THE IMPORTANCE OF DEMONSTRATION EXPERIENCE AT LESSONS OF CHEMISTRY

The article is devoted to the analysis of the significance of demonstration experiments in chemistry lessons, because teaching of chemistry at school can't be successful without organizing corresponding experi- ments, which are an important condition for motivating students' cognitive activity and training a steady interest in the studying subject. The author believes demonstration experiments are necessary for consolidation theoreti- cal knowledge, since visual memory is more operative than auditory memory, and thought processes have a close connection with visualization of knowledge and visual memory.
