Observations are a key part of any research or investigation. They involve the careful recording of data, information, and other details that can be used to draw conclusions. The term 'observations' can refer to a variety of different activities, including making MARKS, taking NOTES, finding evidence, and making remarks. MARKS refer to physical markings made on an object or surface, such as a graph or chart. NOTES refer to written records of observations, such as a journal entry or field NOTES. FINDINGS refer to the results of an investigation, such as the discovery of a new species or the uncovering of a hidden truth. Espials refer to the act of spying or gathering information covertly. Finally, remarks refer to verbal comments made about an observation, such as a comment made by a scientist about a specimen.
