Illustrated and described is a convection box for classroom use to stimulate concept development in elementary school children. Other equipment and apparatus that may be used in open-ended science activites are listed. (CS)

Lists experiments and activities that will aid the young child in understanding the relationship between the position of a body in space and the directions of the force of gravity. (CS)

Describes exploratory activities for a young child seeking to become acquainted with the world in which he lives. (EB)

First of a series showing ways in which the preschool setting can provide exploratory activities for the young child seeking to become acquainted with the world about him. Suggests ways to present the concepts of climate, clean air, personal space, and noise level. (EB)

Children in grades two and five explained such weather phenomena as wind, clouds, thunder, lightning, rain, snow, and rainbows during interviews. Results indicate that most students in both grades were at a stage of nonreligious finalism and do not use true causality in explanations. Implications for teaching are discussed. (DH)

Presents thirteen concepts about water and suggests science activities for each. Designed as early childhood learning experiences. (MA)

An account of a teacher's experience in presenting astronomy to 12 to 15 year olds in a summer science program is presented. Observations of planets, meteors, and the sun are the major projects which are discussed. (SA)

Provides suggestions for note-taking from books, lectures, visual presentations, and laboratory experiments to enhance student knowledge, memory, and length of attention span during instruction. Describes topical and structural outlines, visual mapping, charting, three-column note-taking, and concept mapping. Benefits and application of…

Describes four experiments that enable students to explore the phenomena of evaporation and condensation and determine the relative humidity by measuring air temperature and dew point on warm September days. Provides tables to calculate saturation points and relative humidity. (MDH)

Provides instructions to build an inexpensive device to demonstrate wave-motion to elementary school children. (MDH)

Some ways in which exploratory activities of the preschool child involve science concepts are described. The role of adults knowledgeable about both science and child development is stressed. Emphasis is placed on hands-on experiences. (EB)

Reports findings of a study on children's perceptions and alternate conceptions about the human circulatory system. Summarizes the responses of fifth and eighth grade students on questions dealing with the heart and blood. Offers examples of hands-on activities and confrontation strategies that address common misconceptions on circulation. (ML)

Provides examples of science activities in which children use their senses in manipulating objects and ideas. Suggests that these and other activities be extended to help children deepen their understanding of scientific concepts. (JN)

An activity in which children can learn the concept of the sizes of planets in comparison to the size of the earth is described. Activity questions are included. (SA)

Demonstrations are presented in which children can be introduced to evidence of specific concepts enabling them to participate in such a way that any conceptual conflicts that might arise in this learning situation can be gradually reduced. (EB)
