Describes a science activity in which sixth-grade students, using tookpicks and spherical breakfast cereals to construct molecular models, discovered that compounds with the same molecular formulas can have different structural formulas and therefore different physical properties (isomerism). (JR)

An activity involving future elementary school teachers designed around inexpensive balloons which when launched contained postcards to determine the geographic location of the landing. The investigation is student-centered, involving unknown questions, and was conducted for enjoyment. (DF)

SCIS materials are modified for use with acoustically handicapped pupils. (CP)

Discusses activities related to the Elementary Science Study (ESS) unit "Growing Seeds." The unit teaches students to manipulate, observe, and record the growth of seeds. Activities foster classifying, hypothesizing, and predicting skills. Enrichment activities and a culminating activity for the unit are suggested. (JN)

Provides rationale for and description of an acid rain game (designed for two players), a problem-solving model for elementary students. Although complete instructions are provided, including a copy of the game board, the game is also available for Apple II microcomputers. Information for the computer program is available from the author.…

Describes an inquiry procedure to determine whether soft drinks are pressure or vacuum packed and then utilizes the "pop" theme for several other science activities. (LS)

Demonstrates how students can build a plankton net using common materials for environmental education. (LS)

Intended to aid teachers help students discover the concept of human beings interrelating and interdependent with their environment. A science activity used with sixth grade students involved in a functional recycling system for newspapers is described. The program grew into a community-wide project, incorporated with city council. (EB)

Describes the procedures in growing thymol crystals and suggests eight activities which can be carried out by students in examining crystals. (BR)

Describes construction of a pinhole camera with simple materials and five experiments to be conducted, as well as instructions in creating a working camera obscura. (BR)

The article outlines an activity for providing a hands-on opportunity for elementary and middle school science students to study the theory of the earth's crustal change over the past several hundred million years. The theory of continents drifting away from one super continent is presented with the supportive evidence that scientists have…

A seventh-grade botany project involving experiments with beans is described. (DT)
