That is an epistemplogical issue. When our students has scientific
problem like How the water expands when is freeze? they are facing one
knowledge problem: how you know this is a matter of fact that ALL
substances contract when it is freeze. That's mean that you have the
certainity that every substance contract it, etc. You need faith and no
reason to accept some scientific conclusion if in your class time you
present scientific knowledge based in hard evidence. The proccess to
construct or build knoledge implies to rebuild the scientist process to
explain phenomena and the students must reflect about the nature of their
reason evidences and convince themselves about the certitude of their
knowledges.

Excuse me for this lack in english expression.
