Surface Area/Stained Glass (Episode #703Z)

PBS Kids: Tue, Sep 25, 2012 -- 4:00 PM

Surface Area - After discovering that ordinary flour dust can be explosive, Lara and Anushua explore the importance of surface to area to volume ratio at the Science Museum of Minnesota. They conduct soda explosion experiments in the museum's Big Back Yard, investigating how surface area affects reactions. Finally, they visit the University of Minnesota where they learn how scientists are developing more affordable solar cells with nanotechnology that increases the cells' surface area. Stained Glass - Alettie and Yvonne visit the Glass Experience exhibit at the Museum of Science and Industry in Chicago and learn that nanoparticles are responsible for the colors in some medieval stained glass. The girls are surprised to learn that nanogold makes glass red! They go to Northwestern University to explore the relationship between size and color of nanoparticles. They create different sizes of gold and silver nanoparticles to produce a variety of colors, which they use to make their own works of art.

Hockey Sticks/Butterfly Wings (Episode #702Z)

PBS Kids: Tue, Sep 18, 2012 -- 4:00 PM

Hockey Sticks - Nicholas and Jordan love hockey. They know that carbon nanotubes are used in some hockey sticks, but aren't sure how the tiny structures change the equipment. They head to Boston's Museum of Science to learn more about carbon nanotubes. Then, they put their sticks to the test on the ice. Finally, with help from scientists at Harvard University, they compare the tensile strength of the sticks and use powerful microscopes to "see" carbon nanotubes. Butterfly Wings - Emily and Julie check out the Magic Wings Butterfly House at the Museum of Life and Science in Durham. They wonder why butterfly wings are so colorful. They learn that iridescence in some butterfly wings - like the iridescence of soap bubbles - results from their structure. At Duke University, the girls learn how to determine whether colors in wings are the result of pigment or nanoscale structures. They test butterfly wings and learn that blue iridescence is due to structure, not pigment.

PBS Kids: Tue, Sep 11, 2012 -- 4:00 PM

* What's Nano? Ebony and Jasmine catch the Amazing Nano Brothers Juggling Show at Museum of Science in Boston. The show gets them thinking, "How big is a billion? And how small is a billionth?" They search Boston for examples of a billion. Then they visit laboratories at Harvard University to find examples of nanoscale objects on their quest to "see" a nanometer.
* Where's Nano? Regina, Linda, Harrison, Jared, Lorenz, and Randi, visit the "Zoom In" exhibit at the Morehead Planetarium and Science Center in Chapel Hill. They wonder what examples of nanoscale science and technology they can find in their everyday lives. Their nano "scavenger hunt" takes them to the University of North Carolina Chapel Hill, where a scientist helps them print images of nanoscale structures. The kids then create a visual representation of their findings to display at the science center.
