So you do not get any harmful chemicals in your eyes that could make you blind. Also to protect your eyes from other dangers that creep in the lab.
You wear safety goggles to protect your eyes in case of fumes, splashing, or an explosion.
So things (chemicals and the like) don't get into your eyes.
so chemicals don't burn your eyes
Eyes are difficult to replace.
The purpose is the protection of eyes.
Data
You can do this at home if you want to It is very important to control variables in an experiment because if just one small detail is overlooked, it can end up in a result that is way different from the correct result. Say you had a beaker of a liquid that you were supposed to boil in an experiment to make sure it's completely gone, but you only brought it up to a temperature that allowed a little bit of the contents of the beaker to remain. Then, if you used it in another part of the experiment, it could cause a reaction that is completely far from the reaction that would occur if you had done so the right way.
To take observations (for example, while doing a lab report) means to write down details about what is occurring throughout the process of the experiment.
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
Keep his safty goggles on
you wear glasses while you are in a lab because while you are doing the experiment something can go in your eye and hurt you!
so that you don't mess up, and something could go wrong while you'r doing the experiment.
Scientific goggles would be goggles scientists wear while using chemicals or doing something in the lab that they may want to protect their eyes from.
goggles were invented as a way for us to protect our eyes and look fashionable while doing it. http://www.gogglesandglasses.com/index.html
if what ever you are using gets in your eyes you will get blind
how to reduce the problem of random error and systematic error while doing an experiment
Data
Data
Closed toed shoes and goggles(depending what your'e doing)
swimming scuba diving skiing/snowboarding construction work
It is called data I believe.
They record data from their experiment from doing the experiment and record data while they are doing it......................example i am bouncing a ball on a carboard,tile,table and the carpet the cardboard is 8 the tile is 18 the table is 16 and the carpet is 19.
