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.

How do scientist collect data?

Scientific investigation is based on observations. Observations refer to any information we collect about the

physical universe using our senses (sight, sound, smell, taste, and touch.) The factors or conditions being

observed are called random variables (or experimental variables) because our observations of them can vary

from one trial to the next. A random variable can be either discrete or continuous

Is it possible to conduct a scientific experiment without the control variable?

you can conduct the experiment but it will not prove anything because you will not have anything to compare it to. For example, if you soak a potato in salt water and it grows in size, how would you know if it was the water or the salt that made it grow? You would have to soak a potato in plain water and one in salt water to see what happens.

What is the definition of scientific question?

The definition of a scientific question is a question that can be answered using experimentation and factual reasoning. Some examples are:

  • What is the universe made of?
  • How did life on earth begin?
  • What is consciousness?
  • What is at the bottom of the ocean?

What are the points to note in using the Bunsen burner?

- Never leave the gas on when the flame is out

- never put anything you don't intend to heat

- ensure the tube is arranged properly as if it is turning here and there, the gas might just be stucked somewhere and there will not be any fire burning

- never touch the collar(the neck) as it is very hot and when it strikes back at the gas

hole, off the gas immediately.

What is the weight of 1 cubic meter of stone?

It depends on the specific weight of the special sort of stones. 1 cubic meter of water weighs 1 tonne.

What does indirect observation mean?

The members of a population may be small or hard to find. Indirect observation is when it would be easier to observe what the animals left behind, like a nest or tracks, rather than the organism themselves. Ex: If there are 120 nests in an area, you can find the number of swallows by multiplying 120 by , or 480 swallows.

Can you give examples of 'inferences'?

== == Inference is when u, what the heck, i don't know.

What is an example of an observation?

lets say thare is a black, blue ,red, and brown cat that is big and has small feet. the details are the observation

the details are black, blue, red, brown, big, small feet.

you observed how they look.

What is experimental bias?

Experimenter Bias, also known as Experimenter Expectancy, is made up of all the things an experimenter might unwittingly do to influence the results of an experiment to resemble his hypothesis. You could consider this a self-fulfilling prophecy to some extent.

What is observation method?

something that is observed and can generally not be measured.

What is the method used to solve a resultant vector?

If you mean "What method is used to make a resultant vector into its components?" then the answer is called "resolution" and you can google it for details. If you mean "What method is used to detirmine a resultant vector?" well that one doesn't have a name as far as I know. Basically, you set up a visual representation of the forces and use trigonometry to find the length and direction of the resultant. Now, to find the resultant, you would draw a diagonal line. You can then make a triangle where one side has a length of 6 and the other 8. Because these two sides are at a 90 degree angle, you can use the pythagorean therum (a^2 + b^2 = c^2) to find the diagonal line which is the resultant vector. Hope this helps :) -Angelic Endeavor Minor Edit By Me: I had trouble formatting the pictures, I hope it works this time. Edit 2 By Me: I can't get the visual aid to work so you'll have to use your imagination, sorry. :(

What are scientific attitudes?


First off, the question should be "What ARE scientific attitudes?"

A scientific attitude starts with the goal of objectivity, personal detachment, reliance on measured evidence, following some sort of coherent process, recording and documenting observations and results, references to previously published literature and the work of others, and publishing conclusions for "peer review" by other scientists with qualifications in the specific area of inquiry. Science is the constant acceptance of being incorrect or seeing things in probability of being accurate and letting the figures and processes used speak for themselves as evidence of accuracy. No reliable scientist would say that something is a fact or proven (that is for math people) but would speak in terms of probability and what the observations and measured data indicate or suggest.

What is a parts of experiment?

parts of an experiment
  • Hypothesis {[A statement that can be tested}]
  • Prediction or Inference {[Prediction based on observations}]
  • Independent Variable {[The variable that is changed}]
  • Dependent Variable {[Factor that is being measured}]
  • Conclusion {[The result of the experiment}]

Hope this helps you :) ;)

Why is it important that you test only one factor at a time when you perform an experiment?

This is one of the basic principles of the scientific method. Let's say you do an experiment and you change two things at once. How do you which thing you changed affected the result of the experiment? By keeping everything exactly the same as before and changing one thing at a time, you know that any change in the result of the experiment was due to the change in that one thing.

Let me use an example. Let's say you are measuring how fast you can drink water (don't ask me why you would do that experiment!). So you could vary a few different things to test... like change the water temperature from hot to cold, change the shape of the container you are drinking from, or maybe even how thirsty you are! But if you want to know the affect of the temperature of the water (can you drink a cold glass of water as fast as a room-temperature glass or a glass of hot water?), you don't want to change from a cup to a squeeze-style bottle at the same time. If changed both things at once, you wouldn't know whether you could drink it fast because of the temperature or because of the container, right? But if you compare different temperatures water, all from the same container, you know that whichever you can drink faster was because of its temperature!

Has anyone encountered feeding problems with the model 60 when using subsonic ammo?

Not much info in the question, but try this. IF the Model 60 is a .22 long rifle, and a semi-auto, you very well might run into failures to feed or eject of you use sub-sonic, or standard velocity, ammunition. Most semi-autos are set up to work with the high velocity, or supersonic, .22 ammunition. Standard velocity ammo is often manufactured as high quality target rounds. The reason for this is that, since the bullet does not exceed the speed of sound, it won't make a sonic boom..or crack, in this case. The theory is that breaking the sound barrier makes a .22 bullet a little less accurate. For small game hunting and most other uses, the high velocity round is plenty accurate, and tends to put small game down a lot more reliably and humanely, especially if hollow point bullets are used. Since the subsonic rounds are a little slower because they're a little less powerful, they may not alway generate enough pressure to activate a common blowback action semi-auto rifle. If you try high velocity ammo and it works fine, you have the answer to your question.

*** Good info there, also try this: Clean your feed ramp. Subsonic ammunition is usually very soft, and can foul the entire action. Ammunition such as Aguila and others that offer very low velocity subsonics don't provide enough force to properly cycle the action. If you're getting a lot of cases that 'stovepipe' where the spent case is not fully ejected from the action, you're probably using a subsonic that's too slow. Try Remington or CCI subsonics. They both function nicely in all my .22 semiautos, including my venerable old Mod 60. ______________________________ I'll also add that in .22lr bulk packs, avoid Remington Golden like the Swine Flu. They are inconsistant at best...maddening with squibs & short-powder on a regular basis. Sub-sonics tend to be spotty in performance with semi-auto's that use standard blowback actions.

What is meant by scientific management approach?

The scientific management approach, developed by Frederick Winslow Taylor in the early 20th century, emphasizes optimizing work processes to improve efficiency and productivity. It involves systematically studying tasks to identify the best methods and practices, standardizing work procedures, and using metrics to measure performance. This approach advocates for the division of labor and specialized training, aiming to maximize output while minimizing costs. Overall, it seeks to apply scientific principles to management to enhance organizational effectiveness.

Identify and select the correct order of steps in scientific inquiry?

5 and 7 Step Methods

The 5 Step Method:

  1. define the problem
  2. create a prediction that provides explanation
  3. create a scientific procedure to test the ideas
  4. observation of results in the procedure
  5. form a conclusion based on all of the other steps.

The 7 Step Mehod:

  1. Ask and define the question.
  2. Gather information and resources through observation.
  3. Form a hypothesis.
  4. Perform one or more experiments and collect and sort data.
  5. Analyze the data.
  6. Interpret the data and make conclusions that point to a hypothesis.
  7. Formulate a "final" or "finished" hypothesis.

With the investigation concluded, the published results will be verified by other investigators, and the "tested" knowledge integrated into a larger whole of scientific information.

More Information:

It is important to note that there is no one single scientific method. Every experiment is different and may or may not follow the exact steps; science is less structured than most realize. However, there are key elements of the experimental process that we can identify.

In experiments (and in everyday life), scientists (and non-scientists) use hypothetico-deductive reasoning, or "If...then logic" to identify and test problems and solutions.

The start of every experiment does not start with "asking a question." It actually starts just before that. If you think about it, you cannot ask a question without identifying a problem that you observe. You do not ask "how does an owl hunt at night?" without first observing that an owl successfully captures mice as a food source at night. So this is where we start -- observation.

Now we go to our question. You have just observed a natural phenomenon, and now comes the time to question why this is.

As is our nature, we set out to answer this question. But first we need a tentative solution to our problem/question in order to test this theory. This is called a hypothesis; an educated guess. It is important that this hypothesis be able to test in an experiment. In other words, your hypothesis cannot be "because ghosts are playing tricks", because this is untestable and outside the realm of science.

So we have our tentative answer to our problem/question, and now we need to test this hypothesis. But usually we don't rush head-on into a task without knowing what our result should be. Therefore, we make a prediction, which will explain our results.

We have our hypothesis that we're going to test, and we have our predicted result should the hypothesis be true. Finally, we get to test and perform the experiment.

If this test supports the hypothesis, then additional predictions may be made and another test is performed. If the test does not support the hypothesis, then revision of the hypothesis is needed and a retest is performed.

Application of hypothetico-deductive reasoningObservation: My flashlight doesn't work

Question: What's wrong with my flashlight?

Hypothesis: The flashlight's batteries are dead.

Prediction: If this hypothesis is correct

Experiment: and I replace the batteries with new ones,

Predicted Result: then the flashlight should work.

Step 2. Hypothesis

Step 3. Method/Experiment

What scientific attitudes did francis crick possessed?

Francis Crick was an English scientist who won the Nobel Prize for medicine. He had the attitude that conventional science did not have all the answers, and he believed in investigating all possibilities in the areas in which he worked. This led him to be one of the people who discovered DNA in the 1950s.

How scientific attitude can be developed?

In general terms, a "scientific attitude" consists of a disciplined commitment to careful observation and experimentation as the surest means of obtaining new knowledge or refining already-established knowledge of empirical phenomena. It may be developed through formal educational programs or through conscious choice on the part of an individual who engages in self-guided study and practice of a scientific nature.

What are the activities involved in scientific method?

Multiple activities are involved in executing the scientific method. These include the formation of a hypothesis/thesis, research, reading, experimental testing, modeling, citation of sources and peer review.
