Exploring the Nanoworld Teaching Modules

helps teachers incorporate nanotechnology into high school chemistry and middle school technology classes. High school modules explore x-ray diffraction and scanning probe microscopy, shape-memory alloys, light emitting diodes, and ferrofluid. Middle school modules examine magnetism, memory metals, and "How we can 'see' what we cannot see." Modules include overviews, curriculum suggestions, lesson plans, guided notes, experiments, and assessments. (University of Wisconsin-Madison, National Science Foundation)

Interesting Fact:

Nickel-titanium shape memory alloy, or Nitinol, was discovered in 1965. Nitinol is an acronym for Nickel Titanium Naval Ordnance Laboratory, where the alloy's remarkable properties were discovered. Nitinol is an alloy containing nearly equal numbers of nickel and titanium atoms, leading to its common compositional representation as NiTi.
