Scholars Online Summer Course

I propose to bring before you, in the course of these lectures, the Chemical History of a Candle. There is no better, there is no more open door by which you can enter into the study of natural philosophy than by considering the physical phenomena of a candle. There is not a law under which any part of this universe is governed which does not come into play, and is not touched upon, in these phenomena.

— from the first of six lectures by Michael Faraday,
delivered in 1861 as the Royal Institution's Christmas Course of Lectures Adapted to a Juvenile Auditory.

Michael Faraday (1791-1867) was one of the greatest experimental scientists the world has ever seen. His discoveries and inventions include the concept of the electric field, the electric motor, the electric generator, laws governing magnetic induction of electrical current, isolation of a number of chemical compounds, and proof that magnetic forces bend polarized light.

Childless himself, Faraday loved teaching children, and inaugurated a series of lectures for children at the Royal Institute in 1825. The lecturer performed experiments live on stage, and the first six rows of the Institute's Lecture Hall, usually occupied by prestigious Fellows of the Royal Society, could on these occasions only hold seat visitors under 14 years of age. Between 1825 and his death in 1861, Faraday delivered nineteen of the lecture series himself, introducing the latest concepts of chemistry, electricity, the properties of metals, and forces of nature to his "juvenile auditory". In the process, he revolutionized how science was taught to children. The Royal Insitute has sponsored the lectures continuously since 1825, the only exception being the years from 1939-1942, when London was under attack. Recent lectures have been given by such notable scientists as David Attenborough and Carl Sagan. Faraday's methods also inspired such television presentations as Mr. Wizard and Bill Nye, the Science Guy.

Our eight week course uses the six lectures Faraday delivered on the chemistry of a burning candle in 1860. We are lucky to have the exact text of the lectures, since an enterprising newpaper reporter took them down verbatim in shorthand. We will use these lectures as a starting point — as Faraday did — to discuss to scientific thinking and experimentation, chemical composition of wax, combustion reactions, forces and energy, and the history of the human scientific endeavor. Students will perform adaptations of Faraday's experiments to develop proper experimental techniques (with an emphasis on lab safety) then submit their lab reports for teacher and peer review, and discuss their experiences in online class sessions.


Because Scholars Online personnel cannot oversee the experiments, parents must sign an agreement to provide adequate supervision during performance of experiments.
