- Degro J.: Experimenting with a luxmeter and exploring illuminance, Fair 12, Praha 2007This contribution represents experiments and project with a photometer and illumination, which can be conducted with high-school students or elementary-school students.
- Jarosz J., Szczygielska A.: We live on Earth – the rotating system, Fair 12, Praha 2007This contribution describes simple experiments demonstrating the Earth rotation, i.e. the Earth is a non-inertial system. For this demonstration a mechanics model is used – a rotating board. The contribution also includes the explanation of inertia force, Foucault pendulum, creation of cyclones and hurricanes etc.
- Milbrandt R.: Public Demonstration Shows, Fair 12, Praha 2007This presentation discusses public demonstration shows, benefits and goals of such shows, and it discusses in detail two pressure demonstrations: balloons under a large piece of wood with people atop, and a bed of nails with some modifications.
- Patč B.: The effect of low and high pressure on electric current in a gas, Fair 12, Praha 2007This contribution describes a construction of simple devices and the method of an experiment demonstrating the effect of high and low pressures on electric current in gas.
- Piskač V.: Three new experiments, Fair 12, Praha 2007The first part of this contribution is a demonstrative experiment –a light bulb rheostat changes a current in a circuit. The second part deals with acoustic devices (Seebeck siren and monochord), demonstrated by electromagnetic detectors.
- Trzebuniak A.: The experiment sets with many questions, Fair 12, Praha 2007A simple experiment regarding electromagnetic induction, complemented with a four-question course. Students answer these questions and verify their answer by the experiment. The correct answers can be surprising. Contribution also includes a discussion of correct answers.
