Pigments, dyes, and transition-metal compounds are made in courses across the undergraduate chemistry curriculum, but student characterization of these compounds' most striking features, their colors, seldom goes beyond verbal descriptions. Affordable, hand-held, fiber-optic reflectance spectrophotometers make it possible to advance students'…

To address the need for physics courses that stimulate non- STEM majors' interest in, and appreciation of, science, the Department of Applied Physics has developed a popular course for Yale College undergraduates, The Technological World, that explains the physics behind technologies that students use every day. The course provides an in-depth…

Factors such as innovations brought in by the developing technology, also rapidly changing social structures casted various roles to both the student and the teacher. Therefore, it is necessary to associate such knowledge acquired in courses with implications of the knowledge in our real lives and to constantly enrich course contents, namely to…

"How does an aircraft fly?" is one of the most frequently asked science questions by young pupils. The lift on airplane wings also makes a great example of the application of the Bernoulli principle while teaching fluid mechanics in introductory physics and engineering courses. The topic is of great interest and is therefore covered in…

In the race towards achieving the Education 2030 agenda, open educational resources (OER) act as a key enabler for sustainable development goal 4 (SDG4). Leading to the 2014 Regional Focal Points Meeting, Commonwealth of Learning's (COL) Focal Point for Tonga had identified top priorities for the country where COL can further support the national…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

The lifetimes of the photoluminescent compounds contained in the coating of fluorescent compact lamps are usually measured using specialised instruments, including pulsed lasers and/or spectrofluorometers. Here we discuss how some low cost apparatuses, based on the use of either sensors for the educational lab or commercial digital photo cameras,…

Ghanaian education industry, especially at the tertiary level has witnessed progressive growth over the years. As a result of this, technology is required to sustain this progress since technology has become a powerful tool for women to further their education without experiencing any role conflict. However, of great concern are the challenges…

Advances in electronics technology have transformed the cockpits of large and small modern aircraft. This transformation has created new challenges for the aviation electronics industry and the technicians that support and maintain aircraft. To meet these challenges, it is important to know the knowledge skills, and abilities required by these new…

The basolateral amygdala (BLA) modulates memory consolidation for a variety of types of learning, whereas other brain regions play more selective roles in specific kinds of learning suggesting a role for differential consolidation via distinct BLA pathways. The ventral hippocampus (VH), an efferent target of the BLA, has been suggested to…

Rodents are exquisitely sensitive to light and optogenetic behavioral experiments routinely introduce light-delivery materials into experimental situations, which raises the possibility that light could leak and influence behavioral performance. We examined whether rats respond to a faint diffusion of light, termed caplight, which emanated through…
