This article describes how observing whether objects sink or float in water using the P-E-O (Predict, Explain, and Observe) technique is an elementary precursor to developing explanations in later grades that involve an understanding of density and buoyancy. Beginning as early as preschool, elementary students engage in activities that encourage…

Since the 1970s, a small but committed group of educators and developers has been encouraging students to learn the language of technology: computer programming. This article describes how today those efforts are moving forward, as a number of kid-friendly languages are being developed with the goal of harnessing students' attention and…

Despite the pressures on education and educators today -- seemingly from all sides -- science teachers provide critically important opportunities for students to develop the scientific knowledge and skills they will need as adults. This preparation empowers them to make well-informed decisions as citizens, as well as to use this knowledge as a…

Earth's surface is constantly changing. Weathering, erosion, and deposition break down Earth materials, transport those materials, and place them in new locations. Children see evidence of these processes all around them. The sidewalk or playground surface cracks and has plants growing in it. Pieces of a rock wall or the sides of a building…

How the heart works is found in "A Framework for K-12 Science Education" and connects to Life Sciences Core and Component Ideas, From Molecules to Organisms: Structures and Processes (NRC 2012). By the end of grade 2, students should understand that all organisms have external parts, which they use in various ways to seek, find, and take…

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa's 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers…

In this article, Clare Rees describes the interest of staff and children alike when their school added the newest and possibly coolest iPad "tablet computers" to the classroom. Everyone wanted to get their hands on them. But how were they going to use them as teaching and learning tools? How were they actually to be used in the…

Recent comparative data on high school graduates show that many American students are not well prepared in fields of science, technology, engineering, and mathematics and that there is a persistent achievement gap according to the socioeconomic backgrounds of students. The research for this paper focuses on the role of elementary education in…

This ethnographic research examines how children enact developing understandings in science through multiple interactions. Grounded in sociocultural theoretical frameworks, we consider learning to be a social, cultural practice, with understandings as co-constructed between participants through talk and in interactions. With these underpinning…

We present a collection of analogies that are intended to help students better understand the foreign and often nuanced vocabulary of the genetics curriculum. Why is it called the "wild type"? What is the difference between a locus, a gene, and an allele? What is the functional (versus a rule-based) distinction between dominant and…

In this paper, we investigate how elementary school students develop multi-level explanations of population dynamics in a simple predator-prey ecosystem, through scaffolded interactions with a multi-agent-based computational model (MABM). The term "agent" in an MABM indicates individual computational objects or actors (e.g., cars), and these…

The Northern Ireland Primary Curriculum, formerly a highly prescribed, content-rich programme in which science was a discrete subject, was revised in 2007 and made statutory for all year groups by 2009. One of the most significant changes has been the amalgamation of science and technology with geography and history under a single area of learning…

What better way to engage young students in physical science concepts than to have them engineer flying toy rockets? The integration of engineering into science classrooms is advocated by the "Next Generation Science Standards" (NGSS) and researchers alike (Brophy et al. 2008), as engineering provides: (1) A "real-world…

One-day chemistry camps, managed by graduate students from the Departments of Chemistry at the Universities of Virginia (UVA) and Vermont (UVM), have proven successful as an outreach initiative. The camp model engages kindergarten through fifth grade elementary school students in hands-on, inquiry-based science experiments to educate and excite…

In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on…
