This guide focuses on essential observation skills, outlining the differences between qualitative and quantitative observations. Qualitative observations utilize the five senses—such as color, smell, and texture—while quantitative observations rely on measurements like mass and volume for precision. Additionally, it discusses the concept of inference, which interprets observations by using evidence rather than mere guesses. These foundational skills are crucial for scientific inquiry and should be documented in your folder or binder for future reference.

OBSERVATION • The study of an object in detail. • To observe • Carefully explore all the properties (characteristics) of an object or substance • Two types • Qualitative • Quantitative
Qualitative Observation • An observation that obtains information by using your five senses. • Color • Smell • Taste • Hardness • Texture
Quantitative Observation • An observation in which information is obtained through instruments and measurement • These are more precise (more accurate) than qualitative • Mass • Length • Volume
INFERENCE • The interpretation of an observation. It attempts to explain an observation based on evidence gathered. • Therefore, an inference is not a guess because it is based on evidence.
