My DD got in trouble for correcting her teacher over what color blood is UPDATE
She is in 6th grade. They were talking about the human body and blood and the teacher taught the class that blood was blue until it hit oxygen. My DD raised her hand and told her teacher that that was a myth...human blood is always some shade of red and has some oxygen in it at all times
Well the teacher got mad at told her she was wrong and she got written up in her passport. I am going to talk to the teacher about it. My DD was right and unless the teacher tells me she was really rude about it (which I doubt) I dont see why she should get in trouble for having correct information.
UPDATE: I talked to the teacher and the principal. The teacher admitted that my DD was no rude about it just trying to spread the knowledge. She said it was an over reaction and apologized. They took the write up away so now my DD can participate in all of the school activities.
