In 1849, Hippolyte Fizeau determined the speed of light in a famous experiment. The idea was to measure the time taken for a pulse of light to travel between an intense light source and a mirror about 8 km away. A rotating cogwheel with 720 notches, that could be rotated at a variable speed, was used to chop the light beam and determine the flight…

To improve the teaching and learning materials for a curriculum it is important to incorporate the findings from educational research. In light of this, we present creative exercises and experiments to elicit, confront and resolve misconceptions in geometrical optics. Since ray diagrams can be both the cause and the solution for many…

Prior to the recycling process, raising awareness of plastic waste impact, e.g., polluting oceans worldwide, is undoubtedly a first attempt to tackle this pandemic environmental issue. With this in mind, the presented practical session is an effort to entice an interdisciplinary audience of science undergraduates toward a sustainable future. The…

Within the framework of the Lisbon Agreement, all European member states are encouraged to take measures to increase the number of science and technology students in higher education. To promote this educational model, a chemistry project was developed that focuses on high school students and especially on the involvement of their teachers by…

Citizen science is a term used to describe the engagement of ordinary citizens in scientific tasks like observation, measurement, and computation. A series of technological innovations, such as the Internet, the upgrade of mobile phones from communication devices to networked mobile personal measurement devices, and the introduction of…

Synthesis of pure enantiomers is a key issue in industry, especially in areas connected to life sciences. Catalytic asymmetric synthesis has emerged as a powerful and practical tool. Here we describe an experiment on racemic reduction and asymmetric reduction via a catalytic hydrogen transfer process. Acetophenone and substituted acetophenones are…

Discusses the history of open-air schools using an evaluation of Belgian schools. Expounds on the complex relationship between educational space and the educational act, and between traditional and progressive education. Demonstrates that open-air schools provided the same education as traditional schools and were not a real alternative for…
