Experiments have been part of the physics education for a very long time. However, in the last two decades their effectiveness as tool for teaching the students scientific concepts has been questioned.
Aim of this contribution is to compile current prevailing opinions on what goals can be achieved by including experiments in physics lessons. Furthermore, we designed a questionnaire for high school students which should evaluate what they remember from the experiments they saw during physics lessons.
This questionnaire is right now going through its pilot phase.
