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.

4a- Observation- fact we tasted it

4b inference- guess based on evidence it tasted funny we are guessing why
