Observation and Inference 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.
