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.

Where did Gregor Mendel first learn about flowers and fruit trees?

He first learned about them when he was on a journey to Mecca. His best friend and long time girlfriend Phoebe was alaong for the ride, and she had fallen, breaking her face. They tried to figure out whys he had fallen when a leaf monkey came up form behind and started to throw coins at them. This is when the lightbulb was invented.

Name six processes that are often involved in scientific inquiry?

1. Use your experience to help you characterize the problem.

2. Form a conjecture (or hypothesis) that explains the observations and measurements of the subject.

3. Deduce a prediction from that explanation (reasoning including logical deduction[30] from the hypothesis).

4. Test - conduct experiments that test the predictions.

5. Publish and subject the above to the scrutiny of your scientific peers.

A hypothesis can always be proven true?

At a certain point it needs to be testable or it's just wrong

Why metal cups keep hot water hot the longest?

Because metal absorbs and conducts more heat then most other substances so it keeps it hot. Just like when you cook, you use metal pans because they conduct the most heat.

What is a statement that can be tested and that explains what you think will happen in an experiment?

The hypothesis is the cornerstone of science, and hypotheses can be constructed areas, hypotheses may be reached inductively, and a set of competing hypotheses.

What is a question that cannot be answered by the scientific method?

Does God exist? this question is subjective (opinion) and is down to someones individual thoughts

I would agree that science cannot answer this question at this time but that does not mean it is subjective. There are cases in which this is subjective (e.g. when God is defined as an idea as opposed to a non-mental entity) but there are also cases in which this is objective (e.g. when God is defined as Lord Zeus, a celestial entity physically extant and sitting upon the top of Mount Olympus.)

The reason the scientific method cannot answer this question is that in the absence of any conclusive empirical evidence (either via experience or experiment) science cannot say anything conclusive about a topic. Using the scientific method it is usually quite hard to say anything about 'hidden' entities which our senses and tools cannot interact with. The absence of evidence is not evidence of absence.

What step in 6 step scientific method would you list the materials and procedure for the lab?

State a Question

Make a hypothesis

Make Observations

Gather Data

Make a Conclusion

And see uf your hypothsis was right or wrong...

Can a scientific model explain observations?

Scientific models change to reflect ongoing research to explain discrepancies in current theory versus actual experimental results.

No one, with the possible exception of your mother-in-law, knows everything, so we continue trying to explain why the current models work most of the time but not all of the time.

For instance, Isaac Newton developed a few laws of things in motion that worked perfectly and without fail for apples falling on your head, bowling balls and freight trains in motion, but when a few people tried to "smash the atom", that is, to shoot a subatomic particle into the nucleus of an atom, it didn't work. Using Mr. Newton's laws and calculations, they missed every time.

So along came Albert Einstein and mentor max Planck and a few others and, voila! we have a new set of rules, a new model, which works perfectly for little tiny particles...and voila again, we hit the thing dead center.

I doubt that the rules of motion for little particles work for bowling balls, so we still need a tweeked theory that works for both - a new model once again.

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.

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.
