Homeschool Chemistry Vocabulary Chapter 1

Chemistry Vocabulary Study Notes

• Matter: Anything that has mass and occupies space, fundamental to understanding chemical concepts.

• Chemistry: The branch of science focused on the composition, structure, properties, and changes of matter.

• Organic Chemistry: Specializes in studying compounds that contain carbon, integral in pharmaceuticals and biological applications.

• Inorganic Chemistry: Focuses on substances generally lacking carbon, including metals, minerals, and organometallic compounds.

• Biochemistry: Examines the chemical processes and substances occurring within living organisms, bridging biology and chemistry.

• Analytical Chemistry: Concerned with the composition of materials, using techniques to determine quantitative and qualitative properties.

• Physical Chemistry: Investigates the physical principles underlying chemical interactions, including energy transfer and reaction mechanisms.

• Pure Chemistry: Engages in the pursuit of chemical knowledge purely for intellectual curiosity, without immediate practical application.

• Applied Chemistry: Directs research towards practical goals, often used to solve specific problems or develop new technologies.

• Technology: Refers to the tools and methods developed by society to fulfill needs and desires, closely linked to advancements in chemistry.

• Macroscopic: Refers to objects or phenomena large enough to observe without aid; critical for initial chemical observations and experiments.

• Microscopic: Describes entities that require magnification to view, essential for understanding molecular structures and reactions.

• Biotechnology: Integrates scientific principles with biological processes to create products and technologies that improve quality of life.

• Pollutant: Harmful materials present in the environment (air, water, soil) that pose risks to health and ecosystems.

• Scientific Method: Systematic approach for investigating phenomena, involving observation, hypothesis formulation, experimentation, and theory development.

• Observation: Involves gathering data using the senses, often requiring measurements for accuracy and reproducibility in scientific inquiry.

• Hypothesis: A tentative explanation proposed for observations, forming a basis for further investigation and experimentation.

• Experiment: A structured procedure designed to test a hypothesis; must be repeatable to validate findings.

• Manipulated Variable: The independent variable in an experiment that is altered to observe its effects on the responding variable.

• Responding Variable: The dependent variable that is measured and observed in response to changes made in the manipulated variable.

• Theory: A well-supported explanation that encompasses a broad range of observations, gained through extensive experimental evidence.

• Scientific Law: A concise statement summarizing consistent results from multiple observations and experiments, often expressed mathematically.
