Discoverer/Developer
Gilbert Lewis (1875-1946) was born in Weymouth, Massachusetts. At the age of 14, Lewis started college at the University of Nebraska. After getting his PhD at Harvard, he taught at MIT. He eventually became a professor at the University of California, Berkeley. Lewis became part of the National Science Academy in 1913. He did work on relativity and light and matter interactions that complimented Einstein's work on the subject. His student Harold Urey received the Nobel Prize in Chemistry for discovering deuterium. In 1916, he published a paper on the covalent bond, and in 1923 he published his theory on acids and bases. The idea of giving students problem sets from which to practice and learn chemistry was largely due to Lewis and his teaching philosophy. Lewis was nominated for the Nobel Prize 35 times, but never received it. Found dead on the floor of his laboratory in Berkely, there is debate as to whether Lewis's death might have been a suicide.

Classroom Demonstations
Investigate lab procedures suitable for live classroom demonstrations or guided student exploration.
Students requiring adaptations to gain the full benefit of a demonstration may find a worksheet with guided observations useful. Alternatively, a teacher may wish to use a worksheet with guided observations to model what observations all students should be making during a demonstration.
