- Trzebuniak A.: Experimental Set with Many Questions II, Fair 10, Praha 2005
Four experiments from geometric optics; students are supposed to estimate sometimes even an unexpected result.
- Trzebuniak A.: Experimental Set with Many Questions III, Fair 11, Olomouc 2006
Utilization of experimental kits helps the teacher to prepare interesting revision lessons or optional exercises. These sets can liven up the work with students and they can lead to easier understanding and longer keeping of the acquired information.
- Trzebuniak A.: Multiple Question Experimental Set-Ups, Fair 7, Praha 2002
Two kits for student experimental work completed with problematic questions with surprising answers. The first deals with the properties of polarized light, the second with the action of force between two bodies.
- Raczkowska-Tomczak K., Trzebuniak A.: Similar but different, Fair 15, Praha 2010
This article describes twelve simple experiments in which two same or similar things show different behaviour. The description also includes the reasoning of the difference. The experiments involve electrostatics, optics, surface tension, the Archimedes Law etc.
- Trzebuniak A.: The experiment sets with many questions, Fair 12, Praha 2007
A 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.
