Presents the results of an experiment designed to test two hypotheses: (1) a delay of two weeks at room temperature will have no effect on the viability of fertile chicken eggs and (2) refrigeration will have no effect on the viability of fertile chicken eggs. Experimenters were the author and two ninth-grade students. (PEB)

Provides basic information on the anatomy, physiology, behaviors, and distribution patterns of the box turtle. Offers suggestions for the turtle's care and maintenance in a classroom environment. (ML)

Presents directions for an activity designed to illustrate the function of plant nutrients. (PEB)

Describes fecal pellet identification as a technique for animal population surveys. (CP)

Students conducted an experiment to study the plant growth of three Amaryllis plants. Students examined the speed and amount of growth, cross-pollinated the plants to produce seeds, and compared the growth of amaryllis seeds to the growth of onion seeds, a plant in the same family, Amaryllidaceae. (MDH)

Explains a way to determine the age of a turtle, how to care for them and what to feed them while in temporary captivity. (GA)

Describes the life cycle of the Amaryllis plant from bulb to blossom. Suggests 12 activities in which students monitor plant growth, examine plant parts, make drawings of the plant, and eat flowers of other plants. (MDH)

Presents a cooperative activity between home and school in which parents and students examine the growth of a variety of bulbs. Bulbs are taken home to sprout and returned to school to monitor their growth. Students gather data, hone observation and graphing skills, and communicate with their parents on the project. (MDH)

Describes a primarily volunteer project that was developed with private industry to contribute to the research on space-grown vegetables and to promote science as a career. Focuses on the effects of microgravity and space travel on the germination and growth of plants. (DDR)

Describes using picture books and science activities in early childhood science instruction. Suggests titles of books and activities for the following topics: Time for Pets; Environmental Awareness; Dinosaurs Galore; Nighttime Science; Simple Machines; Insect Collections; Snowy Days; Water, Water, Everywhere; and Experimental Activities.
