The conclusion in a science project summarizes the results of the experiment and either contradicts or supports the original hypothesis. It is a simple and straightforward answer to the question posed by the experiment. This section is clear, concise and informative.Full Answer >
A falsifiable hypothesis is a proposed explanation for an event or occurrence that can be proven false. The falsifiability of a hypothesis requires that the statement can be refuted based on a scientific and observable investigation.Full Answer >
The scientific method has four major steps, which include observation, formulation of a hypothesis, use of the hypothesis for observation for new phenomena and conducting observational tests to support or disprove the hypothesis. The scientific method is primarily used to develop a representation of the world.Full Answer >
