InferenceInferenceAn inference is a conclusion or
prediction based on something that you observe
After you make an observation, you usually make an inference about what is going on
Observation + Why = Inference
Practice: Observations:• I hear people screaming• I smell cotton candy, popcorn, and hamburgers• I see a lot of people
Inference = ?

Let’s practice making Let’s practice making inferences!inferences!
The next three slides show some fossil imprints that were found during a archeological dig. We’re going to record some observations and then make some inferences about what may have happened millions of years ago….

For each picture…
•Write down three observations-things that you can actually see that you believe are very important to the picture you are viewing.•Write down three inferences-things that you suppose are likely to happen or already happened, based on what you see in the picture.
