- Dvořák L.: A Bit of Heuristics from Malá Hraštice, Fair 5, Praha 2000
A few ideas from the assembly of students of the Department of Physics Education FMP CU. A guide on how to make a string phone with echoes, balance based on the Archimedes’ law, apparatus for measuring the Young’s modulus of jam, dumplings etc., amplifier constructed so that it picks up a magnet pendulum passing through its balance position. Everything is made of commonly available resources.
- Chiaverina C.: Exploring Sound and Light, Fair 15, Praha 2010
This contribution describes five simple experiments which are based on the persistence of vision. Next, a simple phonograph pickup made from a needle and paper, sound transmission via light and other experiments are decsribed.
- Konečný P.: Some experiments with thermosensitive films, Fair 13, Plzeň 2008
This contribution deals with a utilization of reverse thermosensitive foils for detection of temperature changes in experiments demonstrating adiabatic compression or expansion of gas. A demonstration of the 3rd Newton’s law of action and reaction in mechanics of fluid is also included.
- Piskač V.: Three new experiments, Fair 12, Praha 2007
The 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.
