What is an observation
vagabundo [1.1K]
Hello!

Could be either:

<span>The action or process of observing something or someone carefully or in order to gain information.
</span>
Or 

<span>A remark, statement, or comment based on something one has seen, heard, or noticed.
</span>
And in Science:

 <span>An 'observation' in the scientific sense, is when you make a measurement or evaluation of some sort. You would usually make a note of how something has changed sine the previous ovbservation. Maybe the temperature has changed: gone up one degree; or a crystal has grown: maybe it is now .1 centimeters longer. 

"Observations" usually implies that you are watching some process, and either measuring or noting the change that has taken place. usually you will also want to note the time of the observation, so that you can have an idea of how quickly (or slowly) the changes are occurring.
</span>
