All science involves observations. A scientist is either observing the world as it is normally, or is changing something and observing the results of the change. The "change something and observe the results of the change" is called an "experiment".
If you're not observing something, then you are not doing "science".

Scientific investigations that involve making observations typically include descriptive studies, field studies, and experiments where data is collected through sensory experiences. These investigations often focus on gathering qualitative or quantitative data to understand phenomena, identify patterns, or test hypotheses. Observations can be made in various contexts, such as ecological surveys, behavioral studies, and laboratory experiments. Overall, observation is a fundamental aspect of the scientific method that aids in forming conclusions and generating further questions.

One that predicts an outcome.
Using a balance to measure mass might be part of a scientific investigation, but by itself and under ordinary circumstances it does not amount to a scientific investigation. If you are on a different planet or on a moon, or if you were in the weightlessness of space, then doing this (or trying to do it) might be considered a kind of investigation.
