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.

Wegener hypothesized that, on earth, there was only one continent called Pangea, but it split into the continents we have now.
Improved Another Answer:
Wegener's hypothesis was that long 225 million years ago, there was a supercontinent called Pangaea (All the continents were all together).
Wegener saw that South America and Africa looked like they could fit together like puzzle pieces. He then found that there were fossils of animals in a warm climate and it was also in a very cold climate. He thought, "How could that be? The animal couldn't have lived in two different kinds of climates and how could it have swam across the sea?!"
What are two chemical properties of iron?
Physical Properties of Iron
1. Boils at 2750°C
2. Iron's density is 7.874g/cc
3. It is silver- white when pure
4. Its atomic mass is 55.847
5. It reflect 65% of the light that hits it
Chemical Properties of Iron
1. Oxidizes in damp air
2. It dissolves quickly in dilute acids
4. It corrodes fast in high temperatures
5.When iron is exposed to air it reacts with oxygen
to form hydrated ferric oxide on its surface (rust).
What are the steps of a scientfic method?
Ask a Question
Do Background Research
Construct a Hypothesis
Test Your Hypothesis by Doing an Experiment
Analyze Your Data and Draw a Conclusion

How has the nature of science and the scientific method changed over time?
I dunno. It has developed a lot due to experiments.
P.S I think that's right!! lol
:-D
Hope I helped!!!!
What is the metric root for length?
I'm am not sure if you mean the measurements but if yes the answer is simple. Volume is measured in the same units as length except after the measurement you add a little 3. eg. 35cm3 (a small 3 on the top on the side i put the three on!) The reason the three is there is because in volume there are three dimensions, thus the term 3D.
Here is the system I follow by:
10mm3=1cm3(or 1cc-cubic centimeter)
100cm3=1m3
1000m3=1km3
I hope I have helped.
P.S: I am a person in my 6th year of school and my name is Ray-Jean and again, I hope I helped!
Why was wegener's hypothesis not widely accepted at the time it was prospered?
Wegener was ignored for so long because no scientists believed him about his theory of continental drift. No scientists believed him because he couldn't explain how the continents had moved until the time of Harry Hess or J. Tuzo Wilson.
Your guess to what you think what will happen. The above answer is for a "HYPOTHESIS", however the true question here is an anatomy question of "What is the Hypophesis?". To begin "hypophesis" is actually spelled "hypophysis". The hypophysis is AKA the pituitary gland. Some people also mistakingly use the word hypophysis to describe premature portions of bone in relation to the "physis" (aka:growth plate), inwhich there is no such thing in relation to the bones.
What does initial observation mean?
For example, a guy notices that his shower is covered in a strange green slime. His friend tells him that coconut juice will get rid of it. he decides to check this out by spraying half of the shower with coconut juice and other half with water after 3 days no change on either sides of the shower.
The initial observation in that story would be that "the shower is covered in a strange green slime."
What does analysis mean in scientific method?
it mean when u are doing your project your supposes to observe what u are doing and write it down
Is the first step of a scientific experiment the hypothesis or problem?
Scientific Method
1.Problem
2.Research
3.Hypothesis
4.Expeirment
5.Analyze
6.Conclusion
So problem comes before hypothesis
What are the six steps in the USAF lockout and tagout program?
1. Notify - Notify the machinery and equipment owner/operator of the upcoming work to be performed. If there is a question about who the affected workers are, the authorized worker shall notify the machinery and equipment owner/operator. In all other cases, the authorized worker must notify affected employees.
2. Shut Down - If the machine or equipment is operating, shut it down by the normal stopping/sequential procedure (depress stop button, open toggle switch, etc.).
3. Isolate / Relieve Energy Sources - Operate the switch, valve, or other energy isolating devices so the equipment is isolated from its energy sources. Dissipate or restrain stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) by methods such as repositioning, blocking, bleeding down, etc.
4. Lockout - Lockout or tagout the energy isolating devices with assigned individual locks or tags (methods selected; i.e., locks, tags, additional safety measures, etc.).
5. Verify - After ensuring that no personnel are exposed, and as a check on having disconnected the energy sources, operate the push button or other normal operating controls to make certain the equipment will not operate (types of equipment checked to ensure disconnection). CAUTION: Return operating controls to "off" or "neutral" position after the test.
6. Perform - The equipment is now locked out or tagged out and service work can be performed.
How matter and scientific method help in human?
It helps you by helping you to conduct the experiment appropriately.
Why must a scientific begin by making observations?
Generally, one makes a casual observation - apples fall from a tree - and from this one generates an hypothesis - a casual explanation for the observation.
With the hypothesis in mind, an experiment is designed to test or prove/disprove the hypothesis.
With a sufficient number of experiments under your belt, you may now form a theory, which is a much firmer type of being. It may be capable of more general application.
When a gas is being formed what is the observation that can lead to a conclusion?
air bubbles,colour change,go look on bitesize
Is it true or false that a scientific experiment can be conducted only in a laboratory?
No. Experiments can be done anywhere. Laboratories are indeed handy as they have equipments and surroundings needed for most of the experiments, but you cannot limit experiments to the labs.
A:The answer to this actually depends on how you define the word laboratory.
If by a laboratory, you mean 'a special room set aside to conduct scientific experiments' then the answer is no. Experiments can be conducted in the field (in other words, outside the lab or even outdoors) in what is known as field research.
However, if you define a laboratory as 'a place in which experiments are conducted' (as in, "The whole world is my laboratory") then the answer is yes. By this definition, wherever you happen to be conducting your experiment - the classroom, the beach, the International Space Station, or even inside your own head - would be considered your lab space.
The way you've phrased the question, however, makes me believe that you intended the word laboratory to have the first definition, i.e. a lab room. By that definition, the answer you're looking for is false, for the reasons outlined above.
What characteristics must a hypothesis have to be considered scientific?
To make your hypothesis considered scientific it must have testable and measurable results.
Example: If you do an experiment and the results are testable and measurable another person would be able to do the exact same project and come out with the same results.
A. True
What question about the world around you could be answered using the scientific method?
Those based on observation, measurement, and reason.
What is this called when scientists do their test more than once?
Scientists do their test more than once, or get their colleagues and peers to do the same experiment in order to verify the results of their experiment.
This is called reproducing an experiment and its results.
What method do you use to separate iron filings from sawdust?
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.
A researcher finds that her data does not support her hypothesis what conclusion can she reach?
end the experiment and throw away the datarepeat the experiment until the hypothesis is supportedchange the hypothesisargue that the results were
