This study describes how students' intuitions about sampling are informed by extended experiences in investigating local ecosystems. Elementary students in a rural/suburban district in the upper midwest spent a year conducting first-hand comparative field studies of nearby ponds, prairies, and forests. At the close of the term, we conducted…

Taking a sociocultural perspective, this qualitative case study aims to contribute, investigate, and understand how young Mexican American emergent bilingual learners engage in early science experiences. Furthermore, the study focuses on how the students manifested their knowledge, understanding, and perceptions about science and its…

This article describes a first-grade research project that incorporates trade books and challenges misconceptions. Educators see the power of their students' wonder at work in their classrooms on a daily basis. This wonder must be nourished by students' own experiences--observing the moon on a crystal clear night--as well as by having…

This paper will explain what a reading teacher learned from working with a group of first-grade struggling readers in a series of shared-book experience classes. The shared-book experience approach used a variety of science-themed books that were aligned with the first-grade curriculum and appropriate for beginning readers. Considering the…

This paper reports on the results of several geotechnical engineering-related science activities conducted with elementary-school students. Activities presented include soil permeability, contact stress, soil stratigraphy, shallow and deep foundations, and erosion in rivers. The permeability activity employed the LEGO NXT platform for data…

The purpose of this study was to identify the perceptions of pre-service science teachers about using vee diagrams and preparing electronic portfolios in physics laboratuary course. 103 first grade pre-service science teachers who took general physics laboratuary course were the participants of the study. Pre-service teachers constructed vee…

We explored 30 Black Kindergarten-2nd grade students' spoken narratives around pages of their science journals that the children selected as best for showing them as scientists. Because in all narratives, space-time relationships play an important role not only in situating but also in constituting them, we focused on such relationships using…

Scientific modeling along with hands-on inquiry can lead to a deeper understanding of scientific concepts among students in upper elementary grades. Even though scientific modeling involves abstract-thinking processes, can students in younger elementary grades successfully participate in scientific modeling? Scientific modeling, like all other…

What happens in the first week of school could very well set the stage for the rest of the school year. Setting high standards for science activities based in inquiry can start on the first day of science class and develop as the year unfolds. With the use of simple, readily available, inexpensive materials, an efficient mystery box lesson can be…

This article reports on the study of differential change trajectories for early childhood approaches to learning. A large sample (N = 2,152) of Head Start children was followed through prekindergarten, kindergarten, and first grade. Classroom learning behaviors were assessed by teachers through the Preschool Learning Behaviors Scale twice in Head…

The authors created an interactive reflective log (IRL) to provide teachers with an opportunity to use a journal approach to record, evaluate, and communicate student understanding of science concepts. Unlike a traditional journal, the IRL incorporates prompts to encourage students to discuss their understanding of science content and science…

By thinking about the concept of density and taking into account the research on children's ideas about this concept, the authors were able to unpack the typical sink or float activity and realize that it has students unscientifically making comparisons between objects by changing two independent variables (mass and volume) at one time. With this…

It is common practice for elementary classes to plant seeds so that students have the opportunity to observe them germinate and grow. Beyond introducing plant anatomy, this relatively simple activity has the potential to engage children as young plant scientists who investigate the basic needs and behaviors of plants. In this article, the authors…

The purpose of this paper is to describe and analyze the process of construction of meaning about the shape of the Earth and the alternation of day and night, which is inherent to the practice of experimental science teaching. This teaching practice was gradually done by the researcher in a 1st grade class of a Portuguese primary school. The class…

This article describes the experience of a group of first-grade teachers as they tackled the science process of classification, a targeted learning objective for the first grade. While the two-year process was not easy and required teachers to teach in a new, more investigation-oriented way, the benefits were great. The project helped teachers and…
