I got something cool for my birthday: a hot tub! So I asked myself if these things are any good at all and if they are stable. After all, they are quite expensive! The setup took a solid 45 minutes. Filling it with water using a garden hose took another 1.5 hours. The water had about 24° Celsius d

"Active learning" means getting involved, collaborating with others, and implementing concepts in the real world. It is intellectual hard work. But it allows you to remember the content better, understand it better and transfer it to other situations. Why does it work so well? We take a look at th
"Active learning" means you participate, collaborate with others, and apply concepts to the real world. It requires hard mental effort but leads to better retention and an understanding of the material that can be transferred to other situations. To explain how to apply Active Learning in classrooms
The reaction speed of the enzyme-catalyzed reactions depends on various factors. In this screencast, the dependence on the substrate concept is explained and the curve is derived. Finally, the Michaelis constant is described. Original: "Wolfgang Dukorn" Original: German. All translations in this v

Impulse video: It's all about the distinction between the reaction equation and the reaction mechanism. This video is intended to prepare for the lesson. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Using the example of the reaction between water and oxygen, the essential statements of a chemical reaction are described. What quantities of substances must be used? What does this mean for their masses? This is an introduction to stoichiometric calculations! Original: "Wolfgang Dukorn" Original:
On the basis of an example problem, the stoichiometric calculations in chemistry are explained. It calculates the mass of a product when only a certain mass of a starting material is available. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugh
Very short description of how the oxyhydrogen test is carried out and what observations are to be made. A detailed discussion of the results will not take place at this time! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
A reaction equation with molecules and salts (possibly also with metals) together is very demanding for the initial lessons. How to proceed and also how to comply with the law of conservation of mass follows in this screencast. Original: "Wolfgang Dukorn" Original: German. All translations in this
Van der Waals forces, dipole-dipole interactions and hydrogen bonds are explained. It is briefly repeated again how the polarity of molecules can be determined. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
