Science is defined in several meaningful ways. However, as a course in Senior High School, General Science involves the study of the natural phenomenon through a systematic approach of science: hypothesis, experiments, observation, and arriving at some logical conclusions.
General Science as a course involves the study and application of technology (ICT in general).
Depending on each school's capacity, various combinations of the elective subjects are made for students grouped into various classes. For example in some schools Geography is part of General Science electives.
