The generic, cross-cutting practical strand: general measurement, units, error, data handling and graphical analysis that are not tied to one topic. This is the "methods home" for lab skills applied across all topics. Topic-specific experiments (measuring g, specific heat capacity, resistivity, focal length, etc.) are NOT here, they live under their subject strand (see Design decisions).
