Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Proposes that the psychological problem of students expecting a particular result in an organic chemistry laboratory and, therefore, working in an unthinking manner be attacked by assigning experiments that give students unexpected results. Gives four examples of such experiments with strategies for teaching them. (CW)

Advocated is the use of interactive centers to supplement existing classroom laboratory experiences. Activities found in the center and modified classroom versions are described. The problems that arise when primary students meet sophisticated exhibits is discussed. (KR)
