How do we study these?
(how do we gather and Process
information?)
Tectonics
Use your senses to
gather information.
We use instruments
to aid our senses.

Observation
Inference
(a guess based
on observations)

3. Aim 3: How can we distinguish the difference between an observation and an inference?
Jumpstart : Record five events that you observe in your daily life 1. 2. 3. 4. 5.

4. What is an observation?
An observation is when scientists use their five senses to gather information
Example: That rock has a glassy texture

5. What is an inference?
An inference is when scientists make an educated guess BASED on observations. Example: Since the rock has a glassy texture, it was probably made right outside of a volcano

6. Turn and Talk!
Turn and talk with your neighbor to: .Create two sentences where scientists made observations about an important event AND IN THE SAME SENTENCE: What inferences did they make? Example: The scientists observed water on Mars, therefore they inferred that life could exist there!
