Sand and Multiple Light Scattering
23 Aug 2021 | Teaching Materials | Contributor(s): Denise Kapler, NNCI Nano
Nanoparticles and other nanoscale materials are often analyzed through the specialized use of light scattering. Several techniques use the light scattered from small particles to estimate their size distribution; these techniques employ light absorption, laser diffraction, and dynamic light...
A Look into the Nanoworld: An introduction to Nanoscale Science and Engineering
23 Aug 2021 | Teaching Materials | Contributor(s): NNCI Nano, Jackie Smith
This is a four-part lesson that has students explore the nanoscale. The lesson includes: size and scale, metric system and conversions, measurement, nanotechnology applications, and careers in nano-science. The activities can be done in groups of 2-4 and requires viewing of videos.
Now You See It, Once Filtered, Hope You Don't
07 Jul 2021 | Teaching Materials | Contributor(s): Patricia Kuberra, NNCI Nano
Water is a valuable natural resource and resides in multiple reservoirs: the cryosphere, geosphere, biosphere, and atmosphere. Water quality is often jeopardized by various contaminants but can be improved by removing contaminants from the water whether they are macro (dirt and debris,) micro...
Transistor Mania: Modeling Electron Flow
17 Jun 2021 | Teaching Materials | Contributor(s): Meghan Saxer, NNCI Nano
This activity is designed to help the students understand the significance of transistors in their lives. Students will learn how current research on nanoscale transistors is making their favorite electronic devices (i.e., cell phones, gaming devices, computers, etc.) faster and more powerful....
Particle Size and Spectral Analysis of AgNO3 and Cu: Design Challenge Activity
17 Jun 2021 | Teaching Materials | Contributor(s): John H. Hitchcock, NNCI Nano
When the traditional silver nitrate reduction by copper is performed, students are often puzzled by the black appearance of the silver when it first is observed. In this activity, students will research two questions about the reaction, develop a viable system of gathering data, and investigate...
