When writing up lab exercises, students must report on "cause of error." Now a mistake is not an error. "we poured too much in..." Well do it again. "We made a math error..." go back and check your math.
An error is something keeping you from getting the accepted results that no matter how careful you are, you have no control over.
such things are
Human error in making measurements, "measure twice cut once" anybody?
Two people can measure with a ruler and get close measurements but not the same...the eye can see different things.
"the chemicals may be old." Well guys this is fine...I'm cleaning out the stuff from the last teacher and no telling how long some of those chemicals have been in there.
Today I got a doozey of an error.
"Disfunctional lab group." Erum...I can't argue with that. Groups of teenagers with their drama problems.
Though I did suggest to the student part of lab groups is to help the other people.
