Teaching middle school or high school students? Use these resources to help kids understand what nanotechnology is and how it may impact their lives. You might start by watching Mark Ratner's seminar A Gentle Introduction to Nanotechnology and Nanoscience. Check out the various animations that we have to explain nanoscience concepts. Try running a simple tool online, such as CNTbands.

Do you have your own nano teaching materials? Post them on the nanoHUB for all to see!
3D Molecular Models
out of 5 stars
21 Jun 2007 | | Contributor(s):: Nicholas Vargo
This animation was created as part of the Children's Museum Nanotechnology Exhibit to give the viewer an idea of what objects look like at the nano-level. The molecules range from something as small as caffeine to major proteins and viruses.Nicholas Vargo created this kiosk presentation as an...
General Introduction to Nanotechnology
20 Apr 2007 | | Contributor(s):: Hyung-Seok Hahm
This is an 80 second movie clip. The camera zooms in from a computer to molecules with a narration.The design goals are - Give a smooth introduction to nano-world- Deliver ideas of how small nano-scale objects are with a zoom-in- Inform that nanotechnology is related to everyday thingsProduced...
Introduction to Scanning Tunneling Microscopy
This is a 60 second movie clip with an introduction to Scanning Tunneling Microscopy(STM). Design goals are - Give an idea of what STM looks like- Provide an overview of what STM does and how it worksProduced by Imran Sobh and Hyung-Seok HahmAs part of instructional materials by National Center...
Operation of Scannig Tunneling Microscopy
This is a 60-second movie clip with a narration of how Scanning Tunneling Microscopy(STM) operates. Produced by Eric Meyer, Imran Sobh and Hyung-Seok Hahm Beckman InstituteUniversity of Illinois at Urbana-Champaign As part of instructional materials by National Center for Learning and Teaching...
Quantum-dot Cellular Automata (QCA) - Memory Cells
03 Feb 2006 |
Scientists and engineers are looking for completely different ways of storing and analyzing information. Quantum-dot Cellular Automata are one possible solution. In computers of the future, transistors may be replaced by assemblies of quantum dots called Quantum-dot Cellular Automata (QCAs).This...
Quantum-dot Cellular Automata (QCA) - Logic Gates
An earlier animation described how "Quantum-dot Cellular Automata" (QCAs) could serve as memory cells and wires. This animation contnues the story by describing how QCAs can be made into MAJORITY, OR, AND, and INVERTER logic gates.
How Semiconductors and Transistors Work
20 Nov 2005 |
This animation shows how semiconductor crystals work and how they are used to make transistor switches.
Molecular Beam Epitaxy
16 Nov 2005 |
Microelectronic devices are made by repeating two steps: 1) Depositing a thin uniform layer of material; 2) Then using a photographic process to pattern and remove unwanted areas of that layer.
Scanning Electron Microscope
This resource describes a scanning electron microscope (SEM). It includes detailed depictions of how the electron beam is focused and used to create hugely magnified images of experimental specimens.
Scanning Probe Microscope Piezoelectric Crystals
In this resource we disassemble the piezoelectric assembly of a scanning probe microscope. At its core is a white cylinder of the piezoelectric material. If you look closely, it has a granular texture that reflects the fact that it is actually made up of many small crystals.
Scanning Probe Microscope Operation
Scanning Probe Microscopes (SPMs) include Atomic Force Microscopes (AFMs) and Scanning Tunneling Microscopes (STMs or STEMs). They are the only instruments in widespread use that can actually "see" single atoms! You can skim this resource quickly to learn the general concepts of SPMs, or you can...
Fabrication of a MOSFET within a Microprocessor
This resource depicts the step-by-step process by which the transistors of an integrated circuit are made.
What is a Nanometer?
02 Apr 2005 |
Join Laura and Martin on a wild ride through the milliworld and the microworld to reach the nanoworld. Along the way, they discover how small a nanometer truly is.
Nanotechnology is not just a topic for physicists, chemists, and engineers. Laura explains the important role of biologists in this field, and shows how they may help provide clues to molecular assembly techniques.
Scanning Probe Microscopes
15 Mar 2005 |
Laura explains how scanning probe microscopes can be used to create images of small devices, molecules, and even atoms! A large-scale version of the scanning probe microscope is built out of Legos to show the basic principles.
Feasibility of Molecular Manufacturing
14 Mar 2005 |
Martin and Laura have an interesting debate about the feasibility of Molecular Manufacturing. Can molecular assemblers be developed to create new materials, new devices, and even macroscopic objects? Find out... If Martin ever wakes up!
Nanomanufacturing: Top-Down and Bottom-Up
Martin presents an overview of nanomanufacturing techniques, explaining the difference between top-down and bottom-up approaches.
