Observations and Inferences

Two Tools Every Scientist Needs

Charlottesville City Schools

October, 2005


Observation

Observation

  • An observation is a fact learned “directly” through the senses.

    • Sight, touch, smell, taste, and hearing

  • Observations are personal experiences since they are influenced by your past experiences.

  • The more we observe, the more we learn.


Inferences

Inferences

  • Inferences are conclusions and explanations about events that are not directly observed.

    • Inferences are based on observations.

    • Scientists often make more than one inference to explain an observation.

    • New observations can either support or negate inferences.


Let s make an observation

Let’s make an observation

  • You will have 30 seconds to observe the next slide.

  • After you have looked at the slide, write down your observations on your worksheet.

    • Use as many details as possible

    • Work quickly…you will have I minute to complete all of your observations.

  • Ready?

  • Let’s begin!


Time is up

Time is up!!!

Let’s share our observations, but be an active listener…don’t repeat what was already stated.


Now let s make an inference

Now, let’s make an inference.

  • Using your observations, what sounds do you think you would hear if you were looking at the actual scene, not a picture of this scene?

  • Let’s make another observation of this scene.


Observations and inferences

Did your second observation cause you to change your thoughts about what you inferred you might hear?

If you want to modify your inference, change it now.


Let s make another observation

Let’s make another observation.


Do you still think you will hear the same sounds

Do you still think you will hear the same sounds?

Let’s make another observation.


How about now change your inference now if you want

How about now? Change your inference now if you want.

Let’s make one last observation…


What inferences can you make about the setting

What inferences can you make about the setting?


Now let s look at something else what do you see

Now let’s look at something else…what do you see?


Let s look at something else

Let’s look at something else…


Look at the following figure

Look at the following figure.


Now look at the next figure

Now look at the next figure.
