Sometimes you can forget what the results of your first test was. It's always good to repeat an experiment more than once, so you can be sure that your tests worked correctly. And, because you should be repeating the tests, you'll want to record the results each time, so you can compare them when you're finished. That way, if something goes wrong, the results will show in which test it went wrong. Plus, if you're doing something for a class, I'll bet you anything that the teacher/professor will want it written down somewhere. Hope this helps!
Because it is pointless doing an experiment if you are not going to be exact !
So that you are NEVER confused at anytime within the conduction of the experiment.
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
so others can repeat it and see if you did it right
So there exists a record of your experiment that others, or yourself later on, can refer to.
because it is stupid
if you could only record a single temperature reading in a freezing point determination experiment, which temperature should you record

why is it important to identify errors in an experiment
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.
No redo the experiment.
Record your observations during an experiment. This will be part of the data you collect.
