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 set of steps scientists use to answer a question or solve a problem?

The scientific method is the process used by scientists to answer questions. The steps of the scientific method are:

  • Ask a Question
  • Do Background Research
  • Construct a Hypothesis
  • Test Your Hypothesis by Doing an Experiment
  • Analyze Your Data and Draw a Conclusion
  • Communicate Your Results

However, when a hypothesis comes out to be false in the "Analyze your data and draw a conclusion" step, you rethink the problem, with the new information gained by doing the experiment, and start back on the "Construct a Hypothesis" step and continue though.

The experiment must also be repeatable to truly count as scientific.

When water changes from a liquid state to a solid state we say it as?

gas -> liquid = condensation

liquid -> solid = solidification (freezing)

solid -> gas = sublimation

gas -> solid = deposition

solid -> liquid = melting

liquid -> solid = vaporization

What makes a good scientific conclusion?

To write a good science lab conclusion you should use the RERUN procedure. The RERUN procedure means:

Recall what you did during this lab.

Explain why you did this lab and what you were trying to find out.

Reflect on the lab's meaning and did it match your hypothesis or was your hypothesis wrong? and why?

Uncertainty (errors that were in the lab that you could not control [aka: weather problems, measurement mistakes] or just any errors that you came across during running this lab that you could fix for the next time you perform the lab).

New questions or new discoveries (normally you put in at least three).

Make sure you do not put in 1st or 2nd person in this lab (ex: me, you, I, we) because it will be too formal and the lab isn't supposed to be about you it is supposed to be about the experiment you performed.

Make sure you CHECK FOR ERRORS! Use spell check and get your peers to review it for you.

Otherwise, just follow what your teacher said to do and try to follow RERUN as it will be very useful to you and it will help make writing your conclusion easier.

What is observable in salt in water?

An observable properties of salt and water as they combine in a mixture is that salt will dissolve in the water. You can see that this combination of the solute salt with water a solvent produces a homogeneous mixture.

Is lysosomes a prokaryotic or eukaryote cell?

It is neither a prokaryotic or eukaryotic cell because it is not a cell. It is an organelle. They are found in animal cells and are vesicle like, they contain digestive enzymes which are used to break down "old" organelles.

How is hypothesis and scientific method are related?

Hypothesis is just a temporary solution to your problem and an educated guess and should be supported by facts while the Conclusion is the part summarizes your findings and provides the answer to your research problem.

How did Sir Isaac Newton help with the scientific method?

Newton could be called the father of Mathematical Physics. Newton's helped explain the underlying "laws" that produced the observations of Kepler and predicted the return of Haley's Comet.

Newton introduced used the of idea of a cause and effect to explain the work of other scientists. Many people saw the apple fall but Newton asked How and Why it did not fall up?

How can a hypothesis be proven correct?

A hypothesis is a prediction of what data should come out. If the data fits it, or is acceptably close, then you can use it as proof; if it is outside an acceptable error or is not conclusive, then you can then alter your hypothesis or discard it completely and try another.

What are the 7 parts of the scientific method in order?

problem,observation,inference,hypothesis,experiment,conclusion,result

Why is acid alcohol rather than ethyl alcohol used as a decolorizing agent in the acid fast staining experiment?

Alcohol is a term used for any O-H group that is attached to a carbon.

Perhapes the alcohol is found in a Safranin stain. I hope I have this right but if alcohol was used as the decolorizing agent, it may wash out too much stain to get a good view in an oil emersion microscope.

Part of earth's interior that flows like plastic?

Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.

Has scientific knowledge changed over time?

New experiments are performed or old experiments are repeated and confirmed or contridicted. From this expanded pool of experimental data, new or refined theories can be made, which then provide hypothesis for new experiments that will either confirm the new/refined theory or support the original theory. The process is then repeated and science marches onwards.

Is melting cheese a reversible change?

no, you cannot get cheese back to cheese when melted

What method should be adopted to solve a complex problem?

Break it down into a sequence of simpler problems, each of which may be broken down further until the problems are simple enough to be easily resolved. Each simple solution should be implemented as a simple function with just one or two very simple statements. Breaking problems down in this way makes code easier to read, especially when each function's name closely reflects the purpose of the function (rendering code self-documenting). Once you have a working solution, you may find some of the simple functions can also be used to solve other complex problems, thus reducing the need to write duplicate code.

What is the purpose of conducting a scientific experiment?

The purpose of a Science laboratory is to carry out small experiments ( trials) and see whether an experiment is successful.If this expt is successful in the Lab then one can use this expt on a bulk scale for any purposes like manufacturing of a product, or research a product or carry out practically anything or replicate the lab Process.

Is this statement an observation or an inference the cat must be ill?

It's an inference because your drawing a conclusion (that the cat must be ill)so it is inferrence

How would you repair an electric fan using scientific method?

.,.,.the SCIENTIFIC METHOD usually begins in OBSERVATION w/c leads the formulation by HYPOTHESIS that can be tested by EXPERIMENTATION, and then you may now list/analyze the DATA after that the last is to GENERALIZATION.,.,

How do you know if a hypothesis is testable?

To be truly testable, a hypothesis should be falsifiable, with counter-testing and proof of the null hypothesis possible.

First you have to find a problem then find a question or what you are going to test. An example would be paper towels, such as how much weight they can hold. A hypothesis would be, "Bounty will hold over two hundred pennies. A hypothesis is an educated guess.
