A discussion of the historical background of man's use of seeds is followed by an explanation of some of the basic concepts relating to seeds. Collecting seeds is discussed, and eight classroom activities are described. (DT)

Describes and details the construction of a land-water environment using an aquarium and variety of terrestrial and aquatic materials and organisms. Suggests activities such as identification of organisms, observation of predator-prey interactions, construction of food webs, and recognition of interdependence of biotic and abiotic factors. (CS)

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)

Presents a mini-environment project as a valuable teaching tool for presenting ecology. The procedures for setting up a mini-desert in the classroom are presented as a model. Basic components of the mini-environment project are also included. (HM)

Describes a project in which students study plant life and the relationship of plants to one another in a meter quadrant. Information to be collected is edaphic data which is then graphed and interpretations made. (BR)

Describes a game for grades three-six designed to demonstrate the interdependence between living things and the physical factors of their environment. Although instructions (including preparing game cards) are provided related to a pond, the game adapts to other environments such as a field, woodland, or desert. (Author/JN)

Provides an OEAGLS (Oceanic Education Activities for Great Lakes Schools) activity showing how biological sampling can be taught using acquatic examples in a "dry lab." The activity, requiring use of mathematical/observational skills, simulates a plankton sample and stimulates discussions of how environmental/human factors can cause…

Describes two lessons on ecology for elementary students developed by four ecology students at the University of Georgia. (SL)

Six paper and pencil activities on marine ecology are presented with answers. Included are a food pyramid, a maze, a find-a-word puzzle, a sea food chain, a crossword puzzle, and a predator-prey puzzle. (CW)

Describes interdisciplinary activities for teaching elementary science using eggs. Each activity is designed to introduce larger thematic units. Activities include making egg animals (study of animal survival), throwing raw eggs at taut vertical sheets and making cars for egg passengers (force and momentum), and making eggshell domes (dome…
