- Koudelková V., Cach R., Polák Z., Reichl J.: A few things from the summer camp – this time on the topic: “What already the ancient Greeks knew … and do we know it too?”, Fair 17, Praha 2012
This paper describes seven selected projects which were conducted by the Maths and Physics Camp participants, which took place in Kořenov. It concerns these projects: Heron’s Inventions, Levitating Motor, Pythagorean Scale, Radio for Robinson, Communication With Light, Pendulum Wave and Water Integrator.
- Polák Z.: CD Experiments, Fair 8, České Budějovice 2003
Measuring of mechanical and other properties of a CD, simple experiments with a CD (13 guides in total). A description of some parts of a CD-ROM and eight related experiments.
- Polák Z.: Electromagnetic Waves in Experiments, Fair 16, Olomouc 2011
In this article it is presented how to demonstrate most of the fundamental experiments concerning electromagnetic waves propagation with the use of radio receiver, TV set and video cassette recorder (VCR).
- Polák Z.: Experiments with infrared radiation – suggestions, Fair 15, Praha 2010
This contribution is meant for teachers who are looking for ideas for student individual research work. It shows that simple or easily available tools can help one to study the properties of objects that we cannot perceive by senses.
- Polák Z.: Heat experiments, Fair 10, Praha 2005
This contribution is a guide for construction of an alcohol burner and a calorimeter, utilization of a thermosesitive paper, constructing a heat engine, illustration of a function of so called heat pipe and for “weighing” of heat.
- Polák Z.: Measurement of Air Velocity, Fair 5, Praha 2000
A simple measurement of the speed of air flowing from an air flow generator and, as a bonus, a description of some other experiments (balance wheel, the Cartesian diver, rocket…)
- Polák Z.: Simple Experiments, Fair 7, Praha 2002
A few of simple experiments which can be used either as a demonstration during teaching or as a laboratory work (weighing on a sheet of paper, flexible centre impact, interconversion of electrical and mechanical energy, model of a turbine, Foucault currents, alcohol vapour rocket).
- Polák Z.: Thermocouple as a permanent physics experiment, Fair 25, Praha 2020
The following topics are discussed in this paper: Thermocouple and its place in lessons, manufacturing a metal thermocouple in school conditions, thermocouple thermometer, detection of thermocouple’s small voltages, magnetic field of thermoelectric current, thermoelectric generator as a source of voltage, thermoelectric motor powered by heat from a candle.
