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 one can make a photoelectric cell to illuminate a room?
To make a photoelectric cell to illuminate a room, you would need to use a light sensor (such as a photodiode or phototransistor) that detects ambient light levels and triggers a circuit to turn on artificial light sources like LEDs or bulbs. The sensor would need to be connected to a control circuit (such as a microcontroller) to regulate when the lights turn on or off based on the light levels detected. This setup would allow the photoelectric cell to automatically adjust the lighting in the room based on natural light conditions.
What is the control of a experiment?
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
use the important words from the paragrah and it would make a good conclusion
Who invented 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 are the advantages of using the dollar-value LIFO method?
There is pretty much only 1 advantage of LIFO: tax deferral.
Is time dependent on mass energy and distance?
Time is not dependent upon anything. Time is what it is.
However, the amount of time necessary for something to happen IS dependent upon the amount of energy put into it, the amount of mass it is happening to and the distance across which it is happening.
Who invented the Fahrenheit scale?
Daniel Gabriel Fahrenheit (24 May 1686 - 16 September 1736), a German physicist and engineer.
Although his scale is usually defined by the freezing and boiling points of water, boiling was not one of his reference points, but the normal human body temperature was.
The German instrument maker Gabriel Daniel Fahrenheit (1686-1736) made the first reliable thermometers. The temperature scale he originated is named after him.
Gabriel Daniel Fahrenheit, a German physicist, invented the temperature scale he named after himself.
The Fahrenheit temperature scale was proposed the Dutch-German-Polish physicist Donald Gabriel Fahrenheit in 1724.
The big idea of energy What us the big idea of energy?
Most of what goes on in the universe-fromexploding stars and biological growth to the operation on machines and the motion of people-involve some sort of energy being transformed into another. The concept of energy is relevant to more than one discipline of science.
Why do dark colors attract more light and heat than light colors?
They do not attract light, they absorb it, that is why they are darker. Light colors reflect more light (to your eyes), that is why they are light.
it has to do with the light energy that doesn't stop, lighter colors tend to reflect when there isn't a place for the light to bounce off of it has to stop and the energy remains as heat
because dark traps the light and doesn`t let go
What is the purpose of the scientific method?
The purpose of the scientific method is to remove as much human bias and opinions from science.
What are some good science project ideas?
Maybe:
A Baking soda Rocket
Flower growth project
Purifying water samples
Examining which balloons last longest
or examining which type of battery lasts longest
Also, try doing something that fascinates you. See if you can prove which household cleaner is best, which plant formula is best, which liquid is the most flammable. What ever you like.
In the fields of science a theory is the framework of proven or demonstrative facts. It is never "just a hunch" or hypotheses, which are unproven.
A theory is an explanation. It summarizes a hypothesis based on experiments and tests that have been performed.
Theory" is a Jekyll-and-Hyde term that means different things depending on the context and who is using it. While in everyday speech anything that attempts to provide an explanation for a cause can be dubbed a "theory", a scientific theory has a much more specific meaning.
How do scientists test hypotheses?
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.
What are differences between the light microscope and the electron microscope?
A light microscope uses a light source but a electron microscope has beams of electrons focused by magnetic lenses.
The major difference in practice is resolution: the amount of detail that can be discerned in the image. Under optimal conditions (excellent lenses, oil immersion) the resolution of a light microscope is about 0.2 micrometers (or 0.000,000,2 meters or 2 thousandths of a millimeter). Objects that are closer together cannot be detected as separate. The resolution of an transmission electron microscope is about 0.05 nanometers (or 0.000,000,000,05 meters or half of 1 millionth of a millimeter). This means that the electron microscope has about 10,000 times the resolving power of the light instrument, and can therefore show far greater detail, for example of subcellular structure.
Another difference of importance to biologists is that light microscopes (there are several kinds, such as bright field and phase contrast) enable the viewer to watch living cells. The electron microscope produces an image of the shadows cast by atoms of heavy metals used as stains; the living tissue is destroyed by the intense beam of electrons.
scientific attitude acts like a framework for scientific method. having such attitude help us to do the researches with no preconsumption and so we can see what really exist.
What are three tools used to analyze data?
Thermometer, Spring Scale, and a Balance Scale ;-) Math Homework... Suckie! :P
How do you build a spaceship using the scientific method?
To build a spaceship using the scientific method, you would first research existing knowledge and technologies related to spacecraft design. Next, you would make a hypothesis about the design features needed to achieve space travel, then test and refine these ideas through experiments and simulations. Finally, you would analyze the results and draw conclusions to inform the construction of the spaceship.
What does theory mean in the scientific method?
theories can incorporate facts and laws and tested hypotheses
What are scientific methods used for?
scientific methods are used for identifying the problem, forming and testing a hypothesis, analyzing the test results, and drawing conclusions.
What skills do scientists use?
Skills that a scientist have is observing before they experiment.
Scientists also mix things without exploding their chemicals.
A scientist never quit and try things to learn more about a toping.
They measure things to calculate them.Scientist is a(n):
Open-minded person
Intellectual Honest
Respectful
Creative
Critical Thinker
