Ocean water is salty and, in general, cold. Differences in the water density associated with temperature and salinity are vital in shaping the Great Ocean Conveyor. This lesson plan demonstrates how salinity and temperature affect density of water.

Just as air can have different densities, water can have different densities as well. As the salinity of water increases, the density increases as well. Fresh eggs will float in saltwater, but will sink in freshwater. This will show that as the salinity increases the density also increases.

What does up, must come down. Precipitation is the most commonly seen aspect of the hydrologic cycle. Students will learn how the water cycle works using 3-D paper craft activity. The students will see a demonstration of the concept of precipitation.

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...
