Summary

Chemistry is often described as the central science because it connects and overlaps with disciplines such as biology, physics, environmental science, and geology. Understanding the foundations of chemistry is essential for grasping more advanced concepts in any scientific field. This chapter introduces the core ideas that form the basis of chemical study and sets the stage for exploring the molecular nature of matter. 
At the heart of chemistry lies the scientific method—a systematic approach used to investigate observations, solve problems, and test hypotheses. Scientists begin with observations, develop questions, propose hypotheses, and conduct experiments to collect data. The goal is to build models and theories that explain chemical behavior. This method emphasizes careful measurement, reproducibility, and logical reasoning, making it an essential tool in chemical research and discovery. 
Measurement is another cornerstone of chemistry. To communicate and compare results accurately, chemists use standardized units of measurement, primarily the International System of Units (SI). Quantities such as mass (in grams), volume (in liters), and temperature (in kelvins or degrees Celsius) are measured using precise instruments. Dimensional analysis allows scientists to convert between units and check the consistency of calculations, ensuring that equations make sense both numerically and conceptually.
