Povzetek – Razmišljanje srednješolskemu učitelju fizike ponuja nekaj mogočih poti do izkoristka toplotnih strojev in do entropijskega zakona. Pri tem se opre na energijski zakon in na plinsko enačbo, ki ju dijaki poznajo. Kot pomoč vpelje entropijski izrek. Ostaja v okviru termodinamike in ne predre do molekulske slike. Ob tem opozori na nekatere pasti. Sestavlja okostje, ki mu učitelji po svojem premisleku lahko dodajo meso.

Abstract – This deliberation offers to the high school physics teacher some possible ways to the efficiency of thermal engines and the entropy law. It is based on the energy law and the molar gas equation that are known by students. As a remedy the entropy theorem is introduced. It remains within the realm of thermodynamics not progressing to the molecular viewpoint. Thereby the attention is called to some pitfalls. A skeleton is presented to whom flesh can be added by the teacher according to her or his preferences.

Abstract – The article presents the instructions for a matura - lab (a graduating student's lab) experiment.
The author describes the equipment used with accompanying photos. As an exprienced teacher, he comments on the students' method in carrying out the experiment. To conclude, the results obtained by 2 students, were presented in a lab report.

Abstract – Interesting and unusual properties of modern materials can be used as an instructional method through which students can learn about physics as a modern science, a science of the future, whose technological applications are to have a great impact on their present and future lives. Students' motivation and consequently, popularisation of physics greatly depends on their teacher's innovative approaches. Well thought out methods of introducing modern, inexpensive materials in physics classroom can enhance learners' awareness of the breadth, beauty and usefulness of the subject. The article presents some simple experiments which can have a great motivational impact and contain lots of physical wisdom. Properties of pyrolytic graphite, nickel-titan alloys, aerogel,… and possible ways of integrating them in teaching physics are included. Finally, a procedure of making lenses from wax, suitable for project days and experimental work, is described – as a way of rounding up the chapter on light and optics.

Abstract – Nikola Tesla’s student days are described including his unscholarly affair in Maribor. The achievements of Tesla’s most influential professors Martin Sekulić and Jakob Pöschl are put into the limelight.
