Self Assembly/Bone Regrowth (Episode #705Z)

PBS Kids: Wed, Jul 11, 2012 -- 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.

Gecko Feet/Nasturtium Leaves (Episode #704Z)

PBS Kids: Wed, Jul 4, 2012 -- 4:00 PM

Gecko Feet - Jennifer and Nooshin like rock climbing. They wonder how some lizards can climb rocks so easily. They visit the Lawrence Hall of Science in Berkeley and compare the climbing ability of different lizards. They notice that the best climbers are geckos. They visit a lab at the University of California Berkeley to find out why, learning that special, nanoscale hairs on gecko feet are the secret to their amazing climbing abilities. Nasturtium Leaves - Jasmine and Melinda wonder why water beads up on some plants and not others. They head to San Francisco's Exploratorium, where they learn that surfaces at the nanoscale aren't always smooth, and that nano hairs on nasturtium leaves cause them to be water repellent. The girls collect other plants with hairy leaves and test their ability to repel water. They take some samples to Stanford University for up-closing imaging and compare the structure of nasturtium leaves to water-resistant fabric.
