Interactive Physics Laboratory

Welcome to the website of the Interactive Physics Laboratory (IPL, the Czech abbreviation IFL), which is managed by the Department of Physics Education, Faculty of Mathematics and Physics, Charles University in Prague.

The IPL is a place where we enable high school students to grasp physics with their own hands. We do not offer a show, we prepare conditions for students’ own experimenting in physics.

About the project


The birth of the laboratory

The idea to establish a laboratory intended primarily for high school students at the Faculty of Mathematics and Physics was inspired by the House of Science in Stockholm, which – unlike IPL – focuses on not only physics experiments, but experimenting in science generally. With the support of the Faculty, the laboratory was opened in December 2008.

Our goals

The goal of the IPL is to provide high school students (resp. their teachers) a space for conducting physics experiments which could be hardly carried out in the classroom because of their time or equipment demands. Students play a major role – they conduct all the experiments with their own hands, prepare measurements, record and evaluate data and at the end briefly present their results to their classmates. For the whole time in the laboratory, students can consult their steps with lecturers, whose role is however only supportive – students are led to maximal autonomy. We believe this way we can help students to significantly deepen their physics insight as well as manual skills.

Basic information for teachers intending to visit IPL

What does the typical visit of the IPL look like?

How to reach the IPL?

The IPL is situated in the campus of Faculty of Mathematics and Physics in Praha-Trója (street V Holešovičkách 2), the building of Heavy Technology Laboratories, 2nd floor, door L261.

Transportation to the campus is from the subway station Nádraží Holešovice (line "C") with bus no. 201 to the stop Kuchyňka or with bus no. 112 to the stop Pelc Tyrolka. The walk from both these stops to the IPL is shown in the picture below.
