Procedures for using soap films to determine the shortest series of lines connecting several points. (CP)

Describes a variation of "the suffocating candle" activity used to develop the process of predicting based on reliable data. Instead of using jars of varying sizes under which the burning time of candles is measured, the same jar is used while the candle is elevated on varying numbers of blocks. (CS)

Lists materials and procedures for experimenting with detergents. Included are methods for determination of the densities of dry detergents, ph values of detergent solutions, and a discussion of the ability of detergents to remove iodine stains from cloth. (CS)

Describes a paper chromatography experiment designed for fifth and sixth grade students. Utilizes common materials that need no special ordering. Background information, conclusion questions, and sample chart are included. (MA)

Using winter snow, kindergarten students can explore the properties of water. Students demonstrate melting, freezing, expansion, and evaporation through a number of activities involving a paper cup and a scoop of snow. Procedures and student reactions are described in detail by the teacher-author. (MA)

Activities and experiments with leaves are given for use with elementary students. Classifying and measuring are ideas which are suggested for involving children in some in-depth projects with leaves. (SA)
