Mystery Box:
ObservationObservationAn observation is information that is
gathered through the 5 senses Smell, sight, taste, touch, hearing
2 Types of Observations Quantitative – data that can be measured or
counted 3 meters long 4 marbles 50 kilograms 35 degrees Celsius
Qualitative – data that is described using words, but cannot be measured or counted
red flowers smells like fresh baked cookies Tastes bitter
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….
What do you think What do you think happened? happened?
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.
Observation or Inference?Observation or Inference?1a. Kevin has a cast on. 1b. He must have broken his arm. 2a. Mrs. Myers loves to read. 2b. Mrs. Myers is my English teacher.3a.

1a (Observation-see it) 1b (Inference- guess b/c see
cast)
2a (Inference b/c she teaches English- or we see her with books)
2b (Observation it is a fact)
3a Inference (guess based off of evidence- she was yelling)
3b (observation fact- we heard her yell)
4a- Observation- fact we tasted it
4b inference- guess based on evidence it tasted funny we are guessing why
