Potash, an essential raw material of the 18th century, used to be produced from the ashes of plants. Known since antiquity, it was in 1807 that Humphry Davy put an end to the decades-long controversy about its nature as a compound. The technology behind potash production was implemented in Brazil by the Portuguese naturalist Frei Velloso. The…

It is certainly widely appreciated that there is much to be gained in the fertile crosstalk between science and history--whether bringing a historical perspective into the science classroom (Wieder, 2006) or a scientific perspective to the study of history (McElvaine, 2002; Smail, 2008). Perhaps the major impetus for using history in teaching…

Describes a college course that provides a challenging learning experience in science based upon famous experiments and observations dating from the time of Aristotle to the present day. Presents information concerning (1) the course organization, structure, laboratory development, and expectations; (2) course content by quarter; (3) evaluation of…

Explains how Darwin's observations and experiments can be used to show the true nature of science and good scientific methods. (PR)

Describes experiments by Thomas A. Knight on geotropism. These experiments took place about 200 years ago and used a centrifuge. (PR)

This document series has been established as part of Unesco's Science and Technology Programme to encourage an international exchange of ideas and information in science education.

Presents a course outline for the study of biotechnology at the high school or college level. The outline includes definitions, a history, and the vocabulary of biotechnology. Presents a science experiment to analyze the effects of restriction enzymes on DNA. (MDH)

Identifies the development of practical and investigative skills featured in science qualifications at all levels (foundation, intermediate, and advanced) and all types (general, general vocational, and occupationally specific). Reviews the debate over the purpose of practical experimental work in science education and training. (Author/CCM)
