- Hubeňák J.: Modern Photometry – Using a Phototransistor And a Multimeter, Fair 8, České Budějovice 2003A guide on how to make a simple probe for measuring light intensity using a phototransistor. Procedure for measuring the angular dependence of light bulb and LED light intensity (the outcomes are plotted in polar graphs) and a calculation of a quantum efficiency of LED. Making of a polarizing filter from a mobile phone display, a measurement of light bulb and LED light polarization.
- Jílek M.: Experience Physics, Fair 8, České Budějovice 2003Seven experiments to enliven physics lessons or seminars and hobby groups (centrifugal force, shooting into wooden blocks, Brownian motion, equilibrium state, energy of a spring, Faraday cage, electromagnetic induction)
- Polák Z.: CD Experiments, Fair 8, České Budějovice 2003Measuring 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.
- Vícha V.: The Propeller in Lab Exercises, Fair 8, České Budějovice 2003Three ideas for laboratory exercises (Rotation movement, Propeller and a monitor, Draw force of a propeller) and one problematic experimental task (Propeller as a balance wheel) with a simple propeller.
