This document outlines the grade 7 science curriculum for the school year divided into 4 quarters. It includes 27 key learning competencies to be covered, the number of days spent teaching each competency, and the essential concepts to be learned in each area. The focus is on scientific investigation, properties of matter, cells, reproduction, ecosystems, waves, sound, light, heat transfer, electricity, Earth systems, weather, seasons and eclipses.
