scientist
I Don't KNOW IM TRYING TO FIGURE IT OUT MY SELF
If ur ten year old brother wants to become a scientist he needs to now everything.
because a scientist needs all his information before making him example or experiment complete and without temp or pressure u never know what could happen
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.
only the tigers know
Because If they don't, the scientists won't know what the difference is in.Example:You have two glasses of water. One is labeled control.The other is labeled salt. The one labeled controlhas nothing added to it. The one labeled salt has salt added to it. Is there a difference between the two glasses?If an experiment has a control in it, that means the scientist needs to know if there is a difference in the experiment.
your answerWell what you have to know FIRST is what they do BEFORE the experiment. What scientist do before an experiment is they observe what they are going to do. Then they come up with an HYPOTHESIS. An HYPOTHESIS is an educated guess. They write what they THINK is going to happen. Then they do their experiment. After they do that, they check their HYPOTHESISand if they guessed wrong, they don't cross the HYPOTHESISout, they learn from their mistakes, so they write what really happened during the experiment.

EXPERIMENT! good luck
Scientist use their data to make charts and GRAPHS to communicate the results of their experiment.
they would know the correct formla
