Pbs: Nova: Making Stuff: Stronger

The first in a four-part PBS series, hour-long video defines "strength" of materials, with examples ranging from steel cables to mollusk shells. Insight from research and experts offers a look into the process of "re-engineering" nature's materials "to create the next generation of strong stuff." Other videos in the Making Stuff series focus on making materials smaller, cleaner, and smarter. Includes an activity guide with customizable handouts, PowerPoint presentations, demonstrations, and a toolkit.
