Despite many research studies showing the effectiveness of teacher application of child-centered learning in different educational settings, few studies have focused on teaching and learning activities in Pre-Schools. This research investigates the effect of child centered methods on teaching and learning of science activities in preschools in…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

Describes activities for the elementary school classroom to increase observational accuracy of children. (CP)

Describes how raising monarch, black swallowtail, and mourning cloak butterflies in a kindergarten class garden can provide opportunities for observation experiences. Includes detailed steps for instruction and describes stages of growth. Excerpts children's journal dictations to illustrate ways to support the discovery process. Describes related…

This activity is more concerned with illustrating the process of scientific discovery than with astronomy. Students are involved in observing the Moon and noting the simultaneous location of the Sun. A manual with observation log and diagrams is provided. Requires no special equipment and takes a discovery learning approach. (LZ)

Presents investigations in which students are provided with a series of four mystery items related to cicadas. Observations and a class discussion follow each item. Contains basic information on doing experiments with live cicadas, specific assessment strategies for this activity, and facts about cicadas. (DDR)

Presents activities that utilize balloons to encourage students to explore questions related to scientific concepts. Concepts explored include light, heat, charged ions, polarization, and the sense of smell. (MDH)

Reports and discusses observations of three confident, experienced teachers organizing investigative science in their classrooms. The teachers wore microphones and the recorded data coupled with field notes formed a record of what happened that could be negotiated with the teachers. (DDR)

Students test the hypothesis that the moon revolves east to west around the earth, determine by observation approximately how many degrees the moon revolves per night, and develop a scale model of the earth-sun-moon system in this laboratory exercise. Students are actively involved in the scientific process and are introduced to the importance of…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

Presents an activity in which students develop science process skills by making inferences as to the contents of a "mystery" box from observations based on their sensory perceptions. Provides instructions for implementing and extending the activity. (MDH)
