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.
The purpose of this lesson is to familiarize students with size, scale, and measurement by exploring size and scale through a variety of activities. In part 2, students explore size effects in chemical reactions.
Selection of clean room videos providing an introduction to the special kinds of tools and equipment used to do nanoscale research.
Australian animated videos on nanoscience scale (Part 1) and properties (Part 2). Underpinning an understanding of nanotechnology are two foundational aspects. First appreciating the nanoscale - how might we imagine one billionth of a meter? And second exploring novel nano properties such as conductivity, color and reactivity. This pair of animations explores both scale and properties.
Narrated by Stephen Fry, this film explores the strange world of nanoscience. www.nanoyou.eu Produced with the assistance of Nanoscience Centre, University of Cambridge Produced and DIrected by Tom Mustill Narrated by Stephen Fry
This interactive animation is a modern version of the classic powers of ten video. It takes you all the way from the (estimated) outer reaches of the universe down to the length of a Planck. Somewhere in the middle, the animation let's you explore the nano-scale. Click on different objects as they zoom by to learn more.
In this segment of Material Marvels, Dr. Ainissa Ramirez demonstrates how materials behave strangely when they are nanosize—about 1/100,000 the thickness of your hair.
"Exploring Size - Ball Sorter" is a hands-on activity in which visitors use sieves with different-sized holes, to sort balls by size. They learn that researchers are developing new technologies that can sort nano-sized things, including filters with nano-sized holes.
"NanoSense Activities" has 4 curriculum units to help high school teachers and students understand nanoscale science. Each unit includes background materials, directions and instructional materials. Units include: Size Matters - Introduction to Nanoscience, Clear Sunscreen - How Light Interacts with Matter, Clean Energy - Converting Light into Electricity, and Fine Filters - Filtering Solutions for Clean Water
A formative evaluation was conducted on Three Drops, an Immersive Digital Interactive (IDI), that allows visitors to interact with simulations of water at different size scales where different physical forces dominate. This evaluation revisits the exhibit after changes were made to address issues identified in the first series of formatives.
