Learn about units of temperature and other interesting facts.

A very simple electrical resistance thermometer is described that can be built, calibrated and tested in a school laboratory at virtually no cost. With it, flames, focused sunlight and other high temperature sources can be probed. The...

Find out how scientists measure the air temperature to accurately report the weather.

Instructions for how to make an electrical thermometer. The electrical thermometer works like this - the design consists of four resistors each made from about 40 meters of very thin copper wire. The electrical resistance of wire changes...

Read about the use of data loggers in one high school class. The data loggers were the key to quantifying the relationship between temperature, light, and biodiversity. Although this is relevant to high school science links are provided...

Learn about the life and work of Anders Celsius, the Swedish astronomer who proposed the Celsius temperature scale which bears his name.

We see numbers everywhere around us - measuring the temperature, counting money, telling the time, etc. The numbers that are used for counting objects are called "natural numbers". This article explains the properties of natural numbers...

In simple terms, density is the mass of anything - including air - divided by the volume it occupies. In the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air's density depends...
