Catalysis Revisited An Overview of Classical school experiments and New Approaches for a Better Conceptual Understanding Marco Reinmold, Julian Grob, Bastian Hohm, Arnim Lühken World Journal of Chemical Education. 2023 11 (3). doi: 10.12691/wjce-11-3-14 Keywords: Catalysis, kinetics, reaction order, homogeneous, heterogeneous, enzyme catalysis, photometry, BYOD, content knowledge, conceptual understanding, classical school experiments , new approaches, hands-on experiments, easy to perform Context: ...t contexts of green and sustainable chemistry. To promote such an adequate conceptual understanding, this article presents five school experiments . The experiments allow high school students to acquire the concepts of kinetics and catalysis in a technically correct mann... Abstract Full Text (PDF) [Epub] Full Text (HTML)

Electrolysis of Water in school experiments – Simple and Safe Model Experiment for Hydrogen Production Using Everyday Materials for Teaching Purposes Dominique Rosenberg, Tom Severin Gabriel, Maike Busker, Sven Gehbardt World Journal of Chemical Education. 2025 13 (4). doi: 10.12691/wjce-13-4-1 Keywords: Hydrogen, Electrolysis, Energy supply, Model tests, school experiments Context: Hydrogen is becoming increasingly important as a versatile energy source in society and industry across various sectors. It is obtained through the electrolysis of water, in which water is split electrolytically into oxygen and hydrogen. The production of hydrogen through electrolysis is an excellent way to teach students key aspects of modern energy storage and the energy transition in a clear and concise manner. However, simple, safe, and inexpensive experiments are particularly important in school lessons. The model experiment presented here shows how the electrolysis of water can be carried out successfully and safely using readily available everyday materials. Both technical fundamentals and safety-related aspects are taken into account. Abstract Full Text (PDF) [Epub] Full Text (HTML)

school experiments on Different Lithium Batteries Dominique Rosenberg World Journal of Chemical Education. 2023 11 (3). doi: 10.12691/wjce-11-3-16 Keywords: lithium batteries, lithium-manganese dioxide-batteries, lithium-pyrite-batteries, lithium-iodine-batteries Context: Lithium-ion based batteries are the most commonly used energy storage systems for electronic systems like tablets, smartphones, etc. in present times. Moreover, lithium ion-batteries are “the beacon of hope” for the automotive industry for the use in electric and hybrid cars and for the energy revolution to be applied as a short-time energy storage. However, other lithium-metal-based batteries are used in everyday life, such as lithium-manganese dioxide battery or lithium-iodine-battery. These types of batteries are much less known, but are used very frequently in everyday life. In this article simple experiments with lithium-batteries are presented.
