do so.

Gather your paperwork (science notebook, handouts) and sit in your

assigned seat.

2. Be alert and proceed with caution at all times in the

laboratory. • Report any accident (spill, breakage, etc.) or

injury (cut, burn, etc.) to the instructor immediately, no matter how trivial it may appear.

• Notify the instructor immediately of any unsafe conditions you observe.

• If you or your lab partner is hurt, immediately yell out “Code one, Code one” to get the instructor’s attention.

4. Be prepared for your work in the laboratory.

• Read all procedures thoroughly BEFORE entering the laboratory.

• Carefully follow all instructions, both written and verbal.

• Labels and equipment instructions must be read carefully before use. Set up and use the prescribed apparatus as directed in the laboratory instructions or by your instructor.

Listen carefully during the pre-lab instructions.

• Your teacher will let you know what lab materials are needed and will address specific safety concerns for that specific lab.

• It is important that you listen actively in order to be safe. Students who are not attentive during pre-lab WILL NOT be allowed to conduct the lab.

• Respond immediately to directives from the teacher. If your teacher tells you to do something during lab, do it IMMEDIATELY.
