What do we mean by that?
Let us give an example:
We mean that Munch’s famous painting “The Scream” can be a starting point for talking / learning / experimenting / playing and discussing sound waves, as the central image of the painting expresses a strong dramatic cry (see case study in stemproject .eu -> Case studies -> Science -> sound waves and “the scream” of Edward Munch). Thus, Edward Munch’s painting, while from an artistic perspective expresses strong feelings of despair and hopelessness. However, if we observe it through the lens of science, it becomes an object of analysis, examination and knowledge, where we notice wavy forms which resemble sound waves of low or high frequency.
