Observation & Inference
Objectives
Content: I can demonstrate understanding of observations and inferences by identifying examples of each using a PowerPoint.
Language: I can write to identify examples of observations and inferences using “The Boy in the Water,” and write to create my own examples of observations and inferences on an Observations and Inferences handout.
Let’s number Off
• I will give you a number!!!!
• Please record the number at the top of your paper (ISN).
Observations• Any information collected with the senses.
• Quantitative – mesurable 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
• The skill of describing scientific events
Inference• Conclusions or deductions based on observations.• The process of drawing a conclusion from given
evidence.
Practice: • Observations:
• I hear people screaming• I smell cotton candy, popcorn, and hamburgers• I see a lot of people
• Inference = ?
Look at these two sets of animal tracks.
List 3 OBSERVATIONS: Use sentence Stems below
One observation I made is…
Another observation…
Last,
Make an INFERENCE: Use sentence Stem below
I infer that….
Think-Pair-Share
Remember to use scientific vocabulary:
• Observation

Homework!!!

Make an inference based on the observation below:Observation: Mrs. Giger walked into class with a frown on her face and blood-shot eyes.

Identify the statement as an observation or an inference:

Create your own example of an observation and inference:
