This is a recording of a NISE Network online brown-bag conversation held in 2014 and focuses on the applications and scientific background behind the following NanoDays 2014 kit activities: • Exploring Materials - Oobleck • Exploring Materials - Ferrofluid Presented by: Lizzie Hager-Barnard of the Lawrence Hall of Science For more information, and for a link to the recording, please see the Resources section of this page.
"Exploring Materials—Oobleck" is a hands on activity in which visitors investigate the properties of a cornstarch and water mixture and test its ability to protect from impacts. Visitors learn that similar nanomaterials can be used in new personal protective equipment.
“Kitchen Chemistry” is a live stage presentation about recognizing and exploring the science that we practice every day in our very own homes. We take a look at the chemistry behind a seemingly simple bowl of spaghetti – from boiling water, to the behavior of starches and lubricants both on the macro- and nanoscale, to the nanosensors that determine our perception of taste and smell; how cooking is a complex chemistry, and how we are complex in the ways we experience our food. The presentation consists of multiple demonstrations, many including audience participation.
These 'Do It Yourself' Nano activities and experiments allow families to experience and learn about nanoscale science, engineering, and technology at home or on the go! They are are designed to be done in the comfort of your own home. Each activity includes lists of widely available, inexpensive materials, step-by-step instructions, and detailed explanations. Go ahead, give 'em a try!
