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.

When is the hypothesis formed in scientific method?
A hypothesis is formed after observations are made and a question is formed.
Scientific Method:
1. Make an observation.
2. Ask a question.
3. Make a hypothesis.
4. Conduct an experiment.
5. Draw conclusions.
6. Share your results.
7. Do other experiments done by others agree?
8. Yes or no?
9. if no, do again.

What is the decolorizing agent in the acid fast stain?
The decolorizing agent in the acid fast stain is acid alcohol. The decolorizing agent in the gram stain is ethanol.
Place the four steps to the elimination method in the proper order?
Find the variable with equal or opposite coefficients.If equal, subtract the equations. If opposite, add the equations.Solve the resulting one-variable equation.Substitute the known value into the other equation and solve for the remaining variable.
Why scientific methods cannot be used to answer ethical questions?
The scientific method is problem solving procedures. Ethics is moral beliefs that is good and bad some people believe in different things and cannot be proven because other science explanations actually have no evidence to prove it.
Try to come up with a different hypothesis that seems to be supported by the data.
These should be as similar as possible to the real thing?
Copy, clone, duplicate, facsimile, counterfeit, twin, etc etc
What are the 3 postulates of science?
1. Every phenomenon has a cause.
2. Every cause can be known and understood.
3. All causes and phenomena act the same always and everywhere.
Why is it important for experiments to be written in scientific method?
All experiments are based on hypothesis that has to be tested for truth. All scientific experiments therefore follow a logical methodology to arrive at a conclusion that must have a universal result that becomes universal accepted truth in Scientific experiments. It is necessary to follow the universal methodology by collection of the data for analysis to determine the elements or functional relationship in the experimental process. It is similar to any mathematical function that proceeds from one step to the next with the application of a universal formula that is written when solved.
Common mineral that breaks along smooth flat surface?
cleavage, if a natural property of the mineral (e.g. mica); or a fault, such as in a gemstone.
Why are controls important when testing a hypothesis?
By having a control (which is subjected to the same conditions as the test subject[s] except for the condition or substance you are testing) you can eliminate other influences, by comparing the control to your test. In testing medication, for example, this is VERY important - if only to account for the PLACEBO EFFECT that occurs.
By having a variable, you can compare the results of a series of applications of the specific condition or substance you are testing, which should show at what level(s) the experiment works and possibly what side effects occur.
More Information:
The variable provides the data that are to be interpreted and compared.
The control provides a reference, or standard, for comparison. Without this reference, no valid comparison is possible so, the data is moot, and the hypothesis can't be tested.
When does a chemical reaction take place?
A chemical reaction occurs when the conditions for a chemical reaction exist.
Which is a really lame answer, so let's play with it. You want to make some water and carbon dioxide. You have some hexane, which is C6H14. If you set the hexane on fire, it will react with the oxygen in the air to produce carbon dioxide and water.
What is the melting point for nonmetals?
The melting points for non-metals range from the lowest for all elements to the highest. The melting point for Helium is effectively 0 K (-273.15 deg C) whereas that for Carbon is 3823 K (3550 deg C).
Why might a scientist need to repeat the scientific method?
An experiment should be repeated for two reasons. The first is that you want to be sure that your results stay the same. If they are different the second time then it shows that the result are not constant, and therefore cannot be used to prove a point. The second is that other should be able to repeat it to make sure that your did not make up your results.
What is Bonding by electron transfer?
Valence electrons are the parts of the atoms involved It is the electron.
As electrons are fermions (1/2 integer spin) they obey the Pauli exclusion principle so that no two electrons can occupy the same energy level. This gives rise to the electrons of different atoms unable to be in the same energy level and this is where the bond comes from. If they could occupy the same energy levels like bosons (eg the photon in laser light) then there would be know chemistry.
How are inferences drawn from observations?
Generally, inference means an educational guess or a judgement. Observations are the cause of any major or minor change.
This might not help much but that's all I know.
What are the key component of the observation step of inquiry?
The five key steps in the inquiry process are:1. Ask a geographic question
2. Acquire geographic data
3. Explore geographic data
4. Analyze geographic information
5. Act on geographic knowledge
What does trend mean when referring to science projects?
A pattern of evolution in which direction of change is persistent over an appreciable span of time.
Which step of the scientific method should be done throughout an experiment?
The scientific method that should be done throughout an experiment is to state the problem.
Which is not a key assumption to the Scientific Method?
Empiricality
The assumption that I am still alive is not critical to scientific notation.
List ways that hypothesis can be supported?
Pictures,explantions,or demonstrate. . i hope you like my swords too.:D

What is true for those assigned to a control group?
Those in a control group would not know they are in the control group, and they would not receive whatever manipulation that is being tested. If it is a drug being tested, those in the control group would receive a placebo (typically sugar pills or saline injections). If it is a behavior being tested such as exercise, the control group would either do a behavior like reading that has nothing to do with the experiment, or they would just mentally visualize that they are doing what is being tested (such as pretending to exercise). Now, if visualizing is the experiment, then maybe there should be two control groups, one that actually does what is being visualized, and one that does a more sedentary activity that has nothing to do with the experiment.
