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.

How long does it take for an ice cube to melt at 78 degrees?
it depends upon the amount and the shape of the ice.
Step by step of how to do a science project?
1. Introduction = what is the project main idea or what is it a bout .
2. Hypothesis = a opinion or a believe
3. Materials = things that you use to make a project
4. Procedure -= the steps
5. Data collection = to collect in formation
6. Data analyze = collect the data and what did you get form all the data
7. Conclusion = the summarize
8. Questions
What characteristics must a hypothesis have to be useful in science?
capable of being proven false.
testable
Why do some solids sink and some solids float?
Anything heavier than water sinks; anything lighter than water floats.
Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks.
If the object weighs less than the weight of water that it displaces, then it floats.
What is the zooflagellate method of movement?
Flagellates have flagella, which are tails, that help them move. A flagellum is a bundled microtubule tail that propels them through liquid.
Why are the M and C terminals of a watt meter short circuited?
In a watt-meter there are four terminals:
M,L which are the current coils and
C,V which are called as pressure coils . .
To measure the current the measuring instrument should be placed in series with the load but in case of voltage, the instrument should be connected in parallel to the load . .
therefore M from the current coil and C from the pressure coil are can be short-circuited to measure the power of the given circuit.

Explain the difference between a hypothesis and a theory?
A very complicated question but to pare it down:
An hypothesis is a preliminary answer to a scientific question but is one which needs testing.
A theory is an hypothesis that has withstood numerous tests and has not failed.
Perfume is made up of alcohol, water and perfume oil (fragrance). Alcohol acts as a base that mixes the oil, and also acts as a volatile ingredient to help the perfume molecules evaporate and spread in the air. Perfume fragrances are particularly detectable by the human scent receptors, even in very minute concentrations.
The term bioethical describes questions about what people should do with knowledge in biology that cannot be answered using the scientific method. The scientific method is a method of procedure that consists of observation, measurement, and experiment.
Absolutely, the scientific method is the very backbone of experimenting and only through experimenting can scientists make discoveries. The scientific method is necessary to ensure validity, and reliability, without it we can't trust the results to be accurate or reliable.
What are the four problemsolving steps in the correct order?
1-Understand the problem
2-Gather your resources.
3-Come to an answer.
4-Check your answer and present the solution.

When you add so much solute that no more dissolves what do you have?
A saturated solution is made when you have added so much solute that no more dissolves. The amount of solute needed to make a saturated solution will change with the temperature of the solution.
Can sound travel through oxygen?
Yes, sound can travel through oxygen. Sound waves are able to travel through any medium that has molecules, including gases like oxygen. However, sound travels faster through solids and liquids compared to gases.
" Biotic" Means Living, Therefore, The Question(?) Is Asking :
- Insects
- Herbivores
- Humans That Visit
You Welcome :)
How did the scientific method change the way scientists approached problems?
Unlike most earlier approaches, it did not rely on authorities like Aristolte or Ptolemy or even the Bible. It depended instead upon observation and experimentation.

this supercontinent is called PANGEA. it is the greek word for "all lands".
A pholem is a tube that is made from living cells. Their function is to transport the glucose that is produced by photosysnthesis in the leaves to where it is needed. Pholem cells along with xylem cells produce vascular bundles.
What is the effect of temperature on rates of reactions?
Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.
What factors affect the speed of a computer?
Many things determine a computer's speed. Just about everything inside of your computer (hardware & software) can make a difference. The first and probably most common measurement of speed is the clock-speed of your main CPU. This is measured in Megahertz or Mhz. Quite simply the more the better, and 1000s of Megahertz are measure in Gigahertz or GHz. So 2000 Mhz = 2GHz. Another new development in computer technology has also allowed for multiple cores in a single CPU. This can allow multiple independent processing cores to exist on a single board. With this technology your CPU can processes simultaneous tasks without over-taxing a single CPU. Many other things must be taken into consideration as well though, how much RAM your computer has, how fast your hard drive spins, the size of your hard-drive's main platter, what operating system you have, how many other devices are connected to the computer, how much software you have loaded on to it, etc. The list can literally include everything inside of a computer. A better way to examine the question would be to figure out what task you want to speed up. This could include how fast your computer turns on, how fast it can process multi-media types of data (audio/video), or server level computing for applications, services, and user management. Different hardware and software components affect speed in different ways and sometimes optimizing a computer to perform one specific task can yield better performance results.
