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.

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.
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

What are the set of steps scientists use to answer a question or solve a problem?
The scientific method is the process used by scientists to answer questions. The steps of the scientific method are:
- Ask a Question
- Do Background Research
- Construct a Hypothesis
- Test Your Hypothesis by Doing an Experiment
- Analyze Your Data and Draw a Conclusion
- Communicate Your Results
However, when a hypothesis comes out to be false in the "Analyze your data and draw a conclusion" step, you rethink the problem, with the new information gained by doing the experiment, and start back on the "Construct a Hypothesis" step and continue though.
The experiment must also be repeatable to truly count as scientific.
When water changes from a liquid state to a solid state we say it as?
gas -> liquid = condensation
liquid -> solid = solidification (freezing)
solid -> gas = sublimation
gas -> solid = deposition
solid -> liquid = melting
liquid -> solid = vaporization
What makes a good scientific conclusion?
To write a good science lab conclusion you should use the RERUN procedure. The RERUN procedure means:
Recall what you did during this lab.
Explain why you did this lab and what you were trying to find out.
Reflect on the lab's meaning and did it match your hypothesis or was your hypothesis wrong? and why?
Uncertainty (errors that were in the lab that you could not control [aka: weather problems, measurement mistakes] or just any errors that you came across during running this lab that you could fix for the next time you perform the lab).
New questions or new discoveries (normally you put in at least three).
Make sure you do not put in 1st or 2nd person in this lab (ex: me, you, I, we) because it will be too formal and the lab isn't supposed to be about you it is supposed to be about the experiment you performed.
Make sure you CHECK FOR ERRORS! Use spell check and get your peers to review it for you.
Otherwise, just follow what your teacher said to do and try to follow RERUN as it will be very useful to you and it will help make writing your conclusion easier.
What is observable in salt in water?
An observable properties of salt and water as they combine in a mixture is that salt will dissolve in the water. You can see that this combination of the solute salt with water a solvent produces a homogeneous mixture.
Is lysosomes a prokaryotic or eukaryote cell?
It is neither a prokaryotic or eukaryotic cell because it is not a cell. It is an organelle. They are found in animal cells and are vesicle like, they contain digestive enzymes which are used to break down "old" organelles.
How did the scientific method change the way scientists worked beginning in the 16th century?
… They experimented more.
How is hypothesis and scientific method are related?
Hypothesis is just a temporary solution to your problem and an educated guess and should be supported by facts while the Conclusion is the part summarizes your findings and provides the answer to your research problem.

How did Sir Isaac Newton help with the scientific method?
Newton could be called the father of Mathematical Physics. Newton's helped explain the underlying "laws" that produced the observations of Kepler and predicted the return of Haley's Comet.
Newton introduced used the of idea of a cause and effect to explain the work of other scientists. Many people saw the apple fall but Newton asked How and Why it did not fall up?
