Simple Scientific Method Experiment Examples
Scientific method, mathematics and the experimental method used in science. In particular, it is a method used in the construction and testing of scientific hypothesis.
Independent And Dependent Variable Examples
The process of observing, asking questions, and finding answers through tests and experiments is not unique to any field of science. In fact, the scientific method is widely used in science, in many different areas. Many empirical sciences, especially the social sciences, use mathematical tools borrowed from probability theory and statistics, as well as their outgrowths such as decision theory, game theory, application theory, and operations research. Philosophers of science have addressed common methodological problems, such as the nature of scientific explanation and the justification of induction.
The scientific method is important in the development of scientific theories, which explain the rules of action (experiential) in a scientific way. In the application of the scientific method, the researcher creates a hypothesis, tests it through different methods, and then revises the hypothesis based on the results of tests and experiments. The developed hypothesis is then revised, further expanded, and repeated until it is consistent with observed events and test results. In this way, hypotheses serve as tools used by scientists to collect data. Based on the data and the many different scientific investigations conducted to investigate the hypothesis, scientists are able to develop general explanations or scientific theories. The scientific method is defined as a series of methods that people use to gather information about the world around them. They do this to improve their knowledge by getting more information and they try to explain how and why things happen. This process involves analysis, formulating questions, making assumptions, conducting analyses, analyzing data and finally drawing conclusions. The steps and definitions of the scientific method are described below:
The exact steps used in scientific methods can vary from place to place, but they are generally similar to gaining knowledge through observation and experimentation.
Observing the world is the first step in the scientific process. Before working on assumptions or finding and testing, it should be necessary to consider some events that occur.

After checking, a question should be asked based on their observation. In some cases, this step is to listen first before conducting an investigation using the scientific method. But in fact, this observation and questioning happen at the same time, because no one can look at a shocking event and immediately think “why is this happening?” Or what is it called?’. Once the analysis is done and the question is asked, the scientific method moves to the next step.
A hypothesis is a hypothesis to explain events that occur based on previous observations. Assumptions can be specific or general, depending on the question asked, but all assumptions must be tested by gathering evidence that can be measured.
After formulating the hypothesis, testing must be done. It is done in order to test the hypothesis. An experiment should have an independent variable that is used by the experimenter and a dependent variable that is measured. During the implementation of the experiment, data is collected.
Data should be analyzed after conducting the test and collecting the data. Experimental research is often analyzed with statistical software to determine relationships between data. In a simple experiment, one would look at the data and see how it correlates with changes in the independent variables.

Forming a conclusion is the final step of the scientific method. If the data supports the hypothesis, then the hypothesis can explain the phenomenon. If the data does not support the hypothesis, then more observations must be made, then a new concept will be created and all scientific methods will be used again. When a conclusion is reached, the research can be presented in order to inform others and get feedback about the validity of the research results.
Scientists have conducted many experiments using the scientific method over the centuries. Scientist Francesco Redi conducted an experiment on spontaneous generation. At 17
Century, when Reddy lived, people believed that living things arose only from organic matter. As people believed the worms came from the meat that was left behind. Reddy gives another idea that magos were the eggs of flies. He makes an attempt for this purpose by leaving four jars of meat outside, some uncovered and some covered with muslin. The flies entered the unsealed jar and after a short time; Worms appeared, while the jar was covered with visible worms on the outer surface of the muslin. Through this experiment, Reddy concludes that the worms did not come from the meat, but in fact they are the eggs of the flies.
Example of Scientific Method: The scientific method is not only used by scientists in their research, but also used by people in their daily lives. For a while, when you are at home, the light bulb goes off. First, you see that the light bulb has gone out, this is a sign. Then the question arises in your mind, “why did the light bulb go off?” and come up with possible assumptions, such as assumptions. Then, you’d do a small, predictable experiment, like replacing a light bulb. If the bulb goes back on, you conclude that the bulb is burnt out, but if the bulb still goes out, you come up with a guess and try them one by one.

Prediction: If we replace the light bulb and it gives light, my opinion will be confirmed. If the bulb does not give light, then my idea does not work.
Observations: When beans are planted in soil they grow quickly outside or inside the soil.
Null Hypothesis: There is no significant difference between growing beans indoors or outdoors.
Experiment: For this purpose, plant four beans in the same pots using the same soil. As you put two of these pots in the outer area and get two more pots in the inner area.
Citizen Science In Environmental And Ecological Sciences
Analysis: Collect and analyze the data and adjust or check how these plants grow in two locations during the three week observation period.
Conclusion: We have seen that the Bean plant is placed inside or outside the house, it produces quickly. The scientific method is a method developed in the seventeenth century by which hypotheses are made, tested, and can be proven or disproved. It is a systematic way of determining the validity of scientific theories through careful observation and experimentation.
The scientific method is used to design and conduct research. The purpose of the scientific method is to have a systematic way of testing ideas and reporting results in the scientific research process. An important aspect of the use of the scientific method is that it ensures that the experiment must be repeated by everyone. If this is not possible, then the results are considered useless.
Before you can properly use the scientific method in your experiments, you must have a good understanding of independent and dependent variables. To better understand how the scientific method works in practice, consider the following simple experiments that you can try yourself in everyday life.
How To Conduct Experiments Using The Scientific Method
In this experiment, you can choose to vary the amount of sugar added (during step 3 of the scientific method above) to see if that changes the results as well. This can be a powerful test because you will have more data to talk about.
While a single sampling during a traffic jam in one area may not be representative of the entire city, such observations can be a good starting point for further study and analysis.
A scientific approach to testing ensures that your work is well thought out and organized, and that all data is recorded and can be easily shared. This, together with the possibility of repeatability of the experimental conditions, reduces any bias on the part of the scientist conducting the experiment. Furthermore, communication of the results allows our colleagues to review the work to ensure that the results are correct, accurate and correctly interpreted. And all of these components build on STEM (or is it STEAM?) education.
