Answer 1

Yes, you are right. A student reported that a limp stalk of celery became crisp when placed in ice water. This is an example of an observation.

Observation is the process of actively acquiring information from a source of study. When the observation is collected using the senses, it becomes an empirical evidence. However observations are also scientifically recorded using various scientific instruments for precision and accuracy. Example, use of thermometer to record the room temperature.
