The crystalline sponge method allows for direct and precise molecular structure determination of liquid and gaseous targets and thus has been recognized as a revolutionary breakthrough in crystallography. To expose undergraduates to this cutting-edge technique, we have developed a comprehensive laboratory experiment with reaction conditions and…

Nowadays, students have digital skills that are much larger than any other student in the past. Traditional experiments in a real laboratory are still fundamental, however an increasing number of computers can be used to simulate experiments close to the experimental environment. This can be seen as a great advantage for science learning, as…

A Maker-oriented experimental course in general chemistry has been created by using digital tools, such as a computer, a pressure sensor, and data processing software, in combination with a new multiple expansion method and laboratory equipment to determine the vapor pressure precisely. In this Maker chemistry experiment, the pressure sensor…

Science education at different levels can be supported by various mobile applications that can be downloaded for free onto mobile phones, tablets, and other devices. Such applications can also be used in laboratory work, but it must be said that their use in science laboratories is a relatively new approach. This study is aimed at determining the…

A remote laboratory that measures the enthalpy of vaporization ([delta]"H"[subscript vap]°) and the entropy of vaporization ([delta]"S"[subscript vap]°) of "n"-octane was designed, constructed, and offered to second-year physical chemistry undergraduates at the University of New England (UNE) and Curtin University.…

The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

Ever since Newton's groundbreaking work on the composed nature of light, additive colour mixing (and its laws) are subject to the interest of physicists as well as other sciences. In this paper, we present a setup for simple lab or home experiments on additive colour mixing and the laws of colour mixing. Students use the screen of a laptop or…

Hands-on experiences in analytical chemistry laboratories are essential to improve students' technical skills on handling analytical glassware and instruments, but the coronavirus pandemic in 2020-2021 disrupted such learning activities. Thus, alternative remote activities are required to supplement practical skills. In this work, a new portable…

In this communication, we describe five at-home laboratory experiments and demonstrations that complement a semester-long analytical chemistry curriculum. The experiments were successfully carried out by remote undergraduate students enrolled in a hybrid analytical chemistry course during the COVID-19 pandemic. Students used their personal…

The dehydration of 2- or 4-methylcyclohexanol to obtain isomers of methylcyclohexene is a classic organic chemistry experiment. Students perform a distillation, collecting samples to analyze the progress of the reaction. The reaction produces a major product that can be explained on the basis of the regiochemistry of the [pi] bond formation for…

Supersonic free-fall jumps are excellent examples of kinematics in the context of drag. They have attracted a lot of media, public, and scientific interest. In 2012, Felix Baumgartner jumped from a height of approximately 38.969 km. During his flight he reached a top speed of 373 m/s, becoming the first human to travel faster than the speed of…

Virtual labs provide space for students to iteratively test, observe, and revise their understanding so as to improve their scientific literacy. However, one of the challenges that students face is that they need to think and act like scientists so as to be sensitively alert to methodological flaws and various sources of error. This study thus…

The aim of the present research is to determine the current situation in the readiness levels of 11th grade high school students for self-directed learning, to examine the effectiveness of laboratory activities developed with with mobile technology integrated into the 5E learning model in various chemistry subjects on students' self-directed…

A Microsoft Excel workbook has been developed to simplify the quantitative analysis of experimentally measured titration curves for diprotic and triprotic amino acids such as glycine, arginine, histidine, and glutamate. Students perform the titration, enter the data into the worksheet, and manually adjust the resulting pK[subscript a] values to…

Research exploring students' learning from physical and virtual labs has suggested that on the whole, students learn science content just as well, if not better from virtual labs as they do from physical labs. However, the affordances of physical labs might support the learning of specific skills and competencies that are just as crucial for…
