  3. Spectrophotometry of Metal Nanoparticles

    16 Jun 2020 | | Contributor(s):: Chris Kaus, James J Marti, NNCI Nano

    This activity has students chemically synthesize gold and silver nanoparticles, measure the spectra of light absorption and transmission by these particles, compare these spectra to those of known-sized particles, and then estimate the size distribution of the particles they have made. By using...

  4. Efficiency of Nitinol Wire

    11 Jun 2020 | | Contributor(s):: John Nice, NNCI Nano

    This lab activity focused on nitinol or muscle wires  which are shape memory alloys. These wires can be used to lift a weight up a height. Students will explore how the work performed lifting a load with the nitinol wire compares to the energy pumped into the wire by an electrical current....

  7. Understanding Waveguides: Light at the Nanoscale

    13 Feb 2020 | | Contributor(s):: Marilyn Garza, NNCI Nano

    There are three lessons for this activity that help students understand how light can travel through a waveguide for communication purposes. Students will first explore the angle of refraction. Next they will create a gelatin waveguide to explore issues associated with light and waveguides....

  8. NNCI Reference Sheets

    11 Feb 2020 | | Contributor(s):: Joyce Allen, Nancy Healy, NNCI Nano

    This is a series of 5 reference sheets for high school students that have a summarized version of important concepts for courses in: Physics, Physical Science, Chemistry, Biology, and Genetics.  These are two sided, with one side introducing nanotechnology and the other containing facts,...

  9. Understanding Wave Motion and Power Loss

    10 Feb 2020 | | Contributor(s):: Richard Moore, Angela Berenstein, NNCI Nano

    This lab is designed to help students understand how light waves interact with matter. This activity is analogous to light traveling through optical media having different indices of refraction (densities). This is a two part lesson. In part 1 students use slinky and snaky toys to explore wave...

  10. Design Challenge: Incorporating Shape Memory Alloys into Rube Goldberg Devices

    05 Feb 2020 | | Contributor(s):: Joyce Allen, NNCI Nano

    This lesson consists of two parts. In Part 1, students determine which of set of wires is a unique metal alloy called Nitinol. Nitinol is called a shape memory alloy (an SMA) because it can “remember” its original shape under certain conditions after being bent, twisted, or...

  11. Solar Ovens: Understanding Energy Transfer

    28 Jan 2020 | | Contributor(s):: Christina Levyssohn-Silva, NNCI Nano

    At the end of this lesson, students will understand that solar energy radiates from the sun to the Earth and gets trapped within the oven. Students will be able to explain how the thermal energy flows from the hot air to the cold water via conduction and will indicate that this would continue...

  12. Properties of Fluids

    21 Jan 2020 | | Contributor(s):: Astrid Hernandez, NNCI Nano

    This lab explores the properties of water flow. This inquiry-based lab consists of 2 sections: the Guided Lab Activity and the Going Further (research) portion. The guided lab activity, performed on the first day, is designed to help students observe and understand the way fluids interact with...

  13. Nanomotors: Nanoscale Propulsion

    15 Jan 2020 | | Contributor(s):: Paul Longwell, Chantelle Smith, Stephen Stillanos, NNCI Nano

    This lesson is designed to engage students in hands-on experiments that explore nanoscale propulsion principles and guide students in recognizing and analyzing differences between macroscale and nanoscale propulsion systems.

  14. Nanoparticles Land to Ocean: Understanding the Effect of Nanoparticle Pollutants

    15 Jan 2020 | | Contributor(s):: Chloe Figuerido, NNCI Nano (editor)

    Pollution, both macroscopic and microscopic, is an important environmental issue for aquatic ecosystems. For this lab, students will model how nanoparticle pollution travels from land to water. This lab isa 2-part series of labs designed to help students understand the effect that nanoscale...

  15. Quantum Dots: Real-world Particles in a Box

    15 Jan 2020 | | Contributor(s):: Joyce Allen, NNCI Nano

    The purpose of this activity is to show that nanosize particles of a given substance often exhibit different properties and behavior than macro or micro size particles of the same material. The property studied in this activity is the absorption and reflection of light which is based on energy...

  16. Doping to Create a Semiconductor: Changing conductive properties through diffusion

    14 Jan 2020 | | Contributor(s):: Kaye Sheets, NNCI Nano

    In the semiconductor industry scientists take advantage of diffusion to “dope” or introduce atoms into a silicon wafer to change its conductive properties. The lesson simulates the diffusion of a gas phase substance (ammonia) into a solid substrate (gelatin)  and compares the...

  17. Hiding Behind the Mask: A Fabrication Activity Focused on Etching

    13 Jan 2020 | | Contributor(s):: John Gomm, NNCI Nano
