Students and teachers alike will appreciate the very helpful Dictionary of Units Web Site. As part of the Centre for Innovation in Mathematics Teaching, the site "provides a summary of most of the units of measurement to be found in use around the world today (and a few of historical interest), together with the appropriate conversion factors needed to change them into a 'standard' unit of the...

While the idea of a National Institute of Standards and Technology (NIST) Virtual Museum may make some cast a drowsy eye, they would be quite pleased to learn that the Museum's website contains a host of engaging online exhibits that examine such topics as the standardization of women's clothing, the saccharimeter, and the letter sorting machine. The standardization of women's clothing exhibit is...

This website from the National Institute of Standards and Technology (NIST) provides information on the metric system and useful conversions to know when cooking.

The Capsule History section provides an overview of America's metric history and the slow process of "metrication." Also...

Weights and measures may not be the first thing that most people wake up in the morning thinking about, but such matters are terribly important. The National Institute of Standards and Technology (NIST) has created this site to provide information to concerned stakeholders about the work of their Office of Weights and Measures. The mission of the Office is to promote "uniformity in U.S. weights...

It's certainly not impossible to learn about Newton's laws, momentum and other key principles of physics without multimedia learning activities, but it's a bit more fun to have such resources on hand. With funding from The Australian Learning and Teaching Council, Professor Joe Wolfe of The University of New South Wales has created this rather remarkable set of physics teaching resources. Visitors...
