  1. Scientific Observations and Inferences

  2. Observations • Any information collected with the senses. • The skill of describing scientific events QUANTITATIVE • Measureable or Countable • 3 meters long • 4 marbles • 50 kilograms • 35 degrees Celsius QUALITATIVE • Describable, Not Measureable • red flowers • smells like fresh baked cookies • Tastes bitter

  3. Inference • Conclusions or deductions based on observations. • The process of drawing a conclusion from given evidence.

  4. Learning Goal Students will be able to make correct scientific observations and scientific inferences .

  5. Let’s PracticeClose your eyes… • Observations: • I hear people screaming • I taste cotton candy • I smell popcorn, and hamburgers • I see a lot of people • I feel grass under my feet • Inference = ?

  6. Fill in the blanks with one of the following words: OBSERVATIONS INFERENCE One of the most important skills in science is the use of our five senses, to make ____________________.
