What term describes a procedure carried out to discover unknown effects or illustrate known laws?

The term that describes a procedure specifically designed to discover unknown effects or illustrate known laws is "experiment." An experiment is a structured and methodical approach to testing hypotheses and gathering data to draw conclusions about a particular phenomenon. It often involves manipulating variables and observing the outcomes, allowing for the identification of relationships and effects that may not be apparent through mere observation or analysis.

In scientific contexts, experiments are crucial as they provide controlled environments where variables can be isolated and tested rigorously. This allows researchers to validate theories or uncover new insights based on empirical evidence. The emphasis on experimentation underscores its role in the scientific method, facilitating advancements in knowledge and understanding across various fields, including cosmetology.

Investigation, while related, refers to the broader process of examining or inquiring into a subject and could include experiments as part of its methodology. Analysis typically involves the examination of data or information after it has been gathered, rather than the process of discovering new effects. Observation refers to the act of watching or noticing something, which does not entail the systematic approach that experimentation involves.
