We feel the wind everyday. The air is almost always in motion. One day it may be from the north and the next day from the south. There are many sources for wind: mechanical sources such as fans and, in nature, falling rain as it drags air along. But what is the origin of wind on the earth? Using a...

We all know the oceans are salty but so are other sources of water. The oceans have a salinity (salt content) of 35%. The Dead Sea has an average salinity of 290%, almost nine times saltier than the oceans. But what actually does that mean? Just how salty tasting are these various bodies of water?...

Barometers using mercury are heavy and fragile. The first working version of an aneroid (without water) barometer was built in 1843 by French scientist Lucien Vidie. This made the barometer very portable and it became a commonly used meteorological instrument. It was still calibrated to the...

The amount of air over us is constantly changing. As a result, the weight of that air, called pressure, is constantly changing. These changes in air pressure are indications of changes in our weather. We measure this change using a device called a barometer (bar-meter or measurer).

Pressure is not only a matter of altitude but also dependent upon the temperature. As the temperature increases so does the pressure. The molecules and atoms that comprise the air we breathe gain energy as they absorb heat. That increase in energy results in faster moving atoms which we observe as...

Bernoulli's principle states that in fluid flow, an increase in velocity occurs simultaneously with decrease in pressure. The students will discover that the faster air moves (air acting as a fluid), the lower the pressure beccomes within that air flow. They will see this effect blowing between two...
