Scientific Method
The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What is the first step to a masters in psychology?
You will need a BA (bachelor's degree) in psychology or a related human services major. Once you have obtained your BA, you will most likely need to take the Graduate Record Examination (GRE) and possibly the GRE Psychology subject test, depending on the requirements of the university you wish to attend. Check out the website of the school you're interested in to find out all the requirements for the MA.
What is difference between scientific and unscientific method of research?
scientific is science and unscientific method is not scientific
A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.
What is the role of Tris-HCl in phage preparation by PEG precipitation?
To Prevent Possible protease contamination
Why is the Bunsen Burner named after RW Bunsen if he didn't invent it?
The Bunsen Burner is named after RW Bunsen because he played a key role in popularizing its use in laboratories for heating and sterilization purposes. Although Heinrich Desaga actually invented the burner, Bunsen's improvements and advocacy led to its widespread adoption and recognition in the scientific community.
How do magnets affect crickets?
There have been no scientific studies done specifically on crickets. Though there have been many studies done on other animals.
What can you write when your hypothesis is correct?
You write that the data supported your hypothesis.
What is the Tomatis method used for?
The Tomatis method is used for conditions including dyslexia , attention deficit hyperactivity disorder (ADHD), Down syndrome, chronic fatigue syndrome , autism, depression, and behavioral problems.
What is difference between a hypothesis and a scientific hypothesis?
A scientific hypothesis has to be testable.
How do you make a bow from a fishing rod?
To make a bow from a fishing rod, remove the fishing line and reel from the rod. Curve the fishing rod into a bow shape, making sure it has enough flexibility. You can then attach a string to the ends of the rod to complete your makeshift bow. Remember that a fishing rod may not be as effective as a traditional bow for archery purposes.
What is the discussion in an Experiment?
An Experiment has no use without its documentation. Regarding this: The Lab Book; it contains - Protocol; Equipment; chemicals this and procedures that, compression of the results occurs in the Conclusion, while The Discussion is the Section of the Report that follows the Conclusion.

What is the latest scientific developments?
This could be a tough one, but the BIGGEST recent one would have to be the 'water on the moon' test. NASA crashed a probe (on purpose) to see if there is water on the moon. The data's come back, but we still don't know!
Which dissolves better in water salt or baking soda?
if you add baking soda to warm or cold water it will dissolve better and faster than salt!
Why brown spot is formed while preparing chappati?
it can be due to burning or dehydration, i am not sure
What is gathering information by measuring or counting is called?
Quantification, although the collection process could be called data collection (just a guess :)
Why is probability important to a scientist?
Some but not all scientific models are based on the ability to determine the likelihood that a given experimental outcome has happened by chance alone. If you have an accurate understanding of how the variables in the experiment change when nothing in particular is affecting them, then you have a way to establish some confidence that your outcome is the result of your experimental procedure and not the result of purely random events. The experimental 'lingo' is that the researcher has to determine if the 'Null Hypothesis' can be rejected. The Null Hypothesis is that the experimental outcome is not significantly different from what you would expect if the experiment had no effect at all.
As an example, if the probability in the natural world is that some event will happen by chance only one tenth of one percent of the time, then when I observe that event as my experimental outcome, I can be reasonably sure that my procedure has brought about the event; it is so unlikely that it happened by chance. It is not perfect, but few scientific procedures are. This also highlights the importance of replicating studies or of doing meta-analyses of experimental data gathered in many experiments to further reduce the likelihood that observed outcomes are nothing more than chance events.
Why are umbrellas mostly black in color?
It's just because black colour has an advanced ability to absorb heat radiations much better and faster than any other colour. Then you might ask why does then we use it at sunshine to prevent body from heat. No surprise to your question it's because at the same time black is able to liberate back the absorbed heat at a faster rate. If you doubts this then you doubt about one more thing that why does most of the umbrellas are made silverish inside it. The answer to this is that black expells heat in all directions so in order to prevent heat entering inside the umbrella it is painted silverish inside as silver acts as a mirror, so it just reflects the heat back out to the umbrella. So we finds much cool inside with a silver coated umbrella than a black one.
What is a hypothesis that has been tested over and over again?
A scientific theory is a hypothesis that has been repeatedly tested and still seems to be valid. These theories are tested by using the scientific method.
What are the steps to Scientific Inquiry?
Scientific Inquiry is the ongoing process of discovery in Science. There are 8 steps to Scientific Inquiry.
- Observations - An observation is the process of using one or more of your sences to gather information. There are 2 types of observations. Qualitative observations and quantitative observations. A qualitative obervation is an observation that deals with characteristics that cannot be expressed in numbers. A quantitative is an observation that deals with a number, size, or amount and have a unit.
- Investigative Question (Scientific Question) - Pose a question for your observation.
- Hypothesis - a hypothesis is a possible explanation for a set of observations or answer to a scientific question that is testable. A hypothesis must be testable. This means scientists must be able to carry out investigations and gather evidence that will either support or disapprove a hypothesis.
- Organize experiment - create your experiment to test your hypothesis. Identify the Manipulated, Responding, and Controlled variables. Also make sure you have atleast 1 Operational Definition.
- Test your experiment - test your experiment to see if your hypothesis is true.
- Collect Data - Now you see what happens. Make a table or graph to record the data collected. Analyze the data after they have been collected.
- Conclusion - Consider if there are enough data to support or dis approve the hypothesis. It is also a summary of what you have learned from the experiment.
- Communicate - Share your ideas and experimental findings wiht others through writing or speaking.
What is hypothesis of difference?
The alternativehypothesis (Ha or H1) describes the population parameters that the sample data represent, if the predicted relationship exists. It is always the hypothesis of difference. That is as opposed to the null hypothesis (H0) that describes the population parameters that the sample data represent if the predicted relationship does not exist. See Basic Statistics of the Behavioral Sciences by Heiman.
