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 the variable that a scientist observes to change while conducting an experiment?
Depends on the experimnet, if you testing a reaction of metals with carbonates for example the variables might be; the size of the metal/carbonate, the amount of metal/carbonate, the from of metal e.g. solid or liquid
Scientists encourage other scientists to review and repeat their experiments so that their hypotheses may become Scientists encourage other scientists to review and repeat their experiments so that their hypotheses may become
When does the scientific community accept the results of a scientific experiment?
after it has been tested against a control group with stats
What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
What should you do for your science fair project if you are in the seventh grade?
As a 7th grader, also looking for a science fair project, I bet you are wanting to do something fun, simple, and that has a good chance of becoming award winning...
Right???
Well if so, here's my ideas:
1)NOT A VOLCANO...everybody does that in like the 2nd grade. It's so gay.
2)Somehting you like or are interested in like a sport or some kind of food, ETC.
3)If you can't think of anything either you are retarded or you just simpley not trying hard enough....
Sorry if I didn't help you but one more tip:BE SERIOUS ABOUT YOUR PROJECT BUT ALSO HAVE FUN!!! Just remember that it's better than writig notes for the houur of Science class...lol
here are some websites for some ideas

The scientific method emphasizes which method of attaining knowledge?
= Scientific and unscientific method of acquiring knowledge? =
How did the scientific method threaten the Catholic Church?
The scientific method is based off observation, experimentation, and learning things through your 5 senses.
The Catholic Church stressed faith and belief in what they told others. Sometimes, what you believe, cannot be determined as truthful through observation, experimentation, or your five senses.
Historically speaking, science quickly began to dispel a lot of the Church's traditional beliefs (i.e. the earth the is the center of the universe) and this upset the Catholic powers.
What are the five major steps of the scientific method of solving problems?
The five(5) steps to the Scientific Method:-
*Problem:Stated as a question/
*Hypotesis:- a scientific or educational guess.
*Materials:- list all the materials that are used in the experiment.
*Procedures:- list step by step directions needed to be followed for this experiment.
*Results/Conclusion:-re- state your problem/question. Answer your hypothesis(was it correct or not.)Gather together all your information.
What are some advantages and disadvantages of aluminum?
well they are used for your mom when i did her and then you came in and i said what the hell get out of here werid o and take that aluminum can with you that's my hor and your pratice toy get it out of here
Which is the correct order for the following steps of the scientific method?
Observation, hypothesis, experiment
What is the melting point of polypropylene?
The softening temperature of polypropylene is 150 degrees Celsius. Its melting point is between 160 and 170 degrees Celsius.
Where was the scientific method created?
Yes, it has a scientific method.Actually, there are 5 steps of scientific method. First, Identify the problem. Second, Gathering Information and Data. Third Formulate Hypothesis. Fourth, Experimentation. and Fifth, Conclusion. Scientific method is a logical way solving problem scientifically. I hope this will help. :)

Does scientific method ensure objectivity in research?
Scientific method does ensure objectivity in research. It also ensures that personal bias and emotional involvement do not factor into the results of the research.
reactant substances usually come from groups 1 and 7 on the periodic table as it is easy to gain or lose 1 electron
What is the Function of the Measuring Cylinder?
A measuring cylinder also called graduated cylinder is laboratory glassware used to measure the volume of liquids. Some of its functions are the following: it is used at home when there is a need to measure volume of liquid ingredients required for a recipe and itÕs also used to accurately measure liquids used in chemistry or biology laboratories.
What is the difference of relative density versus density?
Now, let's say you have some other substance that also occupies one cubic meter but weighs 2000 kilograms. It has a density of 2000 kg/m3. In other words, relative to water, the substance is twice as dense as water. Now you have an idea of what relative density is.
If we use water as a reference, we can compare other substances' densities to the density of water. Simply divide the substance's absolute density by the absolute density of water to get the relative density of the substance (relative to water). Relative density is a unit-less quantity; it is just a number. If a substance is denser than water, its relative density will be greater than one. If it's less dense than water, it will have a relative density less than one.
Relative density is also known as Specific Gravity.
In what ways does koch's procedure demonstrate the use of scientific methods?
Koch's Postulates (Procedures):
Step 1. ASSOCIATION: The suspected pathogen must be consistently associated with the diseased plant (or animal).
Step 2. ISOLATION: The pathogen must be isolated and grown in pure culture and its characteristics described.
Step 3. INOCULATION: The pathogen from pure culture is inoculated into a healthy plant of the same species or variety and it must produce the same symptoms and signs.
Step 4. RE-ISOLATION: The pathogen is re-isolated from the inoculated plant and its characteristics must be the same as the organism initially isolated in step 2.
Ask a question- Is this a pathogen
Do Research- find the suspected pathogen and isolate it and grow a pure culture
Construct a Hypothesis-
Test- Inject suspected pathogen into healthy organisms
Analyze and Conclude- If suspected pathogen has produced same signs and symptoms in multiple tests on same organisms then it is indeed a pathogen

Does salt effect the freezing process of water?
Salt molecules bond with water molecules, making it more difficult forr icce to form. The results is a lower freezing temperture. For example, a 10% salt solution freezes at 20'F (-6'C) , while a 20% salt solution freezes at 2'F (- 16'C).
What is the method of solving scientific problems based mostly on observations?
im not exactly sure what it is but i think it might be a 11 letter word second letter is e
Why are glass tubings rotated while being heated?
Since glass is a poor conductor of heat, it may crack on uneven heating. Therefore, in order to heat it evenly, you have to rotate the glass tubing.
What bias is in an scientific experiment?
If for example, some of the measuring equipment were incorrectly calibrated. For example a cloth measuring tape will over time, stretch, and thus underestimate the true length. If a beam balance were not correctly leveled, then the balance point would be wrongly shown, and the weighings would be in error. These errors would be bias. In addition, there are some operator errors. A well known one is for a particular operator, when estimating the fine graduations of a scale, to have a bias towards even numbers.
