Sound Wave Lab / Schallwellen-Labor
Move from quiet to loud and low to high while children see, say, and sketch simple sound-wave ideas.
1. Choose a classroom sound / Wähle ein Geräusch
Teaching note: bigger waves = louder sound; tighter waves = higher pitch. This is a child-friendly model, not a measurement tool.
