The primary purpose of an experiment is to investigate a hypothesis or research question through controlled observation and manipulation of variables. Experiments aim to gather evidence that supports or refutes a specific idea about how something works or to explore a "what-if" scenario. Ultimately, experiments contribute to the expansion of scientific knowledge and understanding of the world. Here's a more detailed breakdown:Testing Hypotheses:Experiments are designed to test the validity of a hypothesis, which is a testable prediction about the relationship between variables. Exploring Cause and Effect:By manipulating variables and observing the outcomes, experiments help establish cause-and-effect relationships between different factors. Gathering Evidence:The data collected during an experiment provides evidence that can be used to either support or refute the initial hypothesis. Building Scientific Knowledge:The results of experiments contribute to the broader body of scientific knowledge, helping us understand how things work and interact. Answering "What-If" Questions:Experiments can also be used to explore new phenomena or test unexpected ideas, even without a specific hypothesis in mind.
