   Objectives
    SWBAT     differentiate between
        observations and inferences

   Catalyst
     What is the class Big Goal?
     What is the proper procedure for
     walking in the class?
Always talkin’ ‘bout what you got…

 Look at the beakers on my desk.
 In groups, you have 5 minutes to

  write down as many statements
  about them as you can.
Observation

   Key Point #1: An observation is gathering
    information about the world through our
    five senses
     Examples:
      I  see that Mr. Jhaveri’s eyes are bloodshot
       I hear that the music is loud
       I smell that poo is stinky
       I taste that chocolate is sweet
       I feel that ice is cold when I touch it
Inference
   Key Point #2: An inference is a belief made about an
    observation
     Examples
       I see that Mr. Jhaveri’s eyes are bloodshot. I infer that
        he did not sleep much last night
       I hear that the music is loud. My parents probably want
        me to turn it down
       I smell that poo is stinky. So I bet that I should not rub it
        on my body
       Mr. Jhaveri should give chocolate to students as a
        reward, because chocolate tastes sweet.
       I feel that ice is cold. So I believe that it will cool down
        my cold drink
The Difference

 Key Point #3: Observations are facts,
  and can’t be wrong. Inferences are
  beliefs, and can be wrong.
 Example:

    Michael  leaves the movie theatre, and
     sees that the ground is wet. So Michael
     thinks that it rained.       Observation: Andrew
Inference: explains the            knows this by his
observation. But could there be    sense of sight. Can’t
any other reasons???               be wrong.
“Beyonce looks good”
   Not an observation!!!
     Itis not a fact that
      Beyonce looks good.
     Some people disagree.
   This is an inference!!!
     Whoever    said this
      believes that Beyonce is
      attractive because of facts:
      she has clear skin, shiny
      hair, an hourglass figure,
      etc.
Back it up like a pick-up truck

 Go back to your beaker sheet.
 Fold a new piece of paper in half. Sort the
  statements into observations on the left and
  inferences on the right
     One  sheet per person
     Do this on your own
   Can I get some volunteers
    to share their observations
    and inferences?
