Learn More about the Use of Scientific Method in Psychology

How is scientific method in psychology applied? Psychologists usually explain any human behavior using subjective and anecdotal judgments, but by using scientific method they can explain the cases in an objective and systematic way. You can learn about the definition, characteristics, and steps of scientific method to understand how the researchers come to conclusions about human behavior.

What is Scientific Method?



The scientific method is the process to investigate, acquire, and expand our understanding logically on a problem. In the process, there is a step-by-step process from the beginning until the end. When you put those steps together, you will get a sense of the answer. You should follow the step right from the number one until the end consecutively. If you start from three before two, you will more than likely to get the wrong analytical answer.


Psychological studies are trying to describe, explain, predict, and influence behaviors or mental processes of human. By utilizing the scientific method in psychology, psychologists want to conduct a psychological research in an objective and systematic way. For the result, they are expecting for able to describe and explain why the behaviors occur. Later, it can be used to create research for predicting and changing those behaviors to be in better stage.



Steps of Scientific Method


Step 1. Observation and Form a Hypothesis

First, researchers should begin with choosing a case study or a topic to study. Then, they need to conduct a review of the subject thoroughly based on existing literature. Through this review, researchers can provide valuable information that has been learned and what is the remaining question need to be answered.


After identifying the problem, researchers can formulate a testable hypothesis about the relationship between two or more variables. In this step, researchers should design the experiment using those dependent and independent variables.


Step 2. Performing Experiment and Collecting Data

There are two methods of performing experiment including descriptive and experimental research methods. Experimental methods use a demonstration of casual relationship between variables. Meanwhile descriptive methods include case studies, surveys, and observation that can’t be done through experimental. Once the experiment has been conducted, the researchers need to collect the data.

Step 3. Draw a Conclusion

After the data have been collected, researchers start to analyze and carefully examine the existing information to draw a conclusion supporting their original hypothesis.


Step 4. Reporting the Result

Once the conclusion has been drawn, the last step is sharing and reporting the result to the scientific community. The announced result will help to improve overall knowledge bases and the base for future research.



Using scientific method above, researchers can prove that psychology is also a science that has the same academic standing like biology, physic, chemistry, etc. Therefore, scientific method in psychology has been contributed to analysis several human actions, intentions and motivations on daily basis.

Scientific Method Science Fair Projects Guides

During your school days, you might have experienced scientific method science fair projects. You should have known that science project can be done by everyone, not only the scientists or experts in the specific fields. Even in our daily life, everyone has been conduct a simple scientific method unknowingly like when your TV won’t turn on you check it and find that the cord is unplugged.



Understanding Scientific Method



The scientific method is a backbone of every science experiment. It’s a tool that helps researchers to answer a question and solve the problem in objective and systematic format. The scientific methods include a logically step-by-step process to investigate, acquire, and develop our understanding on the problem. The researchers should follow the steps from the very beginning to the end consecutively to get the best answer.


Conduct Your Science Projects

Scientific Method Science Fair Projects


On starting your science project, you should follow the steps of scientific method, including:

1. Identify the problem

For example, you want to watch TV but the TV doesn’t turn on when you press the button. Here, you had identified the problem that there is a problem with your TV.


2. Observe the problem

Next, you need to collect some information regarding the problem that will support solving the problem. For example, it is the first time your TV has this problem. Before your use the TV, your brother turns it on but there is no problem.


3. Formulate a hypothesis

Hypothesis is a base of scientific project. It is an educated guess or prediction based on two or more variables (independent and dependent variable). When the TV is off, you start guessing maybe the problem is from internal or external. If it’s from internal, maybe there is a crack in the motherboard or others. But if it’s from external, maybe the problem is the cord or electricity.


4. Conduct the experiment

There are 2 methods of conducting research including experimental method by using demonstration of experiment and descriptive method by using case studies, survey, or observation. You start to check the TV. You will start from external and find that the cord is unplugged.


5. Draw a conclusion

After the observations, you draw a conclusion that your TV is off because the cord is unplugged, not because the internal problem.



Joining Science Fair Projects


When your get the answer, you can decide to join scientific method science fair projects. What you should do is preparing how to display your project so others can see your science project. Along with the presentation, you can prepare the display with description, photos, and other support tools.

Actually, there will always questions come up as long as human still exists. While there are still questions need to be answered, then scientific method will always be used. That’s why everyone can be a researcher and join any scientific method science fair projects.

Scientific Method Definition According To the True Meaning

We often know the various terms associated with the science. Some terms are now being discussed by the public is the scientific method. The word is widely known since many students do field work in the community. Then what the real scientific method definition?


Scientific method implies a process of solving a problem by using a systematic, empirical and well controlled system. As for solving the problem in a systematic understanding is that any problems will be solved with the scientific method must follow the order given. Errors in the leapfrog stages will result unscientific solution. In determining the empirical method must also mean that any results obtained must go through the stages of accurate data. The availability of evidence in the form of data makes the solution is said to be the result of research. Control must be done in order to keep the results of the research from error.



How a scientific method results can be obtained? Of course it would need the steps that must be passed one by one. Sequence step is to formulate the problem, formulate hypotheses, collect data, test hypotheses, and the last is the formulation of conclusions. All these sequences must be done properly and seriously so that the results obtained can be justified.

Scientific Method Definition



The formulation of the problem

If now you are going to do a study, then the first step is to formulate the problem to be raised. You can start with a question, for example "How far the influence of television viewing on children liveliness to learn?" Is certainly a simple thing can be made formulation. It is to train your mindset to be more open to resolve any problems.


The formulation of hypotheses

After a formulation of the problem, then the order to do next is to formulate a hypothesis about the issue. The hypothesis usually is of the opinion in some quarters, or it could be from your opinion. The hypothesis is a temporary answer to the problems to be faced. So, you can take the next step to complete the stage in the use of the scientific method.


Collect data

To solve the problem and to prove the hypotheses you must do data collection that supports your experiment. Usually for an agency, it takes some people to collect data to support the desired results. But you can also collect the data by your own. Although it’s taking a long time and lot cost depend to the broad scope on the issues that you take. But you can limit the time of data collection according to agreement, so the data can be collected on time with the experimental schedule. 


Hypothesis testing

After going through all the steps above, now is the time to test the hypothesis. Now is the time for the data to be processed. If your experiment is qualitative, the data processing is not overly involving complicated formulas. But different if your experiment quantitative, it will be valid otherwise. In qualitative experiments with only comparing data alone, you can get the results that can be accountable.


The formulation of conclusions

After seeing the results of data processing, time for you to explain the results of your experiment. In qualitative research, an explanation of the data that has been processed to be more detailed. The explanation would be better if accompanied with pictures, graphs and diagrams, not just words. Then pull the conclusions that can summarize all the results of these studies, suggested using simple words, short and dense in drawing conclusions. So by simply reading the conclusion that you pull, the reader has to understand the aims and benefits of your research.



So that we can say to you about the scientific method definition and it’s stages, may be useful to you in your experiment or in completing your coursework.

Science activities for kids directs the activity of the kids on the positive things

Science activities for kids - The child's motor is very active compared to adults. Children will be difficult if told to be quiet. They will play any item that is around; even they tend to damage or unload these items. We as adults should be able to get around this. Make liveliness of the child leads to positive things, one of them with engaging them with science activities for kids


If you involve your child on science activities for kids it is guaranteed that your kids will have learned skills that would serve him well in the present and in the future. Those skills including their ability to solve problems with scientific measures, able to concentrate on solving the problem of tolerating or even add to the problem could be individuals who inspire new ideas rather than behaving as a copyist, and others.



Compare with children who were never introduced to the science activities for kids, when they are confronted with a problem they will focus on how difficult the problem. Instead of looking for a solution, they will be lamenting the problem. They are not able to think logically and systematically. They will choose a short and instant way to resolve the problem. Though it may be the instant way requires substantial costs or contains other risks in the future. Here an example of science activities for kids which can be used as reference by you.


How do I determine the volume of irregular objects?

Science activities for kids

 


First Kids in excitatory to determine the volume of a cube. We know that in order to determine the volume of a cube we just measure the length of one side and then multiply it three times. The second step is to get the kids to determine the volume of the beam. In determining the volume of the beam we stayed measure the length, width and height then all multiplied. Now the kids are faced with a stone of irregular shape. How do the kids determine the volume of the rock? The kids will find it difficult to measure the length, width and height of the stone because of its shape. 



Provide a measuring cup and water. Bring the kids to use the tools and materials to measure the volume of the rock. Most likely the kids will be confused how to measure the volume of the rock using a measuring cup and water. Let the kids do trial and error for a while. See how creative them, may be among the kids there who could solve the problem. But solved or not by the kids, you should still give them a reward for their hard work in terms of want to try.



To measure the volume of irregular shaped objects, first pour water into a measuring cup. Record the initial volume of water. Then enter the irregular object, in this case a stone into a measuring cup that had been filled with water. Record the final volume indicated by the water in a measuring cup. Then the volume of the object is equal to the final volume minus the initial volume. It is based on the knowledge that if an object is immersed in water, the volume of the object is equal to the volume of water displaced by the object.

Thus the example of science activities for kids, hopefully it can direct the activity of the kids to the positive things.

The steps of Scientific Method Examples

Scientific Method Examples  - Every life will always be no such thing as a problem. Not least to yourself. In order to assess a problem will require a method that can provide real solutions to these problems. One method that can be applied to it is the scientific method. A lot of scientific method examples haven in your neighborhood. Diverse problems from the smallest to the largest could be made into a study to apply the scientific method.

Scientific Method Examples


•    Determine the research problem


To enable you to specify a formulation of the problem, you can create a question that has become a big question to yourself. Examples that can be used as a formulation of the problem is the effect of income on the purchase cost of daily necessities, can also be related to the process of educating young children that affect children in the growth rate. The entire real problem is that often you see, but you'd never thought of before. Knowing this method, will be a great benefit.


•    Formulate the hypothesis

Scientific method previously described examples then made the hypothesis formulation, the point for determining the initial response to the problem. Everyone has their own opinion and it cannot be verified. The hypothesis formulation can make by your own or if you have trouble stringing words, you can ask for help on your friend.


•    The gathering of data

At this stage energy and the power of your mind is needed to examine the results of which appear every day. You can collect some studies that have been a source of regular and natural, see bout few days every habit that happens in the community. To the beginning, you can choose only one study materials that energy and your mind can focus on one issue. Writing becomes very important at this stage so that accuracy in writing the information you need to prioritize.


•    Hypothesis testing

When you have observed differences in habits or anything that applies to a community, the last step you can do is a hypothesis test. The aim is to found out which hypothesis could be accepted by the audience in accordance with the existing reality. Processing of data will indicate whether the results of the hypothesis are accepted or not. This hypothesis testing can be done at one time or can be more than once. For more convincing the results, you can do the test twice.


•    Formulate a conclusion

When hypothesis testing has been done, even retest was already completed now you can make a conclusion. To strengthen the conclusion you can added the explanation of relevant data that you have processed. But remember this conclusion sentence should not be convoluted, just straight to the point, so that the reader should not be confused with your sentence.


The scientific method examples can be different on different issues this depends also on the type of research that you take. But an outline of the steps are almost the same, i.e. starting from the formulation of the research problem, making hypothesis, data collect the data, data testing and final conclusion. Hopefully this information may be useful for you.

Science Project Ideas for Kids

Making Rocket That Could Slide Into Space One of Science Project Ideas for Kids

Science Project Ideas for Kids | Childhood is a time of much pleasure and joy. Kids are often difficult if told to learn. So we as adults need to be smart to get around to the subject matter to be interesting and fun. Kids should be involved in learning rather than just listening. If kids are involved in learning it will be a lot of fun are obtained and knowledge gained will be long remembered. One of science project ideas for kids is to make rocket that could slide into space. What tools and materials are required? And how the work steps of the project? Follow the explanation below:

Making miniature of volcanoes that can erupt :

    Tools and materials

-    Redoxon packaging bottles that has been empty
-    Liquid vinegar
-    Baking soda, and
-    Wipes

    The work step

This project is better done in the open field. Input the liquid vinegar into the Redoxon bottle. Spread the tissue paper on the surface of the mouth of the bottle. Put a little baking soda on the tissue paper. Closed the bottle with the lid but not too strong. Shake the bottle and place it on the ground in a state of standing. See what will happen?!


Science-Project-ideas-for-Kids


Not to long you can see that the cap of the Redoxon bottle violently ejected into space, the way it thrown away similar with the movement of a rocket that being launched. Why does this happen?  


The mystery behind this is due to chemical reactions between liquid vinegar with baking soda produces carbon dioxide gas. These gases are gradually becoming more and push cap ejected into space. Other substances resulting from the chemical reaction is the formation of salt crystals. So that was mentioned earlier that the beginning of the experiment is better done in the field. The first reason is so that the cap can slide freely without being obstructed ceiling. The second reason is that the salt produced is not polluting the room and make a mess.


You will see that the kids will enjoy this science project. After the experiment done, you can explain the science reason behind what happened. The kids will be very keen to listen to your explanation because they have witnessed the awesomeness of the result of a chemical reaction. Try to compare with if you directly explain to them that if vinegar (acetic acid) was mixed with baking soda it will form carbon dioxide and salt. They are guaranteed not to be too listening to your explanation. And five minutes later they had forgotten. 


So if you are a teacher or instructor who teaches the kids, be a intelligent teacher or instructor in the process of knowledge material delivery. More multiply involve children in terms of motor. Because learning from direct experience is the best teacher.  Guaranteed even in next several years the kids memories on the material that you teach will remain strong and that memories can be recalled at any time.


 Thus presumably one science project ideas for kids that can we explain. From these examples we can see that we can get science from materials that are added to foods that are all around us. Hopefully useful in increasing your reference in making kids science project.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ;

Scientific Methods Experiments Related on Scientific Work Skills

Scientific Methods Experiments | Experiments can not be separated from the scientific method, in scientific work, a problem solved by a series of sequential activities. Each step is done diligently, carefully, thoroughly, disciplined resilient, honest, open and inquisitive. In other words scientific methods experiments needs to develop a scientific attitude. Scientific work that is based on scientific attitude will produce a scientific truth. The result may be facts, concepts, principles, procedures, theory, and law.


Therefore in scientific methods experiments you have to learn the skills of scientific work. These skills include the process skills and using instrument skills. Processes skills include proficiency in each phase or step scientific work, for example observation skill, process the data, interpret the data and conduct experiments. Skilfully using tools such can use a voltmeter, dilute the solution, using a microscope and make preparations properly

Scientific Methods Experiments


1.    Observation

A basic skill you must have is the ability of observation. Observations can be done by utilizing all the tools senses, i.e. taste, hear, see, feel and smell. However, the human senses tools have limitations, so the observations often aided by tools such as rulers, scales, microscopes, thermometers, voltmeters, pH meter and so on.


2.    Data processing

Data obtained from observations should be communicated to others. Data in numeric form if presented directly tend to be less attractive and difficult to interpret. Therefore, the data can be presented in various forms including the form of pictures, charts, diagrams, tables, and graphs.


In addition to be clever in presenting the data, you also need to practice classifying data. For example the qualitative data form of the characteristics of the creatures examined the similarities and differences, then classified. Examples of corn and soybean crops can be classified as a group because they both produce flowers. But if the basis of grouping is the number of seed pieces, then corn and soybeans were separated in different groups because corn is a monocot, while soybeans are divots. So the basis of the grouping is the similarities and differences in characteristics.


3.    Interpret data


Scientific work is always related to the interpretation of the observed data. Interpret means connecting facts with the data obtained. For example, when you find a fish whose body slick with scaly and slimy, you found the slippery body was necessary so that the fish can move easily in water. This opinion is an interpretation of the fact that the fish body is slick with scaly and slimy.


4.    Doing experiment

Experiments conducted to answer a variety of questions or problems scientifically. The order of the steps in the scientific methods experiments should not be inverted, but doing it step by step. Before conducting research experiments you should make a plan called the proposal. This proposal contained the reason of why the experiment must be held, the purpose, benefits, tools and materials, how to research and research schedule. The experimental results are already contained conclusions were then compiled into a research report. Prepare a research report with good so that others can understand it. Remember that you have done scientific steps in answer a problem so that the results are obtained scientific knowledge.

This is a bit of an explanation of the scientific methods experiments that can we describe. Hopefully this explanation can add insight for you and beneficial both now and in the future.
