Science is a hands-on laboratory class. Students
will be doing many laboratory activities which
require the use of chemicals. Safety in the science
classroom is the #1 priority for students,
teachers, and parents. To ensure a safe science
classroom, a list of rules has been developed and
provided to you. These rules must be followed at
all times.

I have a no tolerance for inappropriate behavior
during a laboratory activity. Students will be
asked once to stop the inappropriate behavior.
The second time it occurs the student will be
asked to stand in the hall until the activity is
complete
