TEACHING SCIENCE IN SECONDARY SCHOOLS CHEMISTRY IS WELL ADVERTISED SECTION 6. THE TEACHING OF CHEMISTRY Chemistry is already well advertised to the students who en- roll in the subject's classes. Its wonders have been emphasized- indeed, glamorized-through the newspapers, magazines, and even the "comics." The chemistry teacher's obligation is to direct this preliminary interest into the channels of true science and to sustain it through the school year. As is true with other sciences in the secondary school, the main purpose of chemistry instruction is to present the simpler, more fundamental principles in such a manner that the environ- ment may be better understood, and an appreciation of chem- istry's contribution to civilization developed. The laboratory should give such insight into the value of direct evidence as to impress the student with experiment as fundamental to the scientific method. Applications of chemistry should be those the student meets in person, rather than those of theoretical sig- nificance only. College professors often contend that high school chemistry does not give that advance information which would be helpful to a student in college chemistry. Teachers of the subject should not be troubled by this criticism. It is not founded on any clear
