  1. Making Observations and Inferences

  2. Observations • Observations: We use our senses to gather information about the world around us. There are two types of observations.

  3. 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.

  4. 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 450 grams.

  5. Practice • Try the examples on your notes • 1. Sandra added 4 drops of vinegar to the backing soda • Quantitative because

  6. Inferences • Inference: • A logical interpretation of an event that is based on observations and prior knowledge. An inference explains. • You might use the word because in your inference. • What does this mean in 7th grade terms?

  7. Making Inferences • You are at the counter in the office to get a AUP to get your computer. 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)

  8. Observation VS Inferences • Observation – Based on the five senses: • Sight • Smell • Touch • Taste • Hearing • Inference – Based on prior knowledge or opinion
