Provides basic information on the anatomy, physiology, behaviors, and distribution patterns of the box turtle. Offers suggestions for the turtle's care and maintenance in a classroom environment. (ML)

Background information, procedures used, and typical results obtained are provided for an experiment in which students prepare and study the characteristics of a "slime." A list of general, inorganic, and polymer chemistry concepts fostered in the experiment is included. (JN)

Discusses materials needed, procedures used, and typical results obtained for an experiment involving a dry attack of ores with pyrosulfate flux. The experiment has been carried out by about 150 students a year with a demonstrator-to-student ratio of about 1:15 with no serious accidents. (JN)

Books that may help children appreciate and understand feats that can be performed because of scientific and technological discoveries are discussed. (DF)

To demonstrate negative feedback a power amplifier is constructed from an operational amplifier together with a complementary pair of transistors as an output stage. The amplifier is developed and tested stage by stage, and at each stage the defects apparent at the previous stage are eliminated. (JN)

The author discusses ways of revising presientific ideas among children, using the topic "Changes in Aggregate States of Matter" as a source for specific examples. (JH)

The number of flies that crawl through a small hole from one chamber to another is used to demonstrate principles of chemical kinetics. (CP)

The author describes a special experiment making peanut brittle and amusing activities based on chemical nomenclature used as motivational tools. (CP)

A baby-food jar is the constant in this group of ten basic science experiments. (Editor)

The product test and an experimental approach to the guise of matter, constitutes one approach in learning about materials. (Editor)
