The purpose of this article is to present the properties of cylindrical lenses and provide some examples of their use in easy school physics experiments. Such experiments could be successfully conducted in the context of science education, in fun experiments that teach physics and in science fair projects, or used to entertain an audience by…

"Magic mirrors" were so named because, when they were positioned to throw a reflected patch of sunlight on a nearby wall, this area contained an outline of a design cast on the back of the (bronze) mirror. Investigations begun in the 19th century showed that this was a response to heavy localized pressures exerted on the face of the thin mirror…

We report a laboratory activity, carried out along with high- and secondary-school students, that can be done to increase the interest of the young in scientific studies. Groups of selected students "adopted" experiments at physics research laboratories, under the guidance of university researchers. Subsequently, the students demonstrated the…

This article comes from a question asked by a student of mine: if the Sun radiates energy in the form of electromagnetic waves, could they shift the Earth from its current orbit on a suitable timescale? The answer to such a question is apparently obvious and trivial. Nevertheless, it requires an instructive reasoning and interesting estimates of…

Using first principles, a theoretical equation for the maximum and actual muzzle velocities for a pneumatic cannon was recently derived. For a fixed barrel length, this equation suggests that the muzzle velocity can be enhanced by maximizing the product of the initial pressure and the volume of the propellant gas and decreasing the projectile…

Fieldwork is regarded as an important component of many bioscience degree programmes. QAA benchmarks statements refer explicitly to the importance of fieldwork, although give no indication of amounts of field provision expected. Previous research has highlighted the importance of fieldwork to the learning of both subject-specific and transferable…

The last student enrolled in a pure "Botany" degree in the UK began in the University of Bristol this year, 2010. In recent years only the University of Reading also offered the Botany degree, before it was dropped there 3 years ago. This short article is written to draw attention to this fact and to a more general relative decline in the number…

An artificial, and generally unhelpful, divide between lecturers and students frequently occurs in higher education, especially among recent school-leavers. Bridging that divide allows lecturers and students to develop collaboratively to the benefit of both parties. Residential field courses provide an important forum to develop more mature…

First year undergraduate students at the University of Edinburgh hone their enquiry skills and learn to investigate current environmental issues by carrying out research projects. A list of 60 possible projects has been compiled and is available on a website, to be used directly or adapted to suit the requirements of other educators. This paper…

In this pilot study, a genetics-based laboratory exercise using the cyanobacterium Fremyella diplosiphon was developed and trialled with thirteen Natural Sciences undergraduates. Despite most students only having limited prior exposure to molecular genetics laboratory methods, this cohort confirmed that they were able to follow the protocol and…

Clinical case studies facilitate the development of clinical reasoning strategies through knowledge and integration of the basic sciences. Case studies have been shown to be more effective in developing problem-solving abilities than the traditional lecture format. To enhance the learning experiences of students in biomechanics, clinical case…

This paper describes the design and evaluation of an undergraduate final year science communication module for the Science Faculty at the University of East Anglia. The module focuses specifically on science communication and aims to bring an understanding of how science is disseminated to the public. Students on the module are made aware of the…

This paper outlines the use of item analysis to assist examiners in evaluating the quality and validity of their MCQ exam questions. The generation of item analysis, particularly discrimination index, has long been established practice in professional testing and credentialing organisations and some disciplines in tertiary education, but its use…

The design of experimental ecological fieldwork is difficult to teach to classes, particularly when protocols for data collection are normally carefully controlled by the class organiser. Normally, reinforcement of the some problems of experimental design such as the avoidance of pseudoreplication and appropriate sampling techniques does not occur…

African American adolescents from families with low levels of human capital (i.e., caregiver level of education) are at risk for poor early adult outcomes. The current study examined the relationships among 48 African American high school students' literacy performance (e.g., reading and vocabulary), their implicit views of intelligence, their…
