Scientific Method

A hypothesis, or group of hypotheses, that is accepted as consistently valid is a theory. Either a hypothesis or a theory can be ultimately disproven. One definition of a theory is an accepted hypothesis.

No

The results of studying the hypothesis are not repeatable and are open to judgement. The hypothesis cannot be tested by controlled experiments.

Discard or change the hypothesis.

To find out if your experiment went as you as you predicted.

Because it's not scientific, its actually an very old legal principle.

It helps break down big numbers like this

Example:

3,000,000,000,000 equals 3 times 10 to the 12 power because there is 12 0s

a hypothesis is an educated guess of an observation about the world

Sure. But the magnifying glass can't squeeze any more heat out of your light source
than what the source has without the magnifying glass.

The only thing the magnifying glass does is take all of the light ... and maybe heat ? ...
that hits the magnifying glass and focus it down to a very small area. It has no more
heat or light to work with than what enters the glass.

The most efficient way to heat water with a light bulb is to shine the bulb straight up
and hang the pot over it.

A observation is statements that are determined by using your 5 sences

Copepods are a subclass of crustaceans called Copepoda in the class Maxillopoda. There are several orders, each with several genera, each with several species. Just to provide one example out of many species, there is a freshwater copepod found only in the US called Aglaodiaptomus kingsburyae. See http://www.answers.com/topic/copepoda-2?cat=technology

Science is useful everywhere. Having good knowledege is very importanat as it can benefit you when you need it. Like for example, you are lost in the forest and need food, shelter and water. You will know if you learned that if you are lost in the forest at dusk, the sun would be at the west. If your home is east you can go the opposite way. If you are lost at night , you can follow the north star. You might also need knowledge on poisonous fungi and plants and be alert of edible and inedible stuff.

Evidence.

trial-and-error

A parameter is an attribute that refers to the entire population. (For example, the mean price of all motor vehicles in a city). A sample is collected from this population of all motor vehicles in that city to compute a statistic (here, the statistic is the average price of the vehicles in the sample) which is representative of the true price.

Einsten was a theorist, not an experimentalist. He developed theories to explain other people's data, which doesn't really fit in with the formal scientific method taught in schools.

The common salt present in permanent hard water is calcium sulfate (CaSO4) and magnesium sulfate (MgSO4). These salts contribute to the hardness of water by forming insoluble precipitates with soap, leading to the formation of soap scum.

Yes, the scientific method can be used to test supernatural phenomena. So far studies conducted in a scientific manner suggest that supernatural occurrences do not exist.

... Sigh. America. How ashamed i am of thee sometimes...

First of all, there are no two people who are exactly alike in looks. Its physically impossible, even for identical twins, to not have an outstanding feature from the other (One Twin may be taller, or more commonly, have freckles or moles in different places than their sibling)

Second of all, If you really think physical appearance determines intrests/activities/taste, then you are shallow. Each human being is unique in that you have a soul, whether you believe in a greater power or not (Personally, i am an athiest) you have a soul, and the decisions, the intrests, the realtionships and connections that you have shape your soul into a unique body. The Idea of Perfectly (Mentally) Identical Twins is... Orwellian. No two people on this earth are the same, whether it be by looks, intrests, taste, or any other human attribute. Its the beauty of life, that each being is in and of itself a beautiful, completly unique person.

Now, please Go to your local Library and read a book, preferably not one involving large text and pictures -_-

Coughx

it help alot otherwise the world would finish till now from disease of malaria

yes because you need to always remember the 7 rules of safety in case of a emergency

The scientific method is a way explore questions, it is not a way to 'fix' anything.
