Science Experiments

It depends on what kind of experiments you're talking about.

Animal behavior experiments are generally done in order to understand why they behave the way they do, and by extension to help us understand why humans behave the way they do.

Drug trials are done on animals first in order to see if the treatment is a) effective and b) safe. Each species has its own metabolic quirks, so a treatment that is safe and effective in animals MAY not be so in humans, but it's a way to identify treatments that are at least POTENTIALLY safe and effective for humans.

Finally, some testing is done for teaching/training purposes. A school may have students experiment on, say, rats even though the expected results are known, in order to train the students how to perform experiments in which the results are NOT known.

Plus rats, mice, dogs,primates and cats all get used for expiriments. You may think-ew mice, rats, who cares about them? BUT THEY HAVE A LIFE TO YOU KNOW AND THEY WANT TO LIVE IT!

Controls are the things you leave the same when you do an experiment. Variables are the things you affect in an experiment to see if it makes a difference. It depends on the experiment how you would "control" the variable.

To find out what the rules and regulations in the lab, you have to type in Wikianswers 'You want to know the worlds most famous person?' I have written all about this one...

No inventors invent stuff and scientist study stuff. Scientists perform experience to see what the answer would be, inventers will find a new purpose with current materials and technology.

He did a lot of important work with microscopes and telescopes, as well as forging money, so he certainly had an education. He may have educated himself, of course, which is sometimes more useful than going to school.

To ensure your first trial was accurate

Losses are due to inefficencies of the motor, and friction on moving parts.

it was discovered in Philadelphia Pennsylvania in so told 1762

Friction is the force produced when two objects are rubbed. Rough surfaces exhibit more friction while smoother surfaces tend to be almost frictionless.

economic theory states that there is no such thing a a free lunch. the reason for this is someone has to pay for that sandwich that you are about to eat for "free." someone produced and payed for the bread and meat in the sandwich, then it is bought by stores, then the place that made you the sandwich had to buy those meats, and now you get to eat that sandwich that cost you nothing but it cost other people money.

A superstition is any belief that is followed based on tradition and empirical evidence rather than a belief that is based on scientific testing, logic and reason: Any belief that relies on the existence of something supernatural for an explanation, it is a superstition.

Space itself is huge, but the sun is the biggest planet, but being that there are actually other things believed to be in space; there may be something even bigger and better. Pack your things, throw on your suit and life off on the count of 3 & you shall see.

The Instinctive Theory of the Origin of State suggests that the state emerged naturally from the instinctive human need for social organization and cooperation. This theory posits that people formed states to fulfill their inherent instincts for safety, security, and social order. It argues that the state is a product of humanity's evolutionary predisposition towards living in groups and developing systems of governance.

Yes, unfortunately they did just about anything you can think of to kill a Jew. Jews were like rats to them, they were non-human to Nazis and if the Nazis wanted to test something, they would use a Jew.

they are same because they are part of the water cycle and they are different because evaporation is the process by which water changing to gas but condensation is the process by which gas changing into water.

Plastic pollution not only affects the bodies of water around us, but the land , too. Examples on how not to pollute, is try to reuse cups and bottles of water, or using matches instead of lighters. A few more basic suggestions is always prefer paper over plastic , try not to use plastic silverware, or straws.

Noise pollution is a type of energy pollution in which distracting, irritating, or damaging sounds are freely audible. As with other forms of energy pollution (such as heat and lightpollution), noise pollution contaminants are not physical particles, but rather waves that interfere with naturally-occurring waves of a similar type in the same environment.

Most of the time they write down what they are going to do, what they think will happen judging on what they are using. Then they go from there

remove as much space touching the surface which will cause friction.

Yes there is an actual place in Nevada called Area 51.

Wilson was President during the First World War 1914-1918, and he died in 1924. It was Harry Truman who was the President when the Atom Bomb was first used in 1945; it had been developed during the administration of Franklin D. Roosevelt and Truman authorized its use on Japan in 1945, during World War Two 1939-1945. Wilson created an organization of researchers and scientists (The National Research Council) and tasked them with working on such things as improvement of US weapons. Roosevelt and Truman too had a similar organizations of scientists and researchers (The National Defense Research Committee), and they were working on making military weapons more effective and the Office of Scientific Research and Development (OSRD) that helped develop the Atomic bomb

poo on you poo on you i put my but on your face and poo on you everybody get down and let me show you some brown.
