A black-box is a kind of<br \/>\nexperimental task where the inner structure is not visible to the experimenter. Using mirrors,<br \/>\nbeam-splitters, and blockers in a black-box to manipulate the light beam\u2019s direction through this<br \/>\nspecific experiment, students are instructed to vary input and observe the output of light to get an<br \/>\nidea of the possible inner structure. The presented sequence of black-box experiments requires a<br \/>\nbasic knowledge of the linear propagation of light and is suitable for beginner physics. Furthermore<br \/>\na framework for concrete implementation to physics classes is given, which covers suitable structure<br \/>\nof class, examples for helpful worksheets, and authentic students\u2019 solutions.
