A laboratory experiment is a controlled procedure carried out to test a hypothesis or investigate a scientific question. It typically involves manipulating variables and observing the effects in a structured environment, such as a science lab. Researchers use various tools and equipment to gather data, ensuring that conditions remain consistent to achieve reliable results. These experiments can be conducted in various fields, including biology, chemistry, and physics. By following a systematic approach, scientists can draw conclusions based on their observations, contributing to the broader understanding of natural phenomena and advancing knowledge in their respective disciplines.
