In this study, we present an activity in which the free-body diagram of a real stationary object on an inclined plane can be examined interactively. We use an Apple Watch and a few other materials that can be accessed easily. Instead of an Apple Watch, a mobile phone or a tablet could also be used. This activity may be employed to introduce the…

The different ways microscale and green chemistry allow reducing the deleterious impacts of chemistry on human health and the environment are discussed in terms of their different basic paradigms: green chemistry follows the ecologic paradigm and microscale the risk paradigm. A study of the synthesis of 1-bromobutane at macro- ? microscale (109.3…

Life would not be possible without plants. Plants supply food to many organisms (including people), produce oxygen, absorb carbon dioxide from the air, provide products for human use, and homes for many other living things. It is not surprising, therefore, that plant growth is a familiar topic in the primary school science curriculum. This paper…

Science is one of the most important subjects for students at all educational levels. To promote engagement, hands-on experiments can provide a 'realistic and exciting experience of the content' (Holstermann, Grube and Bögeholz, 2010: 744) and hopefully facilitate motivation. In this article, George Stylos and Konstantinos T. Kotsis present four…

As a cross-cutting and comprehensive subject, medicinal chemistry involves the knowledge of chemical, biological, medical, and pharmaceutical sciences. A comprehensive medicinal chemistry experience for undergraduates is expected to train various experimental skills and enhance their scientific research ability. Herein, a series of laboratory and…

Despite efforts to incorporate inquiry-based instruction into various science curricular, its adoption has been slow-paced. This has raised many concerns about challenges in the enactment of inquiry-based instruction. Therefore, this article seeks to provide an understanding of the challenges by exploring the perspectives of teachers in the…

Renewable energy is a trending topic due to its importance in today's society especially because of global warming. Because of its importance, this topic should be discussed at schools in an inclusive education environment. Experimental work is a very good activity to provide students effective conceptual discussions, but it is necessary to…

Experiments using smartphones allow for teaching physics concepts in a fun and engaging way and including interdisciplinary approaches. The exploratory character of the experimental activities, along with the smartphones' embedded technologies, when applied in the high school classroom, also has the potential to awake the students' intrinsic…

We describe the design and implementation of a teaching-learning sequence that was started before the lockdown and was then transformed for distance teaching. A backward design approach was adopted in order to identify clear learning outcomes. The activities were outlined according to an inquiry-based learning paradigm, referring to research-based…

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

The hearts of sports fans were stirred recently by the fastest-ever try scored in international rugby. Welsh winger Dafydd Howells crossed the Fijian try line to score a mere six seconds after Angus O'Brien had started the game with a kickoff, in one of the fixtures in rugby's Junior World Cup played on June 2, 2014, in New Zealand. This…

Some misconceptions about physics are hard to change. For example, students continue to believe that heavier objects fall faster than light ones, even after a year of physics instruction. Physics misconceptions are persistent. Light objects do fall more slowly if their size-to-weight ratio is sufficient for drag to be appreciable. Motion through a…

Food spoilage has an enormous economic impact, and microbial food spoilage plays a significant role in food waste and loss; subsequently, an equally significant portion of undergraduate food microbiology instruction should be dedicated to spoilage microbiology. Here, we describe a set of undergraduate microbiology laboratory exercises that focus…

A laboratory project for the upper-division physical chemistry laboratory is described, and it combines IR and Raman spectroscopies with Gaussian electronic structure calculations to determine the structure of the oxalate anion in solid alkali oxalates and in aqueous solution. The oxalate anion has two limiting structures whose vibrational spectra…

A differential scanning calorimeter was used to study homogeneous nucleation of ice from micron-sized aqueous ammonium sulfate aerosol particles. It is important to understand the conditions at which these particles nucleate ice because of their connection to cirrus cloud formation. Additionally, the concept of freezing point depression, a topic…
