LIGHTNING ROD American statesman and inventor Benjamin Franklin was particularly interested in electricity and set up a small laboratory in his house to investigate its properties. His interest soon switched from electricity to lightning after he noticed the similarities between the two. One stormy night, he conducted a life-threatening experiment to demonstrate that lightning is the result of an electric build up. He constructed a kite that carried a metal spike and flew it into the thunderstorm. The kite had a key attached near the bottom of the ribbon and Franklin noticed that it sparked as he brought his knuckles close to it. Franklin had shown that lightning was form of electricity and he went on to use this knowledge to design a lightning rod to protect buildings.
LINNAEAN TAXONOMY Linnaean taxonomy is a system of classification of living organism that is used throughout biological sciences. The most important feature of Linnaean Taxonomy is a system known as binomial nomenclature. The first name identifies the genus to which the organism belongs; the second name is its unique species.
BIMETTALIC STRIP
A bimetallic strip is a simple device which converts thermal energy into mechanical motion. It is used as a thermally activated switch or heat indicator and works on the principle of differential expansion of heated dissimilar metals. The bimetallic strip is made up of two different metals which are bonded together to form a straight, flat strip or a concentric coil. When the strip is heated, one of the metals heats up and expands faster than the other, causing the strip to bend. This mechanical deflection is then harnessed in various ways to switch electrical circuits or move a dial to a give heat value indication.
