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.

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.

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

What is part of an experiment that is not being tested an is used for comparision?

This probably refers to the 'control'. In a very simple experiment you may add food colouring to a solution to see what colour it sent the solution. You would also have a second sample of the solution which you would not add food colouring to. This would be your control and would serve the purpose of making sure that the solution wouldn't have changed colour by itself anyway. It would also be there for comparison, so that you could compare the colours to see just how much the colour had changed.

How does the steepness of a ramp affect how fast an object moves?

The steepness of the ramp affects the direction of the normal force of the object on a ramp (which is always perpendicular to the ramp). The net gravitational force is always straight down.

Using the angle of inclination of the ramp with Trigonometry, you can find the vector forces of gravity perpendicular and parallel to the normal force which makes up the net gravitational force. The parallel portion is in the same direction of the ball rolling down the ramp. This will give you your force of acceleration, which you can use in basic equations to find the velocity of the object.

The steeper the ramp, the faster the object rolls down. A ramp of 0 degrees would result in a ball just sitting on the ramp as normal force and gravitational forces cancel each other. A ramp of 90 degrees would be like a cliff and this would produce the fastest velocity since the ball is moving in the same direction as the force of gravity in free fall. A ramp with an angle between these means that part of the gravitational force is being offset by the normal force.

How are repetition and replication alike and different?

replication- the action of copying or reproducing something.

repetition-the action of repeating something that has already been said or written.

They are basically the same,but they have a few differences. Replication is like cloning something. Repetition is just repeating something. Repetition is just repeating something. Like with chromosomes, when they reproduce they replicate themselves. If there is a repetition in the gene there is an error. Hopefully you are catching my drift. They are very similar in the fact that with both you are doing something one or more times exactly the same. Hope I helped. :)

Which recovery method usually involves an evasion effort an is dependent on the ips condition?

An unassisted recovery method usually involves an evasion effort and is dependent on the IP's condition.

Can you calculate your average speed while walking at different speeds?

For the speed of a single pedestrian, measure the time it takes him/her to walk a set distance (for example 10 meters) and divide the distance by the time. For the average speed of a pedestrian find a large number of people and measure the speed of each person and find the average by summing all the speeds and dividing by the number of people who took the test.

Is a theory or a hypothesis?

Evolution is an observed and observable fact. The theory of evolution by natural selection explains many things about evolution. The theory generates testable hypothesis, as any good theory does. Remember, theory is the highest concept in science.

What are the main steps of the scientific method in order?

1. Observing

2.Hypothesizing and Predicting.

3. Experimenting.

4.Organizing and Analyzing Data.

5. Drawing conclusions.

6. Repeating Experiments.

Which is an example of a method that may be used to gather data?

Cookies are the most common legally used information gathering techology.

Key loggers are used to gather your information as well, but they're usually included in malware and viruses, not usually used legally.

What is the difference between scientific method to non scientific method?

The Difference between the two is that firstly, the scientific method relies purely on data gathered for inferences about a question while other methods (philosophical for example) rely on conjectures or ideas put forth without measurable observation. secondly the a conclusion drawn with the scientific method will have either support or criticism from peers, who through their own data or observations will prove to strengthen the conclusion. the experiment and results of the scientific method also comprises it's own data which supports itself while a philosophical method does not have evidence outside of the idea holder's thoughts.

How do scientist use scientific method?

Scientists use the scientific method when there's a problem that can't be solved. Because it is a logical, orderly way to solve a problem or answer a question.The scientists follow the steps of scientific method. 1.Observation 2.Gather info about the problem 3.Formulate a hypothesis 4.Experiment 5.Record data based on the experiment 6.Formulate conclusions 7.Report research methods
