-Explain why observations are important
- Write detailed observations -Make inferences
Today I will be able to…
Key Point 1: An observation is
• Gathering and collecting information (data) using your five senses and tools– Sight– Touch– Hear– Smell– Ruler– thermometer
• Ex: I taste that chocolate is sweet
Key Point 2:An inference
is an interpretation of your observationsEx: I think this is a snickers because it tastes like chocolate and peanuts
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.
“Beyonce looksgood”
• Not an observation!!!– It is 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.
Observation or Inference? Part I
• This kid looks like a dork.
• The cowboy hat is brown.
• Cake tastes delicious.
• The bandana is red.
• I believe it is his birthday.
Partner Up
• Partners take turns answering
• Classify and explain why
• If your partner doesn’t explain why, ask them!
• If you disagree, you may ask your group
• If the whole group disagrees, all raise hands
Observation or Inference? Part I
