponsored by Audubon have become a tool for scientists to monitor the health of bird populations and habitats. Data from the counts inform decisions made by the U.S. Fish & Wildlife Service.
Christmas Bird Counts will be held in Monterey and San Francisco on Thursday, Dec. 27; in Sonoma Valley on Friday, Dec. 28; in Marin on Saturday, Dec. 29 and in western Sonoma County on Sunday, Dec. 30.
Runs through Jan. 20. $29.95 adult, $19.95 youth
The Exploratorium is hosting another of its "Curious Contraptions," exhibits, featuring mechanized sculptures called automata. This year's theme is fairy tales.
The pieces are exquisite but they can also teach you about the basics of mechanical movement.
"For instance when you play with the mermaid," says curator Nicole Minor, "you get a sense of these little cams and gears, and a little pulley system that’s moving her arms forward and backward, and her tail side to side."
And, if you fall in love with automata, you can try your hand at making your own in the Exploratorium's Tinkering Studio.
While you're there, check out Glow, an installation of fabulous light sculptures and creations.
