cours de physique chimie 3ème

The chemistry classes at college aim to awaken the scientific spirit, in particular through experimentation and observation. Students discover the principles of scientific reasoning and sharpen their critical thinking skills, their sense of observation, their curiosity for scientific and technical progress.

In third, the chemistry program aims to understand on the one hand the principle of conductivity in materials as well as in aqueous solutions, and on the other hand, to deepen the question of the structure of matter as well as its transformation.
