This document discusses the correlation between physical science and other subjects like mathematics, biology, and languages. It explains how physical science is related to these subjects and provides examples. Physical science relies on mathematics through its use of algebraic equations, geometry, and graphs. Biology also correlates with physical science through topics like respiration, photosynthesis, and food absorption which can be explained by physics and chemistry. Languages are important for physical science students to clearly express scientific ideas and principles. The document concludes that correlating subjects helps students make connections between different areas of knowledge and improves their understanding and interest in learning.
