Making Observations and Inferences
Observations • Observations: We use our senses to gather information about the world around us. There are two types of observations.
Qualitative • Qualitative observation: (quality) Usually made with our senses. • Color, shape, feel, taste, sound. Examples: • Olivia is wearing a blue sweater. • The lab tabletop is smooth. • The dog’s fur is shiny.
Quantitative • Quantitative observation: (quantity) How many. Will always have a number. • Based on exact measurement. Examples: • The room is 8 meters across. • Sarah is 141 -cm tall. • Sam weighs 150 pounds.
Inferences • Inference: • A logical interpretation of an event that is based on observations and prior knowledge. What does this mean in 5 th grade science? Turn to a friend right now and talk quietly about this!
Making Inferences • You are at the counter in the office to get a bus pass signed. You see a student leave the principal’s office crying and upset. We could make an inference as to why the student is upset. • Could be in trouble (ISS, OSS, expelled) • Family problems at home (sick, accident) • Student not feeling well • Student has poor grades (failing, retention)
