Exploring the Nanoworld: A Presenter's Guide

 

This presentation is a product of the University of Wisconsin Institute for Chemical Education. Included in your kit is a presentation manual with directions. For further information, please check here.

 

 

 

This presentation will guide you through four fun and simple activities to help introduce the world of Nanotechnology to your class! The manual also provides supplemental information for each activity.

 

 

Memory Metal Activity

 

 

Take a piece of memory metal and bend it.

 

Dip the metal into a cup of hot water.

 

Pull the metal out. What do you notice?

 

What's going on? Order to find out!

 

Light-Emitting Diodes (LED) and Fiber Optic Activity

 

Turn on your LED and hold it at one end of the fiber optic, gently bending the fiber. Can you see light glowing at the other end?

 

What's going on? Order to find out!

 

Diffraction Activity

Hold the diffraction slide up to your eye and the LED at arms length. Shine the LED into the diffraction slide. What patterns do you see?

Seeing Atoms Activity

 

Pull the probe strip free from the magnet. Flip the magnet over and drag the probe strip across it. What do you notice?

 

Now try dragging the probe strip down the magnet. Is it more or less difficult?
