The Kicking Mule Brewing Co. at West Point enables members of our chemical engineering club, students, and beer enthusiasts alike to acquire chemical engineering acumen, knowledge, and skills by developing a tangible product. Through a rigorous on-site brewing process with subject matter experts, our goal is enhancement of student chemical…

Science popularisation festivals attract more and more people every year, showing that there is a need to satisfy public curiosity. Such events are good occasions to disseminate knowledge to a large audience. The results of scientific research bring advances for mankind. Since research mostly depends on public funds, it is important to gain…

In tabletop games involving dice, it is important to ensure randomness of the dice rolls and to protect other gaming elements from being scattered by rolling dice. One way of ensuring random rolls and protecting gaming elements is to drop dice into a dice-rolling tower ("dice tower"). A dice tower is usually small (20 cm by 20 cm) and…

This article develops an emergentist theory of children's agency. To make this claim, it first identifies the following two predicaments that scholars have faced in children's agency research: (1) social ambiguity in distinguishing children's learning from adults' guidance; and (2) causal uncertainty between children's cognitive development and…

Two wires exit a black box that has three exposed light bulbs connected together in an unknown configuration. The task for students is to determine the circuit configuration without opening the box. In the activity described in this paper, we navigate students through the process of making models, developing and conducting experiments that can…

Because school laboratory activities obtained by pre-service teachers tend to use cookbook experiments, this study focused on redesigning chemistry laboratory activities at the university level from cookbook experiments to inquiry-based Science, Environment, Technology, and Society (SETS) approach, and analyzing pre-service chemistry teachers'…

Saccharin (1,2-benzisothiazole-3-one 1,1-dioxide) is an artificial sweetener used in the food industry. It is a cheap and easily available organic compound that may be used in organic chemistry laboratory classes for the synthesis of related heterocyclic compounds and as a derivatizing agent. In this work, saccharin is used as a starting material…

The aims of teaching have evolved along with the society in which we live, from a teaching based in memory to a one that teaches to reason, in order to adapt to the accelerated rate of change imposed by the application of scientific discoveries in our society. We have a society in continuous learning, which requires the ability to reason in order…

The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

Earlier studies have discussed the usefulness of storytelling and hands-on activities when teaching young children science. However, few studies have investigated the use of the two methods in combination. This study reports on five pre-school teachers' experience of combining storytelling and hands-on activities in teaching science and their…

This paper discusses laboratory activities that can improve the meaningfulness of natural product chemistry course. These laboratory activities can be useful for students from many different disciplines including chemistry, pharmacy, and medicine. Students at the third-year undergraduate level of chemistry education undertake the project to…

In this paper, we report an experiment intended as a tool to introduce chemistry and materials science students to several chemical concepts through the determination of the best experimental conditions for the formation of calcium oxide (lime) from a source of high content of calcium carbonate (eggshells). Thermal gravimetric analysis (TGA),…

The laboratory protocol presented here takes about 3 hours to perform and investigates protein and lipid interactions. Students first purify His6-tagged human apolipoprotein A-I (apoA-I) with Ni-NTA affinity resin in a simple batch protocol and prepare multilamellar vesicles (MLV) from pre-dried phospholipid films. When apoA-I is added to the MLV,…

A laboratory experiment was developed to follow the gelation of a polyvinyl alcohol (PVA) solution upon addition of borax by using rotational viscometry. The rheological properties of the gel were examined, measuring the dependence of viscosity and shear stress on the shear rate. Time-dependent studies were also conducted in which the viscosity of…

This paper discusses the importance of one of the most crucial elements in science and technology education: the development of the individual capacity to cope with new problems. Also, discuss the importance of being aware of the existence of "formative objectives" and "tacit knowledge". In the planning of a course, taking into…
