MIND STRETCHER – LAB SAFETY

Why does a science classroom have different rules than a

math classroom? Why do you think it is important for science students to learn and practice

safe behaviors in the classroom?

Lab SafetyEveryone is Responsible!

Safety is #1• Safety is our number one priority in the

classroom.• Biology is a laboratory classroom and you will be

handling hazardous chemicals and expensive equipment.

• In order to make this happen, a list of rules are in place, and are listed in your student safety contract.

• You must have a contract signed by you AND your parents in order to participate in classroom labs.

• You will also pass a safety quiz (with a score of at least 70%) in order to participate.

• You must follow safety rules at ALL times!
