An experiment is described that determines the activation energy (E[subscript a]) of the iodide-catalyzed decomposition reaction of hydrogen peroxide in a much more efficient manner than previously reported in the literature. Hydrogen peroxide, spontaneously or with a catalyst, decomposes to oxygen and water. Because the decomposition reaction is…

This paper describes a physics laboratory exercise for determining the coefficient of static friction between two surfaces. The circular motion of a coin placed on the surface of a rotating turntable has been studied. For this purpose, the motion is recorded with a high-speed digital video camera recording at 240 frames s[superscript-1], and the…

Biomimetic replicas of superhydrophobic lotus and taro leaf surfaces can be made using polydimethylsiloxane. These replicas faithfully reproduce the microstructures of the leaves' surface and can be analyzed using contact angle goniometry, self-cleaning experiments, and optical microscopy. These simple and adaptable experiments were used to…

An update to the thermochromic cobalt(II) chloride equilibrium demonstration is described. Filter paper that has been saturated with aqueous cobalt(II) chloride is heated for seconds in a microwave oven, producing a color change. The resulting pink and blue map is used to colorfully demonstrate Le Châtelier's principle and to illuminate the hot…

Development of benchtop, portable Fourier transform nuclear magnetic resonance (NMR) and infrared (IR) spectrometers has opened up opportunities for creating university-high school partnerships that provide high school students with hands-on experience with NMR and IR instruments. With recent changes to the international baccalaureate chemistry…

It has been noted that undergraduate project-based laboratories lead to increased interest in scientific research and student understanding of biological concepts. We created a novel, inquiry-based, multiweek genetics research project studying Ptpmeg, for the Introductory Biology Laboratory course at Brandeis University. Ptpmeg is a protein…

The impact of Physics laboratory on students was carried out among senior secondary school students offering Physics in Ethiope West Local Government Area of Delta State using descriptive survey. Five public schools were random-even samplying technique was adopted for precision. Fifty questionnaires were distributed to students in each school,…

Graphene has opened up new opportunities for scientific and technological innovations because of its astonishing electrical, mechanical, chemical, and thermal properties. For instance, graphene-based nanocomposites have found extensive applications in Li-ion batteries (LIBs) as scientists and engineers seek to achieve superior electrochemical…

Course-based undergraduate research experiences (CUREs) are an effective way to integrate research into an undergraduate science curriculum and extend research experiences to a large, diverse group of early-career students. We developed a biology CURE at the University of Miami (UM) called the UM Authentic Research Laboratories (UMARL), in which…

The study examined the relationship between the secondary school head teacher's leadership roles in delivering the much-needed integrative quality education in Uganda. It also sought to determine the overall effect of the head teacher's leadership role on the school's ability to realize integrative education. Results revealed that there are three…

Recently, medical students' scientific thinking skills have been identified as an important issue in medical education. Scientific thinking cannot be imparted in conventional lectures, but rather requires actively involving students. We modified a practical course in physiology. A study was designed to test whether the new course fosters…

Laboratory-based learning can be weakened by a lack of connection with underlying theory and limited contextualization to enhance motivation. To address these shortcomings, a framework for the development of web-based multimedia prelaboratory modules is proposed. The framework incorporates supportive information (content), utility value (context),…

While a national agenda seeks to make Australian higher education more inclusive for an increasingly diverse student population, the contribution that writing instruction can make to achieving these goals has been overlooked. This article outlines the rationale, development, and growth of the Writing Hub at the University of Sydney to advocate for…

During the fall of 1947, the first building for the Naval Arctic Research Laboratory (NARL) was constructed, which consisted of a quonset hut retrofitted as a laboratory. Scientists arrived in Barrow (Utqiagvik), Alaska, the northernmost village in the United States, not long after. The remainder of NARL was built two miles outside the village…

This research investigated the impact of implementing an asynchronous online academic integrity workshop at the University of South Alabama. The workshop featured interactive modules designed to teach students about ethical conduct, impart study skills correlated with academic integrity, and provide instruction on integrating and citing sources.…
