Don't worry, it isn't that complicated. Let's take a closer look at each one of these steps. Then you can understand the tools scientists evernote use for their science experiments, and use them for your own. Observation, this step could also be called "research." It is the first stage in understanding the problem. After you decide on topic, and narrow it down to a specific question, you will need to research everything that you can find about. You can collect information from your own experiences, books, the internet, or even smaller "unofficial" experiments. Let's continue the example of a science fair idea about tomatoes in the garden. You like to garden, and notice that some tomatoes are bigger than others and wonder why.
If your experiment isn't designed well, you may not get the correct answer. You may not even get any definitive answer at all! The Scientific Method is a logical and rational order of steps by which scientists come to conclusions about the world around them. The Scientific Method helps to organize thoughts and procedures so that scientists can be confident in the answers they find. Observation writing is first step, so that you know how you want to go about your research. Hypothesis is the answer you think you'll find. Prediction is your specific belief about the scientific idea: If my hypothesis is true, then I predict we will discover this. Experiment is the tool that you invent to answer the question, and. Conclusion is the answer that the experiment gives.

The Scientific Method is a process used to design and perform experiments. It's important to minimize experimental errors and bias, and increase confidence in the accuracy of your results. In the previous sections, we talked about how to pick a good topic and specific question to investigate. Now we will discuss how to carry out your investigation. Steps of the Scientific Method, now that you have settled on the question you want to ask, it's time to use the Scientific Method to design an experiment to answer that question.

Scientific method in Culture, an orderly technique of investigation that is supposed to account for scientific progress. The method consists of the following steps: (1) Careful observations of nature. Deduction of natural laws. (3) Formation of hypotheses — generalizations of those laws to previously unobserved phenomena. (4) Experimental or observational testing of the validity of the predictions thus made. Actually, scientific discoveries rarely occur in this idealized, wholly rational, and orderly fashion.
A theory is a set of statements, including laws and hypotheses, that explains a group of observations or phenomena in terms of those laws and hypotheses. A theory thus accounts for a wider variety of events than a law does. Broad acceptance of a theory comes when it has been tested repeatedly on new data and been used to make accurate predictions. Although a theory generally contains hypotheses that are still open to revision, sometimes it is hard to know where the hypothesis ends and the law or theory begins. Albert Einstein's theory of relativity, for example, consists of statements that were originally considered to be hypotheses (and daring at that). But all the hypotheses of relativity have now achieved the authority of scientific laws, and Einstein's theory has supplanted Newton's laws of motion.
In some cases, such as the germ theory of infectious disease, a theory becomes so completely accepted, it stops being referred to as a theory. The American Heritage Science dictionary copyright 2011.

A hypothesis is a proposition that attempts to explain a set of facts in a unified way. It generally forms the resume basis of experiments designed to establish its plausibility. Simplicity, elegance, and consistency with previously established hypotheses or laws are also major factors in determining the acceptance of a hypothesis. Though a hypothesis can never be proven true (in fact, plan hypotheses generally leave some facts unexplained it can sometimes be verified beyond reasonable doubt in the context of a particular theoretical approach. A scientific law is a hypothesis that is assumed to be universally true. A law has good predictive power, allowing a scientist (or engineer) to model a physical system and predict what will happen under various conditions. New hypotheses inconsistent with well-established laws are generally rejected, barring major changes to the approach. An example is the law of conservation of energy, which was firmly established but had to be qualified with the revolutionary advent of quantum mechanics and the uncertainty principle.
