During the classroom discussion on concept of water, a child responded, "water is not colourless". On enquiring by the teacher, child gave reference of dirty water which he had seen in a drain near his home. A teacher respond to this misconception of the child by:
1
completely discarding this answer
2
asserting that his logic is baseless
3
accept the response and explain the logic of calling the water colourless
4
emphasing on only one correct answer i.e. water is colourless
