+# Science Learning Curriculum
+
+A large collection of structured learning units covering the scientific method, physics, chemistry, biology, earth and space science, and supporting mathematics.  
+
+Content is organised by domain, topic, difficulty level (1–10), and unit type (explanation, worked example, practice problem, etc.). Each row contains a self-contained pedagogical text together with key equations, prerequisites, and an explicit learning objective.
