"Nuu Savi" ("Sacred Rain's collectivity"), the Mixtec people of southern Mexico, had created some of the most complex polities in the continent at the time of European contact. Five hundred years later, they remain cohesive, culturally distinct communities, as increasing numbers of individuals and families migrate to northern…

Understanding complex systems such as ecosystems is difficult for young K-12 students, and students' representations of ecosystems are often limited to nebulously defined relationships between macro-level structural components inherent to the ecosystem in focus (rainforest, desert, pond, etc.) instead of generalizing processes across ecosystems…

AAAS (American Association for the Advancement of Science) is collaborating with BSCS (Biological Sciences Curriculum Study) in the development of a curriculum unit for eighth grade students that connects fundamental chemistry and biology concepts to better prepare them for high school biology. Recognizing that teachers play an influential role in…

Western red cedar leaf affords an essential oil characterized by high thujone content. Students in an advanced organic chemistry lab course isolate a single thujone diastereoisomer from commercially available cedar leaf oil. Treatment of crude oil, containing roughly 70% thujone, predominately as [alpha]-thujone (6.5:1), with ethanolic sodium…

Water transport in tall trees is an everyday phenomenon, seldom noticed and not completely understood even by scientists. As a topic of current research in plant physiology it has several advantages for presentation within school physics lectures: it is interdisciplinary and clearly shows the connection between physics and biology; the…

Misconceptions are not simply factual errors or a lack of understanding, but rather explanations that are constructed based on past experiences (Hewson and Hewson 1988). If students' misconceptions are not directly engaged in the learning process, they may persist--even when faced with instruction to the contrary (Bransford, Brown, and Cocking…

Processes that transform carbon (e.g., photosynthesis) play a prominent role in college biology courses. Our goals were to learn about student reasoning related to these processes and provide faculty with tools for instruction and assessment. We created a framework illustrating how carbon-transforming processes can be related to one another during…

Science expositions at the Canning River Eco Education Centre (CREEC), Perth, Western Australia, have been conducted over the last five years (2009-2013) during National Science Week. These expos aimed to enhance science understanding in the community, foster partnerships for science and promote science careers by providing a scientific feast for…

Researchers suggest there is an increasing apathy in the study of natural history in academic settings and in the scientific community. However, most studies of environmental knowledge do not address knowledge of local flora and fauna; they are concerned with the knowledge of environmental issues or broad ecological knowledge. Ecoliteracy…

Institutions of higher learning are recently being held more accountable for the learning outcomes of their students. As such, universities have begun to actively measure and evaluate student learning and motivational outcomes in an effort to improve the successful outcomes of their students. To support this work, two studies were conducted to…

Photosynthesis may be an unlikely topic to inspire an opera or ballet, but in a 2nd grade classroom in Pikesville, Maryland, the children were asked to use dance to help them learn about that process. Small groups of pupils in this class at Fort Garrison Elementary School brainstormed to come up with dance movements to convey elements of…

Whether celebratory or critical, STS research on science-industry relations has focused on the blurring of boundaries and hybridization of codes and practices. However, the vocabulary of boundary and hybrid tends to reify science and industry as separate in the attempt to map their relation. Drawing on interviews with the head of a research center…

The purpose of this study was to assess children's understanding of plant nutrition. The research was done on a sample of secondary school pupils in the age range of 16 to 19 years in two senior secondary schools in Botswana. The sample contained 137 senior secondary pupils all in their final year of study. These children were above average…

Charles E. Bracker was a professor of botany and plant pathology at Purdue University from 1964 to 1999. His late wife, Anri, was an orchid enthusiast who began collecting and housing orchids in the 1980s. In 2009, Bracker's 30,000 digital orchid photographs were donated to Ball State University Libraries, where both of this article's authors…

At its Wakehurst Place garden in West Sussex, the Royal Botanic Gardens, Kew, has established the UK home of one of the world's largest conservation projects, the Millennium Seed Bank (MSB) partnership, a global project to conserve biodiversity by collecting and preserving seeds. This article describes what the MSB partnership does, how seeds are…
