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 scientific attitude and The Scientific Method?
Scientists must have a skeptical attitude.
As well, all Experiments are conducted by The Scientific Method.
What are the seasons in the southern hemisphere?
They are "opposite" of the northern hemisphere. When it is summer in the north, it is winter in the southern hemisphere. Therefore fall in the northern would be spring in the southern, winter in the N would be summer in the S, spring in the N would be fall in the south.
Seasons in the Southern Hemisphere:
- Summer: December - March (northern winter)
- Fall: March - June (northern spring)
- Winter: June - September (northern summer)
- Spring: September - December (northern fall)
A structured procedure for collecting information to test a hypothesis is?
It is called an experiment.
expiriment
Acceleration can be defined as the rate at wich velocity?
Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating.
This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.
I don't know if this is true, but my old science teacher at high school told us all that 'a piece of the sun the size of your fingernail, a mile away from you, would still be able to kill you with the heat it gives off".
Where does water enter a starfish?
Water enters the starfish through the madreporite or the tube feet, but mainly the madreporite.
What relationships among heat movement and density in mantle rock?
As mantle rock is subjected to heat, it becomes less dense and can undergo convection, where hotter, less dense material rises and cooler, denser material sinks. This movement of mantle rock due to differences in density plays a key role in driving plate tectonics and volcanic activity on Earth's surface. Heat helps drive these density-driven movements by changing the physical properties of mantle rock.
Who is Dr Fred Whipple and explain his hypothesis?
Whipple came up with the "dirty snowball" concept of comets; that the head of the comet is primarily ice and frozen gasses bound together by dust, gravel and rocks. This explains the nature of the "tail" of the comet; as the frozen gasses sublimate away (change from solid to gas, without an intervening liquid state) the gas is carried away by the solar wind and by pressure of the sunlight itself.

How are the knockout mice useful in determining the function of genes?
Knock out mice are produced by impairing or deleting a particular gene expression. Thus the gene function (which was deleted) can be tracked by studying this knock out and the control mice. Lets say a gene is suspected to trigger immune response against a pathogen, one can study this by infecting the wild type(normal) and knock out(specific gene deleted) mice and study the role of the gene.
What is the difference between experiment and hypothesis?
An experiment is the thing that you perform, and a hypothesis is the guess you make at the start (before the experiment) to determin what's going to happen.
What is a variable that does not change in an experiment?
The variable that stays the same throughout the entire experiment is called the control.
Who is father of silver revolution?
Dr. Verghese Kurien is known as the "father of the white revolution" in India, which transformed the country from being a milk-deficient nation to the world's largest milk producer. However, there is no specific individual known as the father of the silver revolution.
How do you do the stepping method from kenichi?
It's a little hard to explain without showing you, but here goes:
First, point your toes together with your heels about a foot apart. Next, move your left foot backward so that it is perpendicular (makes a right angle) with your right foot.
When you're using this technique, make sure that when your toes are together, you put each foot around one of you opponents feet.
Define operational definition as distinct from lexical definition?
Operational can be defined as the process of operationalization that is used to define a variable or an object in terms of a process that is needed to determine its quantity, duration, and existence. An operational definition can, when operationalized to a greater degree, besides the procedure needed to bring something into existence.
