August 15‚ 2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists

to a garden (let alone the beach) their streets are full of cars; school playgrounds are usually flat‚ sterile areas of concrete which offer no interest or little opportunity for interaction.” The consequences of this according to his theory of Compound Flexibility is that children who have little control over the world inevitably have fewer positive experiences‚ which in turn slows the development of their self confidence. Loose-parts theory has also been referred to by Bob Hughes in his elucidation

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

There are different types of Compound Interest. Interest is the amount of money earned in a saving account. * Simple Interest: Interest calculated once on the principal. * Compound Interest: Interest calculated for a given segment of time of the investment. For example‚ compounded monthly‚ means the interest is calculated each month and combined with the principal. So‚ for the next month‚ interest is earned on the interest. Continuously Compound Interest Formula P: ending
