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
From the Miriam Webster online dictionary empirical means: 1 : originating in or based on observation or experience 2 : relying on experience or observation alone often without due regard for system and theory 3 : capable of being verified or disproved by observation or experiment AND - From a Psychology dictionary : Derived from naturalistic observation of from experimental procedures. Empirical evidence is evidence from observations. From my understanding it can be through naturalistic observation (the in depth observation of a phenomenon in its natural setting) or Experimental (maniplulating an independent variable to observe its effects on a dependant variable). Experimental evidence is much more reliable as naturalistic observations are vulnerable to researcher bias. Empirical evidence is a fancy way of describing facts that can be experienced and tested only through the senses. I suppose you can only compare that to mathematical or logical facts, which depend on reasoning alone (as in the solution of a quadratic equation, for example). Different types of `truth' are discussed by philosophers such as Aristotle, Kant, and Descartes, and the theory of knowledge is sometimes described as `Epistemology.' It's one of the most contentious areas of philosophy, particularly with reference to science and social sciences. epw (B.A. in Philosophy) Scientific evidence is considered empirical when it can be observed by many people and all will agree as to what they observed. An example would be reading a thermometer. No matter who observes the thermometer, it still displays the same temperature. The counterexample to this is physically sensing warmth or coolness. Observer A might sense that a room is warm, while observer B senses that the same room is cool. These observations differ depending on the observer, and are therefore considered subjective. Evidence that is not dependent on the observer (i.e., is objective), that appears the same no matter who observes the evidence, is considered to be empirical evidence. dcs (PhD in Nutrition, research neuroscientist) Empirical evidence is evidence acquired by observation.
What are the scientific methods?
The scientific method involves coming up with a hypothesis. It also involves conducting research and deducing inferences from the findings.
Enumerate the four different scientific methods?
know the problem, gather facts and datas, make experiments and observation, hypothesis and conclusion
What was the goal of the scientific method developed by Bacon and Descartes?
The goal of the scientific method developed by Bacon and Descartes was to establish a systematic approach to acquiring knowledge through observation, experimentation, and logical reasoning. They emphasized the importance of empirical evidence and rational thinking in understanding the natural world. Their methods laid the foundation for modern scientific inquiry.
What was the Philadelphia Experiment and what were its results?
The Philadelphia Experiment is a myth. It never happened. Supposedly it was an attempt to turn warships invisible which resulted in severe disruptions of the space-time continuum with people disappearing and reappearing at different places and times or being physically merged with parts of the ship. I want to emphasize again though that none of this ever happened. Michael Montagne
What are the three glands that help to complete the digestions?
