4. Inference • An 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 = ?

5. Let’s practice making 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….

8. What do you think happened?

9. 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.
