  The educational use of video and multimedia is increasing rapidly in
secondary and higher education across all disciplines. Videos for physics
education can be found in many universities and other educational institutions
websites all over the world. In the area of experimental physics, the available
videos demonstrate mainly physical phenomena or physics experiments and only
few of them allow for the quantitative estimation of physical parameters. In
this work, we present characteristic videos of an ongoing project aiming at the
development of a collection of educational videos that guide students to
measure data and to analyze them in order to calculate physical quantities.
These videos can be used for physics teaching, as a demonstration, as a
supplementary educational tool for the students pre lab preparation and also in
the physics lab, if the necessary equipment is not available or in case of time
consuming measurements. The pilot use of a video related to the measurement of
the lead attenuation coefficient in the lab is presented accompanied by the
student assessment. The students favor the use of video mainly as a
supplementary tool for their pre lab preparation and not as a substitute of the
real experiment.
