| Summary |
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Each concept is illustrated with a variety of excellent experiments, explanatory captions, artwork, and computer animation to illuminate what is happening both visibly and at the molecular level. Thought stimulating questions are interspersed. The experiments are too difficult or dangerous to be conducted in a school lab. The experiments demonstrate the processes of scientific reasoning and the nature of scientific evidence.Today: Current, voltage and resistance are all related. This relationship is explored qualitatively and quantitatively through practical investigation. Graphics help explain the observed phenomena.Segment (a) Current and potential difference - defining and measuring current and voltage in a series and parallel circuits.Segment (b) Ohm's law - the quantitative relationship between resistance, current and voltage.Segment (c) Resistors - investigating total resistance for resistors in series and parallel |
