- 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.
- Jakubičková J., Klinovská L.: Other ideas from Malá Hraštice: magnets’ repulsion, Fair 24, Hradec Králové 2019
The paper describes in detail the manufacturing process of making a speaker. In the second part, the possibilities of incorporating the speaker activity into the classroom are proposed.
- 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.
- Kundracik F.: The mystery of pipe acoustics, Fair 18, Hradec Králové 2013
The paper provides information on the basic principles of the formation of tones in pipes and their tuning. It also presents some ideas for making simple pipes.
- Mandíková D., Drozd Z.: Bits and pieces from an acoustic workshop, Fair 23, České Budějovice 2018
The paper presents selected experiments from the acoustic workshop. Description of an experiment includes detailed execution instructions and methodical notes.
- 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.
- Reichl J., Dvořák J.: Ruben’s tube, Fair 23, České Budějovice 2018
The paper describes construction of a device that is suitable for demonstration of gas compressibility by acoustic waves, demonstration of standing waves, sound propagation in gas, … The device originated on basis of a gifted student Jakub Dvořák’s preparation for practical physics homework.
