This report describes an inquiry-based Earth systems curriculum and strategies for teaching diverse students, which were embedded in the curriculum. The curriculum was implemented with 5th-grade students with varied linguistic, cultural, and socioeconomic backgrounds in five schools in a large, southeastern U.S., urban school district. At the end…

This paper reports a study on elementary students' ideas regarding changes in mass associated with melting. An open-ended probe was designed and distributed to fifth-grade students (n = 230). In addition, 50 students were asked their reasons behind predictions on mass change. The written responses indicate that, despite conventional teaching,…

"How much popcorn will our classroom hold?" This intriguing question sparked a terrific integrated science and math exploration that the author conducted with fifth-and sixth-grade students. In the process of finding the classroom's volume, students developed science-process skills (e.g., developing a plan, measurement, collecting and interpreting…

A phenomenological approach was used to investigate the longitudinal recollections of participants of an out-of-school science program. The experience was a field trip to the Shenandoah National Park (USA) conducted in the fall of 2004. The science topic was geologic history and features related to the Shenandoah Valley. Two major themes relating…

Although weather, including its role in the water cycle, is included in most elementary science programs, any further examination of raindrops and snowflakes is rare. Together rain and snow make up most of the precipitation that replenishes Earth's life-sustaining fresh water supply. When viewed individually, raindrops and snowflakes are quite…

This work describes an experimental research on note taking and concept mapping in a science class of 5 graders in Kayseri (Central Anatolia, Turkey) in the academic year 2002-2003. Gained results are in favor of convictions that view note taking as an effective learning strategy. At least it was more effective than concept mapping in the…

At home, children often have pets that they take care of and play with; even in the classroom it is not uncommon to find a wormery, an aquarium or an ant farm. However, children rarely have the opportunity to own and care for a plant over a lengthy period of time, let alone a tree. The authors describe a project in Portugal aimed at improving…

While observation is critical to science, sometimes things cannot be observed directly. Sometimes things happened long ago (in paleontology, for example) or are too small to observe (like atoms). Many students believe that science progresses only through direct observation. Students may also believe that giant microscopes provide insight into…

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.…

The purpose of this research project was to determine the effects of incorporating concept mapping on the achievement of fifth grade students in science class. The study was conducted with twenty-three students at Ata Elementary School, Trabzon, Turkey. The students were tested with teacher-constructed pre- and post tests containing 20…

In this article, the authors present hands-on activities and demonstrations using readily available materials that help students learn how to prevent soil erosion. With this series of active-learning exercises, the students will be able to practice scientific inquiry while learning about soil as a valuable resource. After demonstrations on the…

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3-8. Each unit uses computers and probeware to support students' investigations of real-world phenomena using probes (e.g., for temperature or…

Although there is a considerable emphasis on inquiry-based, active learning in standards documents, curriculum documents, and textbooks, there exists a great deal of debate regarding the effectiveness of specific curricular and instructional approaches, including kit-based instruction. This study examines the efficacy of science kits in improving…

This article explores the potential of using students' science notebooks to help elementary teachers monitor conceptual understanding. Data came from 25 teachers and their 4th- and 5th-grade students working on a unit on electricity. At the time data were collected, 8 of the teachers had received professional development on science content…

Current educational policy highlights the important role that assessment can play in improving education. State standards and the assessments that are aligned with them establish targets for learning and promote school accountability for helping all students succeed; at the same time, feedback from assessment results is expected to provide …
