Electroplating (High School curriculum lesson)

Students will create thin layers of copper and nickel in an electrochemical reaction to understand how an electric current passed through an ionic solution will result in a chemical reaction which will separate materials. In addition students will also explore the various parameters effecting deposition, morphology, and thickness of the film to be deposited.

Electrodeposition (High School curriculum lesson)

This lab is designed to introduce students to the applications of forcing a chemical reaction using an electrical current. Students will discover how a flow of electrons allows cations in solution to revert to a solid state while plating an object. Students will become familiar with the process which allows the ions of the plating solution to be replenished, and how this results in a loss of mass for the solid metal electrode.

Understanding Wave Motion and Power Loss (Middle and High School curriculum lesson)

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 lesson connects with the Big Ideas in Nanoscale Science (Stevens et al, 2009; NSTA Press) Big Idea – Forces and Interactions (All interactions can be described by multiple types of forces, but the relative impact of each type of force changes with scale. On the nanoscale, a range of electrical forces, with varying strengths, tend to dominate the interactions between objects.)

Lab on a Slab (High School curriculum lesson)

Microfluidics is a technique for manipulating liquid samples. With one drop of liquid sample, small devices and channels can be used with nanoparticles for sensitive detection of chemicals. In this lab, students will create a fluidic device with agar gel and use it to test and diagnose three “patient’s” samples for pH, starch, and peroxide content

Snake Oil (High School curriculum lesson)

The purpose of this activity is to use electrochemistry techniques to generate colloidal silver and then utilize the colloidal silver to determine if the growth of the bacteria Saccharomyces cerevisiae or Escherichia coli can be inhibited.

Big vs. Little - Micro to Nano (Elementary School curriculum lesson)

Children will explore the concept of size by comparing and categorizing objects, then constructing various sized structures. Beginning their understanding of big and small will be important as they develop an understanding of the nanoscale in later grades.

Silver and Bandages (High School curriculum lesson)

This lab is designed to have students develop and implement their own experiment to test the antimicrobial properties of silver nanoparticles. Students will be required to document and communicate the entire process via their scientific notebook. Students will also consider the implications and applications of nanotechnology by evaluating scientific literature.
