why labs are important in science?

Answer 1

I'm guessing you mean why labs are important in science classes. There are a few reasons:

1) They can be fun.
2) They get students thinking about the things they're learning in a different way. Instead of dry equations on a blackboard, you see what happens when waves interfere, how potential energy actually works, etc. They also often get students asking questions they wouldn't otherwise have thought of.
3) They introduce the idea of error, which is very important in interpreting all kinds of data. You learn that just because your experiment gave you a number, it doesn't mean the number is correct.
4) They train future scientists to do what they'll do every day!

Answer 2

More true in chemistry than in some other sciences.

Chemists do their work in the laboratory. The subject of chemistry requires not only theoretical knowledge, but also practical experience. Teaching lab experiments allows the students to learn how to do the experimentation.

Student labs also give practical observable proof of the theories behind the lectures. Things do not always come out the way you expect. This is why "dry labbing" chemistry experiments is frowned upon with so much force.

If you mean "lab" as in "laboratory", we need labs because they provide dedicated areas for storing chemicals, and storing and seting up special apparatus. It basically a work space. Imagine trying to light a bunsen butner in the middle of the campus lawn and then doing an experiment. Regular environmental conditions (wind, rain, crazy cyclists) alone would make it hard.

If however you mean "labs" as in carefully selected science experiements done in school/university, then their purpose to expose you the practical application of the theories you are learning in class. Experiements help student to understand and learn science and to break up the boredom of teachers/leactures droning on and on.

So when a teacher tells her class that acids turn litmus red and alkalis turns litmus blue, its good to give them some experiments to carry do. Give them some named acids and alkalis to test with litmus. Then some unknow substances to test and let them identify the acids and alkalis. That way they can see for themselves what they have read in the text .

Labs are also a very good way of introducing students to good technique when conducting experiments, particularly saftey rules. There is a correct way to dilute concentrated acids for example. Doing this the wrong way can make you seriously ugly. Labs can also be used to teach the right way to record experiments, results and conclusions, the importance of not forging results etc.

All these basic skills are used by real life scientists when they work. If a scientist can't record his work he can't get credit for it. Imagine developing a cure for AIDS and not being able to get credit for it because you forgot write down the chemicals you mixed together.

When you are researching something new, you often have to build a theory for your observations. Laboratory experiments are the way you test a theory. We also do lab experiemnts to apply theories and create new technologies.

Answer 5

Modern science depends upon experimental observations to test and refine hypotheses. A work area for perfroming experiments is a laboratory.

Done.

Answer 6

Porque en los laboratorios es donde hacen los experimentos, sin ellos no podrian descubrir la gran ciencia que existe... que buena pregunta, te lo dice un argentino.

Because in the laboratories it is where they make the experiments, without them they do not podrian to discover the great science that exists… that good question, you says an Argentinean to it

Answer 7

to test things and make sure the scientest are right

Answer 8

That's where scientist do all their sientific thingys!!
For experiments!!!
