Glue the Safety Cartoon into your notebook after your notes– Identify the

students who are breaking a safety rule. Then list the name of the student and

the rule that is being broken. If it is not one

from our notes but you think a rule is being

broken write it down!

MODELS

Used to demonstrate items that

can not be easily attained or

seen. Some things just won’t

work in the classroom.

MODELS Benefits – allow us to view and examine items

hands on that we would not normally be able to

have access to.

Limitations – Models do not have the detail of the

real thing – their purpose is to help us get a

general overview not a detailed look.

MSDS – Material Data Safety Sheet

Used to describe safety hazards of

specific chemicals
