THE SCIENTIFIC METHOD: STEPS & EXAMPLES Anyone can think like a scientist by using common sense and paying attention to SIX careful steps. 1. State the Problem or Question to be answered 2. Make some related Observations 3. Form a Hypothesis 4. Test the Hypothesis (figure out a way to get some evidence) 5. Get some Results 6. Make a Conclusion
Do Background Research
The scientific method has four steps
- Observation and description of a phenomenon. ...
- Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
- Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. ...
Construct a Hypothesis
The scientific method has five basic steps, plus one feedback step:
- Understand the Problem.
- Collect Information.
- Form a Hypothesis.
- Test Hypothesis.
- Keep Accurate Record.
- Check Results.
- Repeat Experiment.
- Confirm Conclusion.
Analyze Your Data and Draw a Conclusion
Step 3: State your hypothesis. Now it's time to state your hypothesis. The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and ...

What is the first step of the scientific method?
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false.
What are elements of scientific method?
It's characterized by six key elements: questions, hypotheses, experiments, observations, analyses, and conclusions. These elements are interrelated steps, so they don't always function in the same order.
What is scientific method of research?
The scientific method is the process of objectively establishing facts through testing and experimentation. The basic process involves making an observation, forming a hypothesis, making a prediction, conducting an experiment and finally analyzing the results.

scientific method. A process used by scientists to find answers to a question or to solve a problem. qualitative observation. Uses your 5 senses to describe a result (color, odor, shape, or some other physical characteristic)
What happens if an experiment is analyzed and a hypothesis is disproved?
If your hypothesis is disproved, then you can go back with the new information gained and create a new hypothesis to start the scientific process over again.
How to find evidence for an answer?
If you want to find evidence for an answer or an answer itself then you construct a hypothesis and test that hypothesis in an experiment. If the experiment works and the data is analyzed you can either prove or disprove your hypothesis.
Why do scientists go back and construct a new hypothesis?
Scientists often find that their predictions were not accurate and their hypothesis was not supported , and in such cases they will communicate the results of their experiment and then go back and construct a new hypothesis and prediction based on the information they learned during their experiment.
What is hypothesis in science?
A hypothesis is an educated guess about how things work. It is an attempt to answer your question with an explanation that can be tested. A good hypothesis allows you to then make a prediction:#N#"If _____ [I do this] _____, then _____ [this] _____ will happen."
Why is it important to conduct a fair test?
You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same.
What is iterative process?
A process like the scientific method that involves such backing up and repeating is called an iterative process. Whether you are doing a science fair project, a classroom science activity, independent research, or any other hands-on science inquiry understanding the steps of the scientific method will help you focus your scientific question ...
Why do you want to be a savvy scientist?
Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and ensure that you don't repeat mistakes from the past.
What happens if you don't do the experiment?
If it did not happen, you can create a new hypothesis and return to step four, and conduct a new experiment to prove your new theory. If what you hypothesized happened during the experimentation phase, the final step is putting together your findings and presenting them to others.
What is hypothesis in science?
A hypothesis is an educated guess that seeks to answer a question that can be systematically tested. Your hypothesis should also include your predictions that you can measure through experimentation and research.
How to test a hypothesis?
Test your hypothesis by conducting an experiment. Next, test your hypothesis by conducting an experiment. Your experiment is a way to quantifiably test your predictions and should be able to be repeated by another scientist.

Here are the seven steps of the scientific method illustrated by an example scientific ...
What is the scientific method?
The scientific method is a process used when conducting experiments and exploring observations. Some areas of science rely more heavily on this method to answer questions, as they are more easily tested than other areas. The goal of this method is to discover the relationships between cause and effect in various situations and applications.
Why do scientists use the scientific method?
Scientists also use the method to determine whether all information presented and found can combine to create a logical answer. The scientific method provides a way to apply logical and rational problem-solving methods to scientific questions.
How to make sure the results of an experiment are accurate?
If you change any factors in your experiment, keep all others the same to maintain fairness. After you complete the experiment, repeat it a few more times to make sure the results are accurate.
How to control variables in an experiment?
When you design an experiment, you are controlling and measuring variables. There are three types of variables: 1 Controlled Variables: You can have as many controlled variables as you like. These are parts of the experiment that you try to keep constant throughout an experiment so that they won't interfere with your test. Writing down controlled variables is a good idea because it helps make your experiment reproducible, which is important in science! If you have trouble duplicating results from one experiment to another, there may be a controlled variable that you missed. 2 Independent Variable: This is the variable you control. 3 Dependent Variable: This is the variable you measure. It is called the dependent variable because it depends on the independent variable.
Why is it important to write down controlled variables?
Writing down controlled variables is a good idea because it helps make your experiment reproducible, which is important in science! If you have trouble duplicating results from one experiment to another, there may be a controlled variable that you missed. Independent Variable: This is the variable you control.
How many steps are there in the scientific method?
Sometimes the scientific method is taught with seven steps instead of six. In this model, the first step of the scientific method is to make observations. Really, even if you don't make observations formally, you think about prior experiences with a subject in order to ask a question or solve a problem.
What is the scientific method?
The scientific method is a systematic way of learning about the world around us and answering questions. The key difference between the scientific method and other ways of acquiring knowledge are forming a hypothesis and then testing it with an experiment.
What is a hypothesis in science?
Alternatively, it may describe the relationship between two phenomena. One type of hypothesis is the null hypothesis or the no-difference hypothesis.
How to check references in an article?
Even if you can't access the full text of a published article, you can usually view the abstract to see the summary of other experiments. Interview experts on a topic. The more you know about a subject, the easier it will be to conduct your investigation.
Can you repeat an experiment?
Sometimes repeating an experiment may give a different result. In other cases, a hypothesis may predict an outcome, yet you might draw an incorrect conclusion. Communicate your results. The results may be compiled into a lab report or formally submitted as a paper.
What is scientific investigation?
Scientific investigations are carried out to answer a question based on observations – who, what, when, where, how. Sometimes that question is seeking a solution to a problem. The first step in the scientific process is for the investigator to frame the problem to be solved or ask a question that lacks an answer in a way that is falsifiable. ...
What is hypothesis based on?
Based on current knowledge, previous solutions and current practice, a hypothesis is proposed that can be tested as true or false, yes or no. The potential answer to the question is stated in a way that allows for a single answer in order to determine if the hypothesis is correct.
What happens when a hypothesis is false?
If the hypothesis is true, then the question is answered. If the hypothesis is false, what was learned is integrated and a new hypothesis formed, including subsequent experiments and observation.
How many steps are there in the scientific method?
The scientific method is a five- step process used in scientific investigation. Sometimes the steps are combined or added to, but the five are the basic structure for any endeavor to answer a question objectively.
Why are experiments repeated multiple times?
The experiments are repeated multiple times to ensure the results are credible and to account for human error and contamination. Multiple conditions and variables are often tested as well.
What is fair test?
By changing a single variable at a time, a fair test is conducted that provides objective results about the effect of that specific variable in relation to the controlled conditions.
