Harvey's experiments involved both direct dissection and physiological experiments on animals. His observations of dissected hearts showed that the valves in the heart allowed blood to flow in only one direction. Direct observation of the heartbeat of living animals showed that the ventricles contracted together, dispelling Galen's theory that blood was forced from one ventricle to the other. Dissection of the septum of the heart showed that it contained arteries and veins, not perforations. When Harvey removed the beating heart from a living animal, it continued to beat, thus acting as a pump, not a sucking organ. Harvey also used mathematical data to prove that the blood was not being consumed. Removal of the blood from human cadavers showed that the heart could hold roughly two ounces of blood. By calculating the number of heartbeats in a day and multiplying this by two ounces, he showed that the amount of blood pump far exceeded the amount that the body could possibly make. He based this figure on how much food and liquids a person could consume. To Harvey, this showed that the teaching by Galen that the blood was being consumed by the organs of the body was false. Blood had to be flowing through a 'closed circuit' instead. Even though he lacked a microscope, Harvey theorized that the arteries and veins were connected to each other by capillaries.
Yes. The next step is to try and gather enough evidence to support the hypothesis.

that would be observing the things they see and when they are gathering information they are inferring. this would be a question for a science or for science fair.
Yes, the scientific method is a systematic approach used to test hypotheses and gather empirical evidence. It involves making observations, forming a hypothesis, conducting experiments, analyzing results, and drawing conclusions. This method ensures that findings are reproducible and objective, allowing for the validation or refutation of theories. Ultimately, it is foundational for advancing scientific knowledge.
The scientific method is commonly used to gather evidence and lead to understanding in research. This method involves making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions. By following this systematic approach, researchers can ensure that their findings are based on solid evidence and sound reasoning.
scientific inquirry refers to the diverse ways in which scientists study the natural world and propose explanations based on evidence they gather

something you use to gather evidence that you cant see.
The organized and logical approaches to scientific research are called the scientific method. This method involves systematic observation, measurement, and experimentation to gather evidence and test hypotheses in order to answer questions and advance scientific knowledge.
The term "scientific method" refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather. It involves systematic observation, experimentation, and the formulation of hypotheses that can be tested.
Psychologists use the scientific method to gather empirical evidence, test hypotheses, and draw conclusions based on data. It helps ensure that their findings are reliable, valid, and replicable, contributing to the credibility and advancement of the field.
