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.

Is the cat must be ill an observation or inference?

I think it is a inference because you are observing the cat.

Which statement best describes the method or methods used to gather scientific data?

Experimentation and observation are methods used in gathering scientific data that can then be used to answer questions and solve problems.

If 500 g of KCIO decomposes and produces 303 g of KCI how many grams of O2 are produced?

The balanced reaction from the problem is 2KCIO -> 2KCI + O2 So if 303g of KCI is formed that is approximately 1.702 mol (303 g / MW of KCI (178 g/mol)). For every 2 moles of KCI formed there is 1 mole of O2 formed. Therefore, 0.851 mol of O2 are produced and multiplying by the MW of oxygen (32 g/mol) will yield 27.23 g of oxygen.

What was Dr Kettlewell's hypothesis?

He said that moths with darker color were less likely to be eaten by birds. He said that pollution causing soot on walls of building "selected" for darker colored moths because the birds could not see them as well. So more darker moths produced offspring like themselves. Kettlewell said that differential selection by birds using their eyesight to find prey was sufficient to explain the changes in darker pigment, and that this demonstrated the effectiveness of natural selection as an evolutionary force.

Did Albert Einstein use the scientific method?

Yes. Einstein was certainly a proper scientist. There are many versions of the "Scientific Method". But they have several Greek notions of logic and reasonableness, despite the details. # Observation # Hypothesis # Experimental Data # Analysis # Conclusion # Publish # Retest (frequently done by others) See:http://en.wikipedia.org/wiki/Scientific_method Usuallly the "Scientific Method" addresses a problem that seems to be unanswered or unanswerable by the current orthodoxy, possibly posed by an observation that does not fit the present model. An hypothesis is crafted that explains the observation. The hypothesis is tested and analyzed. Conclusion are drawn consistent with the results of the experiment. The data and experimental details are published so that others may redo the experiment or comment on the test. This technique has variations from one field to another and one situation to another. Some experiments are never re-done, but the experimental data is reanalyzed carefully. Sometimes results are never openly published for security reasons. A good way to see how the Scientific Method works is to imagine leaving out key parts, and then judging whether or not you can depend on the answer....Probably not!

What effect can new observations have on scientific theory?

If new observations are discovered that clash with the previous theory, then the theory will have to be revised.

What are the 5 steps to financial empowerment for females?

The first step to achieving financial empowerment as a female is to find the right financial advisors who can help you plan for your future and ensure that you meet your goals and commitments.

Once you have found a team, the second step is to educate yourself and learn some of the basics (you want to be somewhat financially literate). Understanding interest rates and compound growth can go a long way. Be sure to monitor your credit score since high and bad credit scores can impact your interest rates and affect things like buying a car, home, etc. Next, be sure you are preparing for retirement by making contributions to your 401K and making sure you are putting enough money away for your retirement. Lastly, figure out what you will be able to collect from your Social Security once you retire.

When do the ice turns into water and when do water turns into ice?

The state of the water depends on the temperature of the water and the surroundings. If the water is below freezing point, the water will begin to freeze, and thaw when the temperature rises above the freezing point.

How are observations and hypotheses related?

observations and hypotheses are related let me just say it like this u need one of the other to make the other one with out one there would be the other one
