Describes an undergraduate physical chemistry experiment which demonstrates the principles of solution calorimetry and the entropy titration technique. (CS)

Science activities for the visually impaired (SAVI) introduces blind and visually impaired children (9 to 12 years old) to physical and life sciences in a multisensory way. Evolution of SAVI activities involves exploration, local trials, and national trials. SAVI project materials can help integrate handicapped children into the mainstream through…

Presents three problems that can be used in classroom to motivate chemical engineering students at the college level. (HM)

Describes a computer program which enables sixth-form (16 to 18 year-olds) British students to investigate the amino acid sequence of any chosen small oligopeptide. (HM)

Describes a learning project in analytical chemistry in which students are required to select instruments from the manufacturers' literature that would be suitable for a given analytical problem. Several examples are given. (SA)

Seven steps are given for identifying a rock or a mineral. (SA)

Describes a simple demonstration that illustrates the nature of isotropic substances by tearing newsprint, magazines, and wrapping paper. (BT)

Presented are two problem exercises involving rapid compression and expansion of ideal gases which illustrate the first and second laws of thermodynamics. The first problem involves the conversion of gravitational energy into heat through mechanical work. The second involves the mutual interaction of two gases through an adiabatic piston. (BT)

Discusses how biology teachers can design or adapt existing laboratory and field experiences to promote reflective thinking and self-regulation of students. (HM)

Presents examples of creative humor activities produced by gifted elementary students. These include droodles, create-a-creature, wanted posters, and work machines. (MA)

Provides suggestions for preparing, maintaining, and using a beehive. Includes addresses of bee supply companies and blueprints for constructing a hive. (MA)

Presents an activity whereby students describe the path of Mars through a background starfield. Includes purpose, materials, pre-lab, and procedure. Also provides guidelines for making a dial-a-planet wheel. (MA)

Describes independent and group research activities for the classroom focusing on the properties of air. (SS)

Gives an explanation to the process of charging the conventional leaf electroscope, by induction, using a charged insulated rod. (GA)

A new, small magnetic susceptibility system is described which can be constructed from commercially available components for less than one hundred dollars for use with a standard laboratory balance. (BB)
