Notes: Observations & Inferences

What is an observation? • Definition: Any information collected with the senses • Observations must be as specific as possible, not relative, so that it means the same to everyone. • -Example: – Incorrect: the burning bag smelled nasty – Correct: the burning bag smelled similar to rotten eggs

What types of observations can you make? • Quantitative – observations that involve making measurements or counting. These observations are recorded as numbers. » Example: Mr. Jones has two eyes • Qualitative – observations that use words because the event/object is not measurable » Example: Mr. Jones has blue eyes

Practice: Qualitative or Quantitative? • For each example decide if the observation is Qualitative (QL) or Quantitative (QNT). • 1. The candy was sour • 2. The snake was 2 m wide • 3. The flower is red • 4. The slug was slimy • 5. The volume was turned up to level 8 • 6. The mass of the beaker is 122 g • 7. My fingernail is 2 cm long • 8. He has 3 sisters • 9. It made a loud popping sound • 10. The surface feels rough

What is an inference? • Definition: Possible explanation for observations • The process of drawing a conclusion based on observed evidence. Practice: • Observations: • I hear people screaming • I smell cotton candy, popcorn, and hamburgers • I see a lot of people • Possible Inference = ?

Point Printout – Option 2: Rewrite notes in your own words • PICTURES and/or WORDS ARE OKAY!! (Examples on the next slide)
