Students determine the iron mass in dietary supplements using four colorimetric assays. These colorimetric assays were selective for Fe[superscript 3+]. It was complexed by thiocyanide, salicylate, gallic acid, and Fe(CN)[subscript 6][superscript 4-], forming blood-red, red, violet, and blue complexes, respectively. The [lambda][subscript max] of…

For decades safety has been an integral component of STEM (science, technology, engineering, and mathematics) and CTE (career and technical education) instruction. Given today's litigious society, safety in P-12 STEM education and CTE has received greater attention. This in part is the result of the rise in popularity of collaborative learning…

A problem-based learning activity focusing on the human impact on the environment and the importance of sustainable development is presented. The activity revolves around a mysterious island where the civilization is on the blink of extinction, prompting students to investigate how human behavior, ecosystems, resources, and natural balance…

Barriers to women's education and employment in Europe and the United States in the 19th century made it unlikely that any women would be among the few physicists whose ideas are taught in high school and college courses. This paper explores the social settings in which three influential physicists worked--James Clerk Maxwell, Robert Millikan, and…

Many teachers do not notice, or do not understand, the chemistry going on in and around their homes and hence do not point it out to their students. Thus they miss out on an important motivating experience. This article gives a few random examples, most of them well within the understanding of students at key stages 3 and 4 (age 11-16). From…

Citizen science can provide insightful data to inform decisions, while also serving to enhance ecological awareness and foster environmental stewardship among participants. In this article, high school student citizen scientists investigate how trees respond to changing mountain climate during a field trip to Rocky Mountain National Park (RMNP) to…

This year marks the U.S. National Park Service's 100th anniversary. Although the nation's first national park--Yellowstone--dates to 1872, the government organization protecting and administering the national parks was founded just a hundred years ago, in 1916. Many U.S. national parks were established to preserve their unique geology or biology.…

The core practice of professional scientists is inquiry, often referred to as research. If educators are to prepare students for a role in the professional scientific and technological community, exposing them to inquiry-based learning is essential. Despite this, inquiry-based teaching and learning (IBTL) remains relatively rare, possibly due to…

This article describes a second grade science enrichment unit with a focus on human impact, both positive and negative, on the living and nonliving components of the local watershed. Investigating the local watershed gave the unit a personal and pragmatic connection to students' lives because they depend on the local watershed for what they need…

Despite decades of effort by federal science funders to increase the numbers of women holding advanced degrees and faculty jobs in science and engineering, they are persistently underrepresented in academic STEM disciplines, especially in positions of seniority, leadership, and prestige. Women filled 47% of all US jobs in 2015, but held only 24%…

Integrating engineering and science in the classroom can be challenging, and creating authentic experiences that address real-world problems is often even more difficult. "A Framework for K-12 Science Education" (NRC 2012), however, calls for high school graduates to be able to undertake more complex engineering design projects related…

The decline in hummingbird populations and shifts in their movements may adversely affect their role as pollinators and, in turn, plant biodiversity (Allen-Wardell et al. 1998). For example, Hadley et al. (2014) discovered that larger fragments of forest correlated with larger hummingbird populations and more seeds of "H. tortuosa" being…

In the DISCUSS (Dialogic Inquiry for Socioscientific and Conceptual Understanding in School Science) research project, a Socioscientific Issues (SSI)-based curriculum is developed and implemented in sixth-grade science classrooms with predominantly English language learners (ELLs) in Houston, Texas. A four-week space unit is designed in…

During the last decade of the 20th century (the decade of the brain) large sums of money were spent in researching how the brain works in relation to our day-to-day activities. As a result, we now know to a much greater extent the roles played by various regions of the brain when we are carrying out various activities including learning. We also…

This edited volume presents innovative current research in the field of Science Education. The chapter's deal with a wide variety of topics and research approaches, conducted in a range of contexts and settings. Together they make a strong contribution to knowledge on science teaching and learning. The book consists of selected presentations from…
