TEACHING SCIENCE IN SECONDARY SCHOOLS


 The science teacher should remember that he is legally respon-
sible for the safety of the students in the laboratory; therefore,
he should be present at all times to give counsel and advice. Stu-
dents cannot be urged too strongly to follow directions care-
fully.
 Various expedients may be used by teachers who find them-
selves with large classes. One suggested way to handle these is
to divide them into groups with a leader for each group. The
leader may be responsible for his group and may take care of
much routine work. Select dependable laboratory assistants
for detailed services. Resort to demonstration-experiments
more frequently than normal.
 Additional details on laboratory and classroom procedures
are given in the sections of this bulletin that concern the special
subjects.

 SECTION 9. THE EQUIPMENT OF THE LABORATORY
 This bulletin will not attempt to give plans for any definite
laboratory but will make general suggestions to aid the teacher
in developing a laboratory under a variety of conditions and
through a wise expenditure of available funds.
