Your assignment is to do the following:
1. Research and determine the difference between Scientific Law and Scientific Theorey.
2. Find a Scientific Law (you can't use the same as anyone else in the class so post yours as soon as you find one!) and post it AND explain what it means.
3. Create your own Scientific Theorey (be creative) and post this as well. You will also need to explain this to your classmates.
4. You will also need to comment on at least one of your classmates Laws or Theories.
Have fun. This is due when you come back to school Wednesday!
Thanks,
Heister

Newtons Law of Motion: First Law-"Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force."
This means that if there is no non-zero net force the object will remain at rest or move at a constant speed.
-Mikayla
First Law of Thermodynamics - "The change in a system's internal energy is equal to the difference between heat added to the system from its surroundings and work done by the system on its surroundings." In other words if you apply heat to a system, either the internal heat will rise, or the system will do work.
Archimedes principle: An object is immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.
This means that when an object floats, the force of the water exerting on it and the force it is exerting on the water is the same.

Scientific theory is an explanation of why and how a specific natural phenomenon occurs. Scientific law is a logical, mathematical statement describing a consistency that applies to all members of a broad class of phenomena when specific conditions are met.
Fourier's Law of Heat Conduction
The Law: Fourier's Law of Heat Conduction deals with the transmission of heat in materials. The law states that the heat flux, Q (the flow of heat per unit area and per unit of time), is proportional to the gradient of the temperature difference.
--this means that fourier believed that heat was brought upon the materials used and transission flow of it.
My scientific theroy- I really had trouble with this one. . :( help..
to mikayla. . very very very true! haha. but seriously I agree because if there isn't force then why would it move. . hmmm
Avogadro's law-two given samples of an ideal gas, at the same temperature, pressure and volume, contain the same number of molecules. Thus, the number of molecules or atoms in a specific volume of gas is independent of their size or the molar mass of the gas.
Lenz's Law:
"An induced current is always in such a direction as to oppose the motion or change causing it"
This means that when you put a magnet(North side first) throught a coil of wire, and an electric current is formed, the induced current in the wire will flow in such a way as to create a north pole to oppose the magnet.
Rue's Theory of Assignment Grades
Late or incomplete work will result in a reduced assignment grade.
Basically, when you don't turn your homework in on time, or just don't do it, you will not get full credit for the assignment.
Boyle's Law-For a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional (while one increases, the other decreases).
-Arturo Antelmo Corrales Garcia
Scientific Theory- Gravitational pull isn't really what keeps planets from crashing into the sun or into each other. My theory is that each needs a certain amount of heat to sustain some sort of balance. Example, Mercury needs X amount of heat to be able to function well, so it moves to where it meets the desired amount of heat. So, if each planet needed more or less heat it would move toward or away from the sun accordingly.
-Arturo Antelmo Corrales Garcia
The law of conservation of energy states that energy in a system does not change over time, and that energy cannot be created nor destroyed.
My theory is that computers and similar information systems will one day be completely integrated into life, giving us computer access everywhere and greatly enhancing the capabilities of what we and other objects can do.
Also, Arturo: So basically your theory is that the planets are somewhat like giant living organisms that need an ideal amount of heat to sustain their ideal "life"?
A scientific law explains what nature does while a scientific thoery explains how nature works. My law is Kepler's Law of Planetary Motion-The orbits of the planets follow around the sun on a desinated line, never breaking this line. My sicentific thoery is that because everything in nature occurs almost always in balance there would need to be a counter part universe that was exactly identical to this one in every single way except for the fact that it's atoms are composed of negative charged protons and positive charged electrons, I will call this thoery Ashton's thoery of universeal balance.
I thought that we had to explain the diffrence between scientifc law and thoery but I don't see were anyone did this is so confusing
Thomas A.
Tommy,
So you think there is a completely ooposite universe? Would like our dopplegangers be total ooposites of us? Like if you're the nicest and sweetest person, then your opposite would be the meanest and be really rude? That's wierd to think about. Do you think that one day someone, or even you, would be able to find this world(that is if it really exists)?
Scientific Law- Bernoulli's Law of Fluid Dynamics:
"Imagine fluid flowing steadily through a pipe that carries it from the top to the bottom of a hillside. The pressure of the liquid changes along the pipe, and Daniel Bernoulli discovered the law that relates the pressure, flow speed, and height for a fluid flowing in a pipe."
Written as:
v^2/2+gz+p/P=C
where v=fluid velociy
g= acceleration due to gravity
z=height of a point in the fluid
p= pressure
P=fluid density
C= constant

So, Tommy: Are you sating there would be another solar system with a sun and 8 planets just like this one, or that there would be an entire other universe?

Vcitoria's Theory of Domestic Animals:
Dogs and cats who live in the same house don't get along because they both want to dominate the house.

Scientific Law vs. Scientific Theory:
Scientific Laws are widely accepted theories that have been proven correct many times by different people. Scientific theories have not been tested enough times to become a law or they may prove to be incorrect sometimes.
Kohlrausch's Law:
If a salt is dissolved in water, the conductivity of the solution is the sum of two values – one depending on the positive ions and the other on the negative ions.
So basically, the ability of water to conduct electricity, heat, or sound depends on the amount of cations or anions present.
Megan McGowan's Theory of Opposite Motion:
It's impossible to turn your hand in a clockwise motion while turning your foot in a counter-clockwise motion, or vice versa. Your brain can't function in two different directions at once.
To Arturo Antelmo Corrales Garcia:
So if there isn't any gravitational pull in our solar system, how would you explain the different moon's attractions to their planets? For example what causes the attraction between our moon and Earth?
Bernoulli's Principle-(In my own words refering to flight.)Basically a plane flys because the pressure on the top of the wing is moving faster than the air on the lower part of the wing becuase of the way the wing is engineered with the slight curve, the pressure on the top of the wing is therefore lower than the pressure below the wing which generates a lift force.-Kevin Grier
Scientific Theory- Life began when all the needed compounds to create life were smashed into each other and that pile of compounds was then struck by lightning.-Kevin
To Arturo I like the way you think, however why would venus and mecury be satisfied with having such poor conditions and having little to no atmosphere to support any kind of life nat all?-kevin
To Kyle: Yes, that is exactly what I am saying.
To Zach: My freshman year I had about two papers that i turned in late, yet i got full credit...My theory is that my charm with teachers can very much disprove your theory.
-Arturo Antelmo Corrales Garcia
To Zach:No our counter parts from the other universe wouldn't be our doppleganger or oppisite but instead they in all reality would be us in every way and form, in this universe everything is the same as ours, everything except for the make up of its atoms. However i also believe that there could be many universes that exist on ours if your interested in this my basis to this are from Albert Enstiens "String Theory" so if your wondering anymore that would be what to look up.
My scientific theory is what you watch on TV affects your mind. For example, when kids watch violence on TV they become immune to it. You see them watch it all the time and not even flinch.
-Maggie
To Victoria.
I totally agree with your theory.
My dog will go and try to push my cat around all the time when she's near me trying to get her away from me. Probably to try to be dominate like you said.
-maggie
Heres a good theory.
What if the planets motions around the sun are controlled not by gravity but my their relative energies. Think electrons.
what if our solar system is actually an atom and our galaxy a molecule, all forming parts of a larger compound /organism/whatever and that whatever is forming a larger whatever and so in and so forth.
Hooke's Law of Elasticity
Hooke’s Law of Elasticity states that if an object, such a spring, is elongated by some distance x, then the restoring force F exerted by the object is proportional to x:
F= -kx
The k is a constant called the spring constant if the object is a spring.
