Good resources for teaching elementary science content abound, making science more accessible to everyone and helping teachers enhance their presentation of science topics. However, there is one important aspect of science that sometimes proves a bit more difficult to teach: introducing students to the idea of the nature of science. Nature of…

While the sight of a spider may cause a shriek of alarm from an adult, the very same sight might evoke a squeal of delight and fascination from a child. Even "icky" and "gross" creatures can become part of great science lessons. That's the goal of "Spiderrific," a unit of the New Jersey 4-H Science Discovery Series.…

Ask any elementary teacher to discuss the obstacles they face when trying to implement inquiry-based science teaching and you?re sure to hear hands-on materials mentioned. Where to get supplies and how to pay for them, how to organize and store the materials, and how to distribute the materials efficiently during the lessons are constant…

In this investigation, pairs of upper elementary students test germination percentage using seeds of Indian corn ("Zea mays"), scarlet runner beans ("Phaseolus coccineus"), and the prairie cup-plant ("Silphium perfoliatum") grown on rolled, damp paper towels. The pairs compare seeds that have been stratified, a simulation of overwintering and…

The purpose of this paper is to carefully examine the evolution of students' theory building and modeling, critical components of scientific epistemologies, over a unit of study on sinking and floating in one third/fourth grade classroom. The study described in this paper follows in the tradition of Design Experiments (Brown 1992, Collins 1990)…

One activity that gets children thinking about how electricity is made involves exploring hydro (water) power. Water has been used as a source of energy for thousands of years for mechanical purposes such as grinding corn, bellows for furnaces or sawmills for cutting wood or slate. For about a century hydro power has been producing electricity…

Since 1990 the science curriculum in Northern Ireland has gone through three major changes. In the beginning, fifteen attainment targets were introduced to an unsuspecting and largely unprepared teaching population: these were eventually reduced to five in 1993 and then to the present two in 1996. Unlike in England, technology has never stood as…

As science gets squeezed in the elementary curriculum, at least two Florida districts are trying a new approach to keeping hands-on lessons a part of pupils' experiences. This article reports how Broward and Palm Beach county districts have increased the number of science specialists working in their elementary schools--teachers who, like physical…

In this article, fifth graders investigate biographies to expand their knowledge of what real scientists do. The goal of this activity is to find a way to show students that all kinds of people participate in the scientific enterprise. After finding picture-book biographies, the author's next job was to ensure that students saw more than a good…

Members of "Primary Science Review" Editorial Board explain what drew them to science. Alan Peacock, "PSR" Editor, emphasises the need to preserve children's sense of wonderment about the world. Robert Collins, a science educator in the Faculty of Education, University of Strathclyde, thinks people are "secret science…

Elementary students perceive scientists in stereotypical ways. This study examined the influence of historical, nonfiction trade books on children's images of scientists. Of the 13 self-contained third grade classrooms (n = 156), six randomly assigned teachers were instructed to read one trade book each week for six weeks to supplement their…

We focus on the concept of matter and explore how young children in urban schools bridge their spontaneous concepts and everyday experiences with scientific concepts introduced to them by children's literature information books and their teacher. The study shows how material artifacts used in a sorting activity became ideational tools--semiotic…

We analyse two narratives of teacher-facilitator teams producing elementary science curricula and disseminating them to their peers. We draw on these stories to interpret how teacher-facilitators position themselves with respect to other educators (e.g. peer teachers and development-team members), to real and imagined students and parents, to…

This booklet accompanies a videotape covering the same material. It is intended as a guide to performing 16 science demonstrations with young children. Section titles are: "Surface Tension", "Budding Botanist", "Mystery Matter", "Young Rock Stars", "What a Gas!", "Zounds...What Sounds!", and "Brrrrr...Cool Science." Included is a section…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this integration produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…
