Many plastics are in our oceans due to pollution, including ocean dumping and land runoff. Sunlight and alkaline ocean water break these plastics down into small particles, many are nanoscale in size. These nanoparticles can easily enter our cells. Students examine if and how these...
Help or Hype: The Ethics of Bio-nanotechnology
11 Jan 2017 | | Contributor(s):: Samantha Andrews
This lesson explores the ethical concerns related to bio-nanotechnology. Bio-nanotechnology is the application of nanotechnology to living things. This ranges from the creation of pharmaceuticals to medical devices. While scientists have created many life-saving treatments ethical concerns, such...
Lines on Paper
11 Jan 2017 | | Contributor(s):: Joshua LaForge
Students will learn how scientists use a process called X-ray diffraction to figure out the structure of things that are too small to see such as atoms, molecules, and crystal structures.This lab will help students understand how light is bent into different directions as it interacts with small...
Mixtures and Nanotechnology
11 Jan 2017 | | Contributor(s):: Joyce Palmer Allen
The purpose of this unit is to help students make the connection that the classification of mixtures is based on the size of particles. This connects to two of the Big Ideas in Nanoscale Science and Engineering (Stevens, Sutherland, and Krajick 2009). The first is Size and Scale or factors...
Nanotechnology Invention and Design: Phase Changes, Energy, and Crystals
11 Jan 2017 | | Contributor(s):: Daniella Duran
This 3-part lesson introduces the nanoscale effect of various energy inputs on the crystal lattice of a smart material, Nitinol, and then invites students to become nanotechnology inventors. Students will first explore how energy exchanges lead to solid-state phase changes at the macroscale and...
Right Tool for the Job
The purpose of this lesson is to encourage students to think about how using tools helps them gather information about the world around them. This is especially important at the nanoscale, where the objects are too small to be seen and the information we gather depends on the tools that we...
Synthesis and Characterization of CdSe Qunatum Dots
11 Jan 2017 | | Contributor(s):: Nicholas Blake
In this laboratory, students will study how surfactant-based chemistry can be used to synthesize CdSe quantum dots and study how the size of the quantum dots can be controlled by varying reaction time. The laboratory will demonstrate how the color of these quantum dots can be connected to...
Taking a Closer Look at Objects
11 Jan 2017 | | Contributor(s):: Georgia Institute of Technology
For students to understand their world they often need to use tools to gather information. Some tools will help them see parts of their surrounding world that they would otherwise miss. These tools include magnifying glasses and microscopes. The lesson can be conducted as...
Wet Etching in Nanofabrication
11 Jan 2017 | | Contributor(s):: Manuel Casillas
This lab will help students understand how chemical reactions are used to create the specific shapes on surfaces of crystalline materials, which make up functional components within electronics. The fabrication of electronic devices is now reaching into the nanoscale with the capability of more...
Learning About Surface Area and Volume
The purpose of this lesson is to help students extend their knowledge of area, perimeter, and volume to include surface area. The understanding of these concepts begin in the elementary grades and helps students understand events such as why a hot potato cools down quicker when it is...
Sometimes We Need Big Numbers
The purpose of this lesson is to help students visualize how small a nanometer is by relating the size to the numbers- millions, billions and trillions and then relating those numbers to how small particles of matter are. It begins to lay the foundation for future learning about atoms in the...
Silver Nanoparticle Synthesis, Spectroscopy, and Bacterial Growth
11 Jan 2017 | | Contributor(s):: Pennsylvania State University
Students will learn about the differences in physical propoerties at the nanoscale as compared to the same materials at the macroscale. The students will demonstrate the appropriate use of a spectrophotometer and will convert between different units of measurement. This unit assists students in...
What's the Smallest Thing You Know?
The book What’s Smaller Than A Pygmy Shrew? by Robert E. Wells helps students see that a pygmy shrew is among the tiniest of mammals and that a ladybug is even smaller. But in the book, they will also find even smaller things that they ordinarily do not see. This is the...
Introduction to Creative Problem Solving in Nanotechnology
10 Jan 2017 | | Contributor(s):: Joseph Nunn
This lesson serves as an introduction to the field of nanotechnology by discussing its real-world implications in light of current economic issues and conditions. The lesson is performed using the Creative Problem-Solving format and serves as a method to encourage debate on current topics.
Silver Nanoparticle Socks
10 Jan 2017 | | Contributor(s):: Pennsylvania State Univeristy
This lab will allow students to use the pure silver nanoparticles they synthesize to create antibacterial socks. They will compare their socks with socks that have been treated with a commercial silver spray, socks that have been treated in a factory, and a control that was not been...
Is measuring an art or a science?
09 Jan 2017 | | Contributor(s):: Monica Hochstein
Nanotechnology occurs on the scale of 1-100 nanometers (in one direction). There have been numerous predictions about the growth in nanotechnology production and its impact on manufacturing in the near future. Manufacturing and commercial exchange of nano products will create a need for...
Making a Liquid Crystal Thermometer
09 Jan 2017 | | Contributor(s):: Rano Sidhu
Liquid crystals are matter that has properties between those of a liquid and a solid. Liquid crystals may flow like a liquid but have crystals like a solid.colors of the objects are Color is the outcome of various light properties: absorption, refraction, or reflection. In the case of liquid...
Powers of Ten with the Blue Morpho Butterfly
09 Jan 2017 | | Contributor(s):: Nancy Healy, Marilyn Garza
This activity is designed to help students understand the concept of scale and magnification when examining a Blue Morpho butterfly wing. The activity requires the use of a scanning electron microscope (SEM) but images are provided if there is no access to an SEM.
Size and Scale - Learning about measurement
09 Jan 2017 | | Contributor(s):: NNIN RET
Students will visualize the order of numerical properties of objects from the nanoscale to visible scale using exponents and decimals. Students will make size comparisons of objects. Students will develop an understanding of how small a nanometer is in comparison to common objects. They will...
