2. Do not touch any equipment, supplies, animals, or other materials in the science room without permission from the teacher.

3. Follow all written and

verbal instructions carefully.

4. Perform only authorized and approved experiments. Do not conduct any experiments when the teacher is out of the room

5. Never eat, drink, chew gum, or taste anything in the science room.

6. Wear safety glasses or

goggles when instructed.

7. Dress properly—long hair must be tied back, no dangling jewelry, and no loose or baggy clothing. Wear aprons when instructed. Closed Toe Shoes Only!

8. Learn where the safety equipment is located and how to use it.

15. Never Work Alone in the Lab

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
