field journal

When "ologists" observe plants, animals, fossils, or rocks, they know they won't remember every detail. So they keep notes, called field journals. In these journals, scientists write down information about their finds: the date and time, the location, and any interesting details. Sometimes they'll make a sketch of a specimen, or note questions to research later.

What: a collection of information accumulated on an expedition
Kept by: any "ologist"
How: by using careful record-keeping skills to record all field observations
Characteristics: contains drawings, records of daily activities, maps, tickets, and any other important information from the expedition that the "ologist" can refer to when they return home
