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 are the different logical steps in the scientific method?

The steps in the scientific method are:

1.Identification of problem

2.Formulation of hypothesis

4.Experimentation

4.Observation

5.Interpretation of data

6.Conclusion

Define scientific method and its parts?

The scientific method is defined as:

1. Problem solving: Step-by-step approach consisting of

(1) identifying and defining a problem,

(2) accumulating relevant data,

(3) formulating a tentative hypothesis,

(4) conducting experiments to test the hypothesis,

(5) interpreting the results objectively, and

(6) repeating the steps until an acceptable solution is found.

2. Sciences: Rigorous, systematic approach, designed to eliminate bias and other subjective influences in the search, identification, and measurement or validation of facts and cause-effect relationships, and from which scientific laws may be deduced.

Example of observation and inference?

for observation it is the temperature today is 4 degrees Fahrenheit

or inference it is in two weeks, there will be snow on the ground

Explain GET and POST method briefly?

When a client sends a request to the server, the clients can also additional information with the URL to describe what exactly is required as output from the server by using the GET method. The additional sequence of characters that are appended to URL is called a query string. However, the length of the query string is limited to 240 characters. Moreover, the query string is visible on the browser and can therefore be a security risk.to overcome these disadvantages, the POST method can be used. The POST method sends the data as packets through a separate socket connection. The complete transaction is invisible because to the client. The disadvantageof POST method is that it is slower compared to the GET method because data is sent to the server asseparate packets

The loci method is a memory technique that involves?

associating objects or ideas with physical locations.

What is the method of the trireme?

The trireme was a Greek ship that used 3 vertical rows of rowers to attain naval speeds unheard of in that day- 8-9 mph. A percussion instrument and training would keep the rowers in time- something vital for the amount of oars in a tight space. The trireme would not be rowed by soldiers, but by trained rowers. Even with this extra weight, the boat would still out-perform any other boat out there.

Methods used in addressing a collective good problem?

Collective good problem is the problem of "how to provide something that benefits all members regardless of what each member contributes to it". The three principles used to solve collective goods problem are Dominance, reciprocity, and Identity.(By Alpha Otieno)

How do you do a science fair project on ghost?

It would be difficult, if not impossible since we don't know for sure if there are ghosts. That said, here are some things to try:

1. Find a house or location alleged to be haunted. As a matter of etiquette, you should avoid studying politically sensitive areas, and you should have permission from the owners and any survivors if a tragedy is connected. If you cannot find a place alleged to be haunted, you could try places like cemeteries.

2. You should use various types of cameras, including traditional film cameras, digital camcorders, infrared cameras, etc. This would help rule out human intervention and explainable means, and would help clarify things if some cameras capture things and others don't. If you see "poltergeist" activity, make sure you film it if it is safely possible (eg., a chair comes hurling at you out of nowhere).

3. You should use cassette recorders at the location. Those claiming to be "ghost hunters" prefer traditional tape recorders using virgin cassettes.

4. If human intervention is suspected in a "haunted" location, you could install things such as trip wires rigged to alarms, photocell detectors, etc.

5. It would be good to have others with you when investigating. They should have their own equipment and take notes. That way, if you see something that is unusual, others might be able to corroborate.

6. Keep all your documents, recordings, and notes.

7. Optionally, if you are religious or spiritual, you could pray for protection while investigating. Chances are, you won't find anything or run into trouble, but if it is real, then you want to cover all your bases.

Is stating the problem the first step in the scientific process?

Yes, in the Scientific Method, the problem / question / observation is the subject of the investigation. Once the question exists, a hypothesis / conjecture can be made, which can be proven or disproven through experimentation.

What In the scientific method?

The Scientific method involves several sequential steps which allow a standard way of getting to te answer of a question. These, with a simple example, are:

  1. Identify a problem that you wish to investigate as clearly as you can: You want to make sure your car is safe to drive
  2. Based on your impressions identify what you think the answer might be (theory): You think your tire pressure is too low.
  3. Determine what the outcome might be if you are right in this thinking: If you measure the pressure with a gauge it will be less than 28 psig
  4. Do experiments or collect data to see if they confirm the expected results: The gauge says the pressure is 14 psig
  5. Compare your results (real) to the predicted outcome: It is too low!
  6. Make changes or modify your theory (start over again at step 2): Put some air into the tire with a pump
  7. When your expected results and observed results are the same then your theory is probably correct (or almost so): After several cycles of check and pump the pressure is 28.1 psig, that is fine!

At this point most scientists let their results be known for other scientists to check out and attempt to duplicate the findings, This is called peer review.: You ask a friend to check the reading with his tire guage
