It is useful to know the approximate sizes of things. Is something bigger than a bread box? Will it fit through a doorway? Is it as big as it is supposed to be? These are all questions that we may find ourselves asking on a regular basis. The way people have measured things has varied over time. For example, in Egyptian times, the length of an obje...
Inclusive teaching refers to methods that are designed to engage students in learning that is meaningful, relevant, and accessible to all. Creating an inclusive environment is a continuing process that begins before the class starts and is built into the class design. For more resources, go to our Inclusive Teaching Practices page. Strategies for t...
In everyday life the English system of measurement with units like feet, gallons and pounds is primarily used in the United States. Scientists and the rest of the world use the metric system of measurement with base units such as the meter, liter and gram. The base unit is then multiplied or divided by powers of ten to represent larger or smaller m...
In order to give students and teachers a more hands-on sense of scale, we developed a free, 3D touchscreen app called AtomTouch. AtomTouch includes a size and scale introductory video, and many engaging and educational activities to give students a real sense of atomic behavior.

Here are some other everyday objects measured in nanometers: One inch equals 25.4 million nanometers. A sheet of paper is about 100,000 nanometers thick. A human hair measures roughly 50,000 to 100,000 nanometers in diameter. Your fingernails grow one nanometer every second.

To many scientists, things are at the nanoscale if they are so small that they display different properties to the large scale material. This mostly happens when particles are only a few nanometres across. For example, you may know that water boils at 100ºC (at a pressure of 1 atmosphere), but that is only true for large amounts of water.
