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.

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
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.
True or false the scientific method is one step scientists use to solve scientific problems?
Yes, that is a good way to put it.
How do you make a school building using thermocol sheet?
build thermocol charminar build thermocol charminar
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.
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.

Are the enzymes used up by the reaction?
an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation energy required, it does not in itself change during the reaction.
***Note:: Enzymes cease to function when they denature. This usually occurs by pH level changes, or increased temperatures. This occurs because it causes the bond of the molecule to break and essentially changes the shape of the enzyme. Because an enzyme is a lock and key model, when the shape changes it becomes useless

How do you separate sand salt and grit from rock salt?
Rock salt is mined as a solid in salt mines. it does not need to be separated.
Which person is collecting data through the participant observation method?
A. Hassam watches people as they interact.
Why does an objects gets attracted towards moon when it leaves the earth's gravitational field?
The moon orbits Earth because it is held there by Earth's gravity. The moon is going fast enough that it won't hit Earth, but at the same time is being pulled back in at the same rate it flies away. The same is true for why Earth itself doesn't fly into the sun.
the sun is MUCH MUCH MUCH further away than the earth is, so it is attracted to earth because the difference in size and gravity favour the earth. If it was to be attracted to the sun, the sun would need to be bigger or closer (both of which it is doing at aconstant rate, but very gradually over a long perios of time)
How does heat transfer by radiation conduction and convection?
a thermos limits heat transfer through the walls of the thermos. that lets the fluid inside the thermos keeps its temperature nearly constant for a long period of time (whether the temperature is hot or cold).
Maxwell's inductance capacitance bridge?
The Maxwell Bridge is known as an AC bridge. This bridge is used to find the self inductance and the whole amount of a circuit.
What if hypothesis is not supporter by the data has been collected and analyzed?
When a hypothesis is not supported by data, two possibilities exist. The hypothesis can either be rejected and a new one is formulated, or more data is required to retest the hypothesis.
A1 Because water is a solvent, and as long as the material, in this case salt, has less density than the liquid itself, it should sink. But, other solutes like sugar, are denser and water, and will simply sink.
A2 Strictly, there are many many salts, and common table salt, NaCl is the one we meet most commonly. This dissolves readily in water as you remark.
Copper Sulphate 'bluestone' is another salt. Some salts are essentially insoluble, such as many of the Mercury salts - especially the Mercurous ones.
What happens to metal are heated and cooled?
It depends on the metal but often it will change phase and crystal form and have different properties. As an example steel when molten is in what is called the austenitic phase. This is a face Centered Cubic crystal structure. When quickly quenched it becomes martensitic which is brittle and Body Centered Tetragonal. Cooling down slowly will produce a pearlite structure.
If a liquid metal is poured into a mold it will take the shape of that mold and when cooled will keep the shape of that very mold. It will also contract/shrink.
