Troy Dassler's 12 minute TEDx presentation about how he came to introduce nanoscience into his elementary school. Based on his experiences at Aldo Leopold Elementary School working with scientists at the University of Wisconsin MRSEC.
Students will examine the order of size of objects from the nanoscale to macroscale to visualize exponents and decimals, make size comparisons of objects, and develop an understanding of how small a nanometer is in comparison to common objects. This lesson uses the metric system.
There are two activities in this lesson, the Fly Prison and the Water Maze. The Fly Prison is a hands-on modeling activity designed to introduce students to the area of nanotechnology and give them a basic understanding of how researchers build very small devices by the self-assembly of molecules. The water maze is a follow-up activity to give the students a chance to practice and demonstrate what they have learned.

This activity developed by NNIN explores how nanotechnology can be used to change the properties of a copper surface so that it either attracts or repels water. It is appropriate for middle school and high school students.
After an introductory PowerPoint on nanotechnology students are given a chance in groups to explore consumer products through an information sheet provided over available consumer products. After learning about products students can create a presentation for a particular product; test their product; or research a career in nanotechnology.
A focus of the National Science Standards is that students are provided opportunities to read and analyze science outside of their textbooks. This lesson will allow reading across the curriculum by providing students the opportunity to read about nanotechnology. In addition this will open up an opportunity to engage students in discourse about a significant technology that will allow them to analyze and reflect on its implications and significance for the future.
This lab is designed to help students understand how nanoparticles may be more effective catalysts by investigating how the surface area-to-volume ratio of a substance is affected as its shape changes. This lab is meant to complement a chemistry unit on catalysts. Nanosized materials have a significant portion of their atoms on the surface. Understanding how catalysts work involves studying chemical reactions at the molecular and atomic scale. For this reason, catalysis can be considered one of the earliest forms of nanoscale science.
This is a series of four lessons which build upon each other to explore the use of nanotechnology in cosmetics as well as the social and ethical issues associated with nano-based cosmetics. The purpose of these lessons is to familiarize students with the chemistry of cosmetics and the anatomy of the skin.
Ferrofluid is a unique material that has both magnetic and liquid properties. It is a colloidal solution of nano-sized particle of magnetite suspended in a liquid. (Purchased). This activity will review what students know about magnetism and compares that knowledge to how ferrofluid behaves.
