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.

Why are umbrellas mostly black in color?
It's just because black colour has an advanced ability to absorb heat radiations much better and faster than any other colour. Then you might ask why does then we use it at sunshine to prevent body from heat. No surprise to your question it's because at the same time black is able to liberate back the absorbed heat at a faster rate. If you doubts this then you doubt about one more thing that why does most of the umbrellas are made silverish inside it. The answer to this is that black expells heat in all directions so in order to prevent heat entering inside the umbrella it is painted silverish inside as silver acts as a mirror, so it just reflects the heat back out to the umbrella. So we finds much cool inside with a silver coated umbrella than a black one.
What is a hypothesis that has been tested over and over again?
A scientific theory is a hypothesis that has been repeatedly tested and still seems to be valid. These theories are tested by using the scientific method.
What are the steps to Scientific Inquiry?
Scientific Inquiry is the ongoing process of discovery in Science. There are 8 steps to Scientific Inquiry.
- Observations - An observation is the process of using one or more of your sences to gather information. There are 2 types of observations. Qualitative observations and quantitative observations. A qualitative obervation is an observation that deals with characteristics that cannot be expressed in numbers. A quantitative is an observation that deals with a number, size, or amount and have a unit.
- Investigative Question (Scientific Question) - Pose a question for your observation.
- Hypothesis - a hypothesis is a possible explanation for a set of observations or answer to a scientific question that is testable. A hypothesis must be testable. This means scientists must be able to carry out investigations and gather evidence that will either support or disapprove a hypothesis.
- Organize experiment - create your experiment to test your hypothesis. Identify the Manipulated, Responding, and Controlled variables. Also make sure you have atleast 1 Operational Definition.
- Test your experiment - test your experiment to see if your hypothesis is true.
- Collect Data - Now you see what happens. Make a table or graph to record the data collected. Analyze the data after they have been collected.
- Conclusion - Consider if there are enough data to support or dis approve the hypothesis. It is also a summary of what you have learned from the experiment.
- Communicate - Share your ideas and experimental findings wiht others through writing or speaking.
What is hypothesis of difference?
The alternativehypothesis (Ha or H1) describes the population parameters that the sample data represent, if the predicted relationship exists. It is always the hypothesis of difference. That is as opposed to the null hypothesis (H0) that describes the population parameters that the sample data represent if the predicted relationship does not exist. See Basic Statistics of the Behavioral Sciences by Heiman.

Investigation
What are the problems can be solved in scientific method?
you can solve many things by doing the scientific method all you have to do is take your time it helps many people
Gathering of data and information to test the hypothesis?
The gathering of scientific information is called research.
Whose work is the link between a scientific discovery and the way science is used in the world?
engineer
Is it possible for all data collection to be made using the same method?
For one particular study, yes. But it is not possible for all data collection across the whole world for all purposes.
What was wrong with Hannah greener?
Let No Patient be Harmed by AnesthesiaBy J.S. Gravenstein, M.D.
On October 16, 1846, Dr. Morton, a dentist, gave the first public and successful anesthetic. He used diethyl ether. The operation took place in the Massachusetts General Hospital. In a matter of months, the idea of rendering patients unresponsive through the use of inhaled drugs had spread to Europe and beyond.
On January 18, 1848, Hannah Greener required the removal of a toenail, a simple operation probably performed in the "office" of the surgeon. Hannah was a 15-year-old English girl. We do not know what her surgeon told her about the hazards of anesthesia. Maybe he said nothing about anesthetic mortality because there were no statistics he might have quoted. Had he said that she had a 99% chance of surviving the anesthetic, she might have considered anesthesia extraordinarily safe. She would have had a vivid image of the excruciating pain she would have experienced during an operation without anesthesia. Alas, she was unlucky. She inhaled chloroform from a cloth. In 1/2 minute her arm became rigid. The operation started. She gave a kick and sputtered at the mouth. Breathing continued for another 1/2 minute. Two minutes from the commencement of the operation she was quite dead (Snow, J: Edinburgh Medical Journal 1849,72; 75-87). The physician administering the anesthetic had no monitors other than perhaps a finger on the pulse and whatever information he could gather by inspection of the patient. He also had little knowledge about the pharmacology of the anesthetic nor of effective methods and drugs employed for resuscitation. He had no access to experts who might have stepped in to help before it was too late.
What are the steps in scientific methods in solving scientific problems?
there are seven steps in scientific methods to solve the problem
1.Systamatic observation
2.Controlled experment
3.Qualitative reasoning
4.Quantitative reasining
5.Mathamatical modeling
6.Predection
7.Verification
How do you turn a regular fence into an electric fence?
The fence must be made of a conducting material, such as steel.
The fence must be isolated from the ground, using insulators. It must not touch the ground or the posts suspending it, except through insulators made of non-conducting material, such as pottery, glass or plastic.
A high voltage, low current, generator can then be connected to it. One pole into the ground, using a metal rod pushed into the ground, and the other onto the fence.
Most generators are driven by a battery, through an oscillator and then a transformer, which increases the voltage.
It is better to use a generator properly manufactured, for the purpose of providing a small shock, without risk of death or fire.
How would you separate a mixture of salt gravel and power?
Salt is soluble in water; gravel is separated by filtering the solution or by decantation.
Power is not a material.
Is the scientific method important to solve problems?
It can be. The scientific method is just another way to write huge numbers or really small numbers. It's much easier than writing out a number like this: 938,343,343,656,543,444,777,325,234,644,675,343.
Answer 2:The scientific method is making observations which lead you to make predictions. You then perform experiments to test those predictions and draw a conclusion. It is very important to humanity since it is the best method to explore our world and logically evaluate our surroundings.
The answer above is NOT the scientific method, it is scientific notation.
How does damage to the ozone affect your life?
Damage to the ozone layer can lead to increased levels of ultraviolet (UV) radiation reaching Earth's surface, which can have negative effects on human health such as skin cancer, cataracts, and weakened immune systems. It can also harm ecosystems, affecting the health of plants and animals.
Which is smaller proton neutron or electron?
The Electron is by far the smallest of the three. Protons are the same size and mass of the Neutron, and they are more than 1,800 times the mass of the electron.
If you don't understand that, here's some form of a table of the masses of the 3 particles:
- Electron: 1/1800 Neutron = 1/1800 Proton
- Neutron: 1800 Electrons = 1 Proton
- Proton: 1800 Electrons = 1 Neutron
the scientific method is called a deductive approach

What is a possible answer to a scientific problem called?
A(n) Hypothesis is a possible answer to a scientific problem.
What are foliated metamorphic rocks?
Foliated rocks have layers in them. We often refer to the layers as Banding.
Why gather data during an experiment?
Gathering data is essential to any experiment. The data helps you comes up with results from your experiment so you can analyze them later for future studies. Without them, there would have been no point doing the experiment to begin with.
