PBS Kids: Sat, Jan 12, 2013 -- 4:00 PM

Water Clean-Up - Taylor and Gabe go to the Franklin Institute in Philadelphia and learn that nano-iron is being used to neutralize toxins in ground water. They collect soil samples from a contaminated site, then take them to Penn State University to test the efficacy of nano-iron treatments. Nanosilver - Sarah and Mande visit the Sciencenter in Ithaca and learn that nanosilver is used in some socks to kill bacteria, keeping them odor-free. They wonder if the nanosilver in socks leaches out when you wash them, causing potential harm to beneficial bacteria and the environment. They buy two different brands of nanosocks and wash them. Then they take the socks and their wash water to Cornell University to test their effects on common bacteria.

Self Assembly/Bone Regrowth (Episode #705Z)

PBS Kids: Sat, Jan 5, 2013 -- 4:00 PM

Self Assembly - Keely and Connor learn about self-assembly at the Children's Museum of Houston. The museum staff suggest they visit Rice University, where scientists use self-assembly to make things at the nanoscale. At Rice, a scientist helps the kids use self-assembly to make and "pop" microcapsules. The kids then try out a similar technique at home, encapsulating chocolate sauce, mint and other flavors in alginate beads to serve on ice cream. Bone Regrowth - Kobel, Nathan, and Adam go to the Oregon Museum of Science and Industry (OMSI), where they learn that scientists are using nanotechnology to help regenerate nerves and bones. A scientist from Brown University explains that a solution of nanotubes and minerals is injected into the fracture and forms a scaffold to encourage bone regrowth. The kids want to know why both ingredients are needed to repair the bone. They try solutions with different amounts of each ingredient on sponges and test how much weight each treated sponge can support.
