For thousands of years, Indian women have created these elaborate geometric designs using a variety of natural materials—flowers, spices, sand, and natural pigment—to mark auspicious occasions, celebrations, and milestones. Join Exploratorium educator Ken Finn as he unlocks the mystery behind the black sand (a.k.a. magnetite) at Ocean Beach. This piece explores the origin of magnetite in the Sierra Nevada mountains, its journey down the Sacramento and San Joaquin rivers to the Bay, and the interesting physical properties of this mineral, plus some fun things you can do with it. This After Dark event, which explored the science behind slowing down, included artist Joe Mangrum, who created a sand mandala on the floor of the museum. In this timelapse video, shot over 8 hours, you can see the full arc of the work.
Slow motion footage of Pyrograph, a work by Earl "Dodger" Stirling that has been described as a cross between Dante's Inferno and the Foucault Pendulum. Like a fiery version of the Exploratorium's classic Drawing Board exhibit, Pyrograph swings a pendulum across a sandy, flaming cauldron and traces out oscillating patterns in colorful fire.
Aeolian Landscape is an exhibit in which a miniature wind-swept desert landscape is recreated by an electric fan and finely ground sand that mimics the process of wind picking up and depositing small particles. Visitors can change the direction of the fan, influencing the shape of the dunes. The two Mars Rovers are alive and well after surviving their second Martian winter. Come and see photos of discoveries they made during their third year on Mars, with Exploratorium Senior Scientist Paul Doherty.
Join Exploratorium physicists Paul Doherty and Stephanie Chasteen as they examine the past, present, and future of climate change. Watch as Paul and Stephanie demonstrate how you can look at a slice of climate from the past, what a sediment core might look like, and the secrets hidden in an ice balloon! An clip of the Aeolian Landscape exhibit by artist Ned Kahn. Blowing air sculpts sand into an ever-changing landscape. On December 11, 2005, Opportunity, one of the twin rovers exploring Mars, celebrated its first Martian birthday. Opportunity had been on the red planet 687 Earth days, which is one Martian year. (A year is the time it takes a planet to make a complete loop around the sun). Join us for a look back over the those 687 days of discovery: what we learned, what we saw, and what questions remained unanswered. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: CD cases!
