Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)

This manometer is a modification of a design reported previously. It contains simplifications in the design of the manometer itself and in the associated electrical circuit. The apparatus is useful in the study of gas-phase reaction kinetics. (BB)

The author records her experiment with her daughter from birth to the age of four and a half to determine whether a child in a monolingual environment could grow up speaking two languages. The record traces the child's development in both English and French. (MF)

Describes an exercise which familiarizes students with organic chemistry terms and introduces preferential degradation reactions. (CP)

A colorimetric procedure for the determination of serum iron for use in freshmen and sophomore level quantitative analysis laboratories is described. (CP)

Short reports contributed on a variety of biology topics are presented. (CP)

Short reports contributed on a variety of topics in chemistry are presented. (CP)

A variety of topics in physics are covered by these contributed teaching and laboratory equipment suggestions. (CP)

Associates science teacher "bad days" with the inability to answer the questions asked by students. Proposes that publications focus on providing the answers to recurring questions experienced by science teachers. (CP)

This experiment, mixing solutions of potassium iodide and lead nitrate to give a bright yellow lead iodide precipitate, often leads students into other topics such as making paint from the precipitate. (BB)

Three studies are described in which choice reaction time (RT) was related to such psychometric ability measures as verbal comprehension, numerical reasoning, hidden figures, and progressive matrices tests. Fairly consistent negative correlations were found between these tests and choice RT when high school samples were used. (Author/CTM)

Describes benefits and techniques for utilizing Mormoniella vitripennis (jewel wasps) in teaching biology. Feeding, courtship, egg-laying, and insect behavior investigations are presented. (SL)

Provides a variety of science activities structured around the germination and growth of oak trees from acorns. (CP)

Two experiments explored the question of when people will respond to negative labels by confirming them and when they will respond by disconfirming them. (Editor)

Presents four science experiments for the junior high level relating to electric switches, a chemical card game, combustion energy, and chromatography. (SL)
