Congenital hyperinsulinism (HI) is a genetic disorder in which the insulin cells of the pancreas, called beta cells, secrete too much insulin. Excess insulin causes low blood sugar (hypoglycemia). Ordinarily, beta cells secrete just enough insulin to keep the blood sugar in the normal range.
Conduction Insulators, conductors, semiconductors, and superconductors Every material in the world can be defined in terms of how well it conducts electricity. Certain things, such as cold glass, never conduct electricity. They're known as insulators.Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.Last, are materials called superconductors, which when brought down to very low temperatures turn into superhighways of current -- they conduct electricity without any resistance whatsoever.hey're known as insulators. Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.
Some substances when dissolvedin water to produce a solution will conduct an electrical current. Such substances produce ions when dissolved in water, and it is the ions which carry the current through the solution.The research aspect of this science fair project is to use a conductivity device to determine if various substance dissolved in water can or cannot conduct electricity.his science fair project focuses on the use a conductivity device that will enable the investigator to determine if a substance dissolved in water can or cannot conduct electricity and if it can, what type of conductor (electrolyte) it is.
