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 correct order for the first three steps of the scientific method?
The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.
What physical and chemical properties are used to separate metals from their ores?
Some impurities ,or unwanted substances ,are less dense than water ,so they float in water and can be washed away.Others ,like sulfur ,can be burned away.
Explain how refractive index of liquid is determined by using Newtons ring experiment?
After experimental arrangement, the glass plate is inclined at an angle 45° to the horizontal. One or two drops og the given liquid is placed between the glass plate and lens. This glass plate reflects light from the source vertically downloads and falls normally on the convex lens. Newton's rings are seen using a long focus microscope, focussed on the air fil. The cross-wire of the microscope is made tangential to the 20thring on the left side of the centre. The readings of the main scale and vernier scale of the microscope are noted. The cross wire is adjusted to be tangential to the 18th, 16th, 14th, etc on the left and 2nd, 4th, 6th, etc on the right and readings are taken each time. From this the diameter of the ring is found out which is the difference between the readings on the left and right sides. The square of the diameter and hence Dn2 and D2n+m are found out.
What simple machine can increase force?
A lever can increase force by allowing the user to apply a smaller force over a longer distance to produce a larger force over a shorter distance. This mechanical advantage provided by the lever can make it easier to lift heavy objects or move them over a shorter distance.
How fast does a bean seed grow?
Unless you're trying to grow a real life Giant Beanstalk, you're definitely not going to take that long for a bean plant. Most bean plants only take about two months from planting to produce fully mature beans.
What organic compound within your body does DNA code for?
DNA codes for the amino acids in proteins. The DNA code indicates the sequence of amino acids in a protein. The sequence of amino acids determines the three-dimensional structure of the protein, which determines its function.
What conditions will the magnitude of the displacement be equal to the distance?
Only if your entire walk is in the same straight line. Otherwise, no.
Example:
Start anywhere on the track at the high-school football field, and walk all the way around it.
The distance you walk is 1/4 mile. Your displacement is zero, because you're now standing
exactly where you began.
What is the difference between scientific method and scientific attitude?
Scientific method refers to the particular process of solving problems--based on observation, empiricity and attribute of repetitiveness. Scientific attitute refers to willingness or temperament to follow/adopt this process for solving problems.
How much voltage does it take to power a clock?
My big kitchen clock runs on a single AAA cell. That's 1.5 volts.
My son has a solar-powered watch. The solar cell is a lot less than 1.5 volts.
I used to have a clock in my office that ran on the voltage between two needles stuck into a potato.
I had to get rid of it after a long weekend when the clock was stopped and the office was full of fruit flies.
But the potato was not a tremendous voltage source.
I don't know what's the smallest voltage that a clock has ever run on, but it's obviously a lot less
than one volt.
What type of reasoning was used in the development of evolutionary theory?
A Theory is a hypothesis that has withstood testing, but cannot be proven infallibly true, meaning that the only way to form a theory is through scientific testing. Reasoning is necessary to form a hypothesis, which will be considered a theory once tested and supported by the results. Two types of reasoning are Inductive Reasoning and Deductive Reasoning.
Inductive ReasoningMaking observations and extrapolating to come to a conclusion beyond the scope of current information.i.e.
The grass outside is green
therefore
All grass is green
Deductive ReasoningUsing logic to reach a conclusion, specifically when the conclusion necessarily follows the premise(s).i.e.
This mouse is gray
and
All gray mice are fast
therefore
This mouse is fast
Once you have a hypothesis, it can be tested using the Scientific Method.
Scientific Method- Ask a question
- Do background research
- Construct a hypothesis
- Test your hypothesis using an experiment
- Analyze data and draw a conclusion
- Communicate your results
If the results of the experiment support the hypothesis, then it is considered true. If others are able to duplicate the experiment and achieve the same results, the hypothesis will be considered a theory.
inductive
Is a manipulative variable the same as an independent variable?
Yup, a manipulative variable is the variable a scientist deliberately changes. This is also called an independent variable.
Why do engineers use the scientific method?
The scientific method is beneficial for a variety of reasons. Some of these are:
- The steps are clear, so the experiment can always be repeated
- Experiments are controlled
- Allows the results and work to speak for itself
- Has a clear objective and minimizes bias
In the scientific method how do you test a hypothesis?
1. Ask a question
2. Make a prediction
3. Plan and conduct an experiment
4. Communicate their results
Take this make-believe scenario: I am investigating the properties of water, and I need to know all I can about how water, ice and heat interact. I know that when water gets cold enough, it freezes, and that when ice is exposed to heat, it melts. I might come up with a hypothesis-- a first attempt to understand what is happening with water and ice. I hypothesize: Since water is the liquid state of H2O, and liquids are warmer than their solid forms, water must be warmer than ice. It must be that as soon as water forms from melting ice, it is at least a little warmer than the ice. After all, at zero degrees water becomes ice. At this point, I do not know for sure, but I am speculating (hypothesizing) based on the general information that I have. I wonder how I can test my hypothesis: Let us assume that I can measure the temperature of ice and of water with great accuracy. I should be able to easily make a mixture of ice and water, while measuring the temperature of each independently.
- If my hypothesis is correct, I will find that at one atmosphere of pressure and in a chamber kept at exactly zero degrees Celsius the ice will warm to zero degrees Celsius and it will get no warmer. When it is warmer, it is water and not ice.
- I will also observe that the water will be at least a little above zero degrees Celsius when it first melts away from the ice.
- I apply heat to the ice and some ice melts.
Answer A hypothesis is tested by designing an experiment to prove or disprove it. The new Hadron Collider is trying to prove or disprove several hypotheses. One is that there is a particle called the Higgs boson. So watch out for the results.
Parts of the scinetific method?
Ask a question. Form a hypothesis. Prodedure. Data. Evidence. Conclusion. Reasons for error.
There are many other forms of the scientific method. If this is not useful... One word for ya... GOOGLE!
What is the correct order for performing these activities?
stretch, warm up, exercise, cool down
I Know but in A+ is like that
Warm Up, Stretch, exercise, cool down
What are the three major steps of the scientific method?
Actually, your question is imprecise. there are five: initial observation, hypothesis, experimentation, data, analysis, and conclusion. If you absolutely need to have just three, then hypothesis, experiment, and conclusion is... best. :)
Who introduced the scientific method?
The scientific method was developed over a few centuries, especially in the Renaissance. Galileo had a big part on developing it. Francis Bacon developed the scientific method.
What is the different shape of scientific method?
The scientific method is a scientific method for systematically acquiring new knowledge. The scientific method is typically applied to experiments, involving taking a hypothesis and using it to get applicable results.
