A suggested and testable explanation for an event is known as a hypothesis. This foundational concept in the scientific method allows researchers to formulate predictions that can be tested through experimentation or observation, paving the way for discoveries and advancements across various fields of science. In practice, crafting a strong hypothesis involves formulating a clear, specific, and measurable statement that predicts an outcome based on initial observations. Common mistakes include making hypotheses too vague or basing them solely on opinions without scientific backing. Remember, a good hypothesis is rooted in prior knowledge and leads to exciting explorations!
