Which subskill best fits the process skill of observing?

The subskill that best fits the process skill of observing involves using the five senses to collect evidence and write descriptions. Observation is a fundamental aspect of the scientific method, as it entails gathering data through direct sensory experience. This can include sight, hearing, smell, touch, and taste to collect information about the environment or phenomena being studied. By employing these senses, a scientist can create detailed descriptions of what is observed, which is critical for forming a solid foundation for further analysis and experimentation.

The other options describe different scientific skills: using mathematical calculations relates to data analysis, formulating a hypothesis pertains to making predictions based on existing knowledge, and conducting experiments involves testing hypotheses under controlled conditions. While these are important scientific activities, they do not directly align with the skill of observing, which focuses on firsthand sensory experience and recording those observations.
