Even if they have acquired knowledge through common senses they can’t see how Much this science is a part of their lives. For that, scientific knowledge is important, where scientific and technical knowledge add to the comprehension of nature’s phenomena and products that exist in our day to day lives. The goal of this essay is to evaluate the perception of a group of students about the chemistry subject itself, and their expectations before studying chemistry and what has indeed been built at the high school classes.

When the students, that have already finished the 3 ͬ ͩ year of high school, explain their contact with chemistry, it’s possible to perceive that in general they show having built a scientific chemical knowledge.
