Presents development and preliminary results of a research project evaluating a curriculum guide developed by the National Association for the Advancement of Humane Education. Activities included humane education along with concepts and skills in language arts, social studies, science, and mathematics. Results are mixed with more impact on early…

Gives guidelines for creating activities to teach classification skills using such holiday materials as nuts, pine cones, evergreen branches, hard candy, and package stickers. Provides ideas to share with parents in developing skills at home, and precautions in selecting objects. Encourages emphasis on similarities as well as differences when…

Describes a demonstration in which the pattern on a rotating turntable can be affected by humming and adjusting the pitch of the hum. At some frequency, if conditions are right, the pattern can be stopped, or "strobed." Also describes a way to introduce humor into physics instruction. (JN)

Several activities focusing on the elasticity of rubber bands and chalk are described. Explanations for the observations noted are included. (JN)

Describes a series of experiments which use a modified automobile alternator as a portable source of three-phase alternating current. The low frequency capabilities of this source allow the phase relationships to be demonstrated using an ordinary galvanometer. (GS)

Three activities for involving students in projects that incorporate writing, drawing and recording their findings are included. The discovery approach is emphasized. (EB)

Describes the use of magnets to simulate s, p, and d atomic orbitals from which a wide variety of molecular orbitals can be derived. The technique gives students an idea of molecular orbitals' shapes and stresses the importance of symmetry labels. (MLH)

Described is a method of rearing common house flies in a biology laboratory. Included are 16 suggested biological investigations utilizing the house-fly. (SL)

Described is a method of introducing children to the study of star constellations. A detailed sample lesson is included. (SL)

Presents the results of a survey of English physics teachers concerning the percent of classroom time they spend in practical work, the objectives of practical work, and their use of student projects. (MLH)

Describes nine biology experiments, including osmosis, genetics; oxygen content of blood, enzymes in bean seedlings, preparation of bird skins, vascularization in bean seedlings, a game called "sequences" (applied to review situations), crossword puzzle for human respiration, and physiology of the woodlouse. (CS)

Contains information regarding pollen and human allergies. Lists most common types of pollen, describes pollen morphology, diagrams and apparatus for collecting pollen, and suggests laboratory activities such as pollen counts, pollen concentration, dispersal, and meteorological effects. (CS)
