- 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.
- Dvořák L.: Experiments in Malá Hraštice – this time with heat, Fair 13, Plzeň 2008
This contribution describes a simple demonstration of adiabatic process, especially the difference between adiabatic and isometric process. There is also described a set of experiments to demonstration and measurement of the heat transfer by radiation using ICT or simple cheap devices
- Dvořák L.: Physics with The Laughing Cow – or experiments with very simple equipment, Fair 10, Praha 2005
A collection of simple experiments from the field of mechanics, oscillatory motion, acoustics and optics conducted with cheese boxes.
- Dvořák L.: The “Wander Fly” Magic Wand and Czech Physics Teacher, Fair 16, Olomouc 2011
This contribution describes the utilization opportunities of “Wander Fly” wand which can come to (not only Czech) teacher’s mind. It also gives some ideas how to replace the original flying objects made from a thin foil that are easily damaged.
- Dvořák L.: Unconventional Measuring Equpiment, Fair 6, Olomouc 2001
A construction of three measuring devices. The first one measures the magnetic induction, the second is a LED voltmeter and the third represents scales consisting from a small tractor, which goes up and down a seesaw.
- Dvořák L.: Unusual measuring instruments 4: Measuring short time intervals, Fair 9, Brno 2004
Measuring of the duration of a hammer blow against an anvil by charging a condenser, mathematical analysis included.
