Reviews software packages used in microcomputer-based laboratory (MBL) experiments. They include programs for a precision timer, frequency meter, heat and light experiments, sound experiments, spectrum analysis, biofeedback analysis, and others. Reviews include a brief description, source, current cost, and equipment requirements. (JN)

Describes a fourth-grade unit on density which introduces a concept useful in the study of chemistry and procedures appropriate to the chemistry laboratory. The hands-on activities, which use simple equipment and household substances, are at the level of thinking Piaget describes as concrete operational. (BC)

Lists 25 energy activities and describes two experiments (materials needed and procedures used included) for secondary/middle school students. Like activities for younger children listed in part 1 (appearing in Vol. 65, No. 229), these activities are designed to provide concrete experiences for teaching various aspects of the energy concept. (JM)

Describes simple, electrical projects with dry cell batteries and lamps designed to teach children about conductors, insulators, and switches. Instructions for construction of circuits, the science ideas in each project, and suggestions for extending each of the investigations are included. (JM)

Describes the characteristics, care, feeding, housing, and diet of garter snakes. Includes tips on using the snakes for short-term classroom projects and brief comments on handling snakes. (JN)

Presents an activity for grades three through six on the life/death of icebergs, their characteristics and effects (includes materials needed and procedures). Also presents an high school activity on marine careers which includes background information and instructions for completing a research paper on an ocean career. (JN)

Proposes the study of edible wild plants as a means of developing an attitude of environmental responsibility in students. Senior citizens can provide considerable assistance for such a program. (SL)

Outlined is a two week unit on weather offered as independent study for sixth- and seventh-year students in Vancouver, Canada, schools. Included is a section on weather lore and a chart of weather symbols. (SL)

Described is a learning activity which utilizes cross age teaching of science topics related to weather. Included are descriptions of seven weather learning center proposals. (SL)

Presented are four how-to-do-it projects including: an environmental education museum, developing chick embryos in plastic bags, construction of an arthropod holding device, and safety planning for beach field trips. (SL)

Several career education activities for science students are listed. Included are questions for interviews and projects in the following areas: plumbing and electricity, environmental control, medicine, wood and wood products, and audiovisual production. (CS)

Described is a set of twelve single concept films produced by the three Skylab crews demonstrating zero gravity science. Each film includes instructional notes. (SL)

The National Aeronautics and Space Administration (NASA) has produced a distance learning series of four 60-minute video programs with an accompanying Web site and companion teacher guide. This teacher guide accompanies the third video in the series. The story line of each program involves six ethnically diverse, inquisitive schoolchildren who…
