Surveys the mounting damage occurring throughout the world by acid precipitation to lakes, forests and buildings. Discusses acid rain’s effect on human health. Illustrates some efforts of science, industry...
Precipitation theory, use of the balance, washing and filtering precipitates etc. Older types of equipment used.
Support video for course S271. [For synopsis of SPECIAL RELATIVITY, see separate programme entry.)
Demonstratess how weather is influenced by temperature, air movement and precipitation. Looks at each of these factors and illustrates how they can be measured, how predictions can be made, and what the...
Describes some of the physical mechanisms responsible for electrostatic charging of a thundercloud and the subsequent precipitation and electrical discharges resulting in lightning. The role of pointed...
Explains how the weather works, to help interpret official forecasts more accurately and read between the lines to turn a large area forecast into a local one. Covers energy transfer, gas law, adiabatic...
Shows the process of isolating high molecular weight genomic DNA from bacteria. This involves lysis of bacterial cells, dialysis, alcohol precipitation, and spooling DNA onto a glass rod. Then DNA is...
Methods of observing the weather. Difficulties of obtaining an adequate data coverage of the globe by means of conventional surface and upper-air observations are pointed out. Possibilities of using balloons...
The need often arises to quickly isolate plasmid DNA transformed within bacteria away from genomic DNA and other cellular components. The procedure of lysing the bacteria, documented in the video, is called...
