Abstract
A solution conductivity apparatus is described that can be used to measure the relative conductivity of various solutions. The apparatus can be used as either a hand-held model employing a 10-element LED display or a lecture-hall demonstration model employing a 10-incandescent-lamp array.

Ed Vitz and Melissa KistlerJournal of Chemical Education2004 81 (1), 63A conductivity demonstration device is described which operates on 12V and yet will illuminate a bulb brightly enough for use in a lecture hall, even when used with solutions of low conductivity.
Is Every Transparent Liquid Water?
Muhamad Hugerat and Sobhi BasheerJournal of Chemical Education2001 78 (8), 1041Is Every Transparent Liquid Water?
Muhamad Hugerat and Sobhi BasheerJournal of Chemical Education2001 78 (8), 1041The accepted description for water in schools worldwide is a transparent and colorless liquid. Since students in lower grades (ages 8-13) often see warning signs "Do not drink this liquid--it is not water", we believe that presenting experiments that ...
