Tardigrades are amazing creatures that can withstand the most extreme conditions on Earth, as well as the vacuum of space! This unique and charismatic animal has the ability to survive in a variety of situations. In today's program, Exploratorium scientist Karen Kalumuck will continue our programming about life in extreme environments as it relates to the search for 'habitability' on Mars. Just outside the hum and buzz of San Francisco, there's a hum and buzz of a different sort.
It's the sound of thousands of acres of almond crops being pollinated by bees—bees in such demand
that they must be trucked in from as far as Texas. Almond grower Dave Phippen explains why.
keeping this winged labor force happy and healthy is a vital but tricky business. Hayes Valley Farm is a community-run farm on a former freeway
in the middle of San Francisco. The land was slated for condo
development but the plan was put off when the economy slumped.
Out of the ashes of that dream arose a utopia of a different sort; a
suspended reality where fruit trees are grown on what was once a
freeway on-ramp choked with cars. Now there are flowers growing
out of the double yellow lines, and constant opportunities for
children and adults to learn how to grow food and to get dirty doing
it. Although the farm has only an "interim use" permit, meaning
that it can't last forever, farmers Zoey Kroll and Jay Rosenberg
know that the enduring harvest of this project--the truth that even
the most outlandish-sounding things are possible if we make them
so--will far outlive the farm itself.
Most things won't burn on Mars—after all, the main ingredient in the Martian atmosphere, carbon dioxide, is used in fire extinguishers on earth. So how would one create fire without oxygen? Use metal!This slow motion footage shows magnesium burning within a block of dry ice.
TI staff educator Eric Muller demonstrates a “cool” thing to do with dry ice, and it even relates to the standards!
TI staff educator Eric Muller hits me up for change, and then demonstrates a neat science activity using dry ice.
Our Exploratorium team talks to scientists from POLENET (Polar Earth Observing Network). In this interview from in front of the Canada Glacier in Antarctica’s Taylor Valley, Hassan Basagic from Portland State University describes the essential role of polar glaciers in supporting the bare-bones ecosystems in the Dry Valleys. Sonoma Valley farmer Bob Cannard doesn't fight nature: he collaborates with it. The result is bountiful fields of healthy, beautiful plants, some of which end up in the kitchen at Alice Waters' Chez Panisse restaurant in Berkeley, California. Here Bob speaks eloquently about appreciating and respecting nature. As he says, "it's simple...it's all right there before you." Bob Cannard, a Sonoma Valley farmer explains how compost is generated, both by nature and by human gardeners. Cannard creates a special compost 'tea' to use on his bountiful crops
