1. Laboratory Safety & Laboratory Equipment

2. Appropriate Student Behavior
Never Eat in the Laboratory
No running
No horseplay
No unauthorized experimentation
Never, under any circumstance, look directly into the sun
It is not safe to eat anywhere in the laboratory
There could be trace residues of poisonous chemicals that could cause you to become ill.

3. Proper Attire Electrical Outlets
When working in the laboratory students should wear appropriate items for that lab - goggles, aprons, rubber gloves, etc.
Do not wear baggy clothes, long necklaces, open-toed shoes, sweatshirts with drawstrings
Tie back long hair.
Electrical outlets near water sources must be GFI outlets
GFI - ground fault interrupter – current is interrupted to prevent electrical shock.
Always check for rips in electrical cords before the lab begins, report any frayed wires to the teacher (replaced or fixed by teacher)
When removing a plug from the outlet, grab the plug not the cord.

4. Accidents Most accidents can be prevented if you make safety a habit.
The best way to prevent an accident is to keep your work station clean
Reading all parts and directions of a lab before beginning will prevent:
mixing the wrong things together
using the wrong equipment
Never work alone
If you get something in your eyes – wash eyes from the inside toward the outside.
If you get acid on your hands, notify the teacher and quickly rinse for several minutes with water.

5. Science Classroom Requirements
Two exits (windows don’t count)
Fire extinguisher – point toward the base of fire
Fire blanket
Eye wash station

6. Laboratory Equipment Very Important
Know lab equipment and its capabilities so you can carry out the lab in an organized fashion
Gather all equipment prior to beginning the lab to minimize travel during the experiment

7. used to mix, store, or heat solutions or other liquids.
Laboratory Equipment
Beaker
Holds larger amounts of substance – not used to make accurate measurements
Erlenmeyer Flask
used to mix, store, or heat solutions or other liquids.

8. Test Tubes, Test Tube Rack & Test Tube Holder
Laboratory Equipment cm
Metric Ruler
Used to measure length units – m, cm, etc
Test Tubes, Test Tube Rack & Test Tube Holder

9. used to measure liquid volume - in milliliters (mL)
Laboratory Equipment
Graduated Cylinder
used to measure liquid volume - in milliliters (mL)
cylinder guard
Put on the top of the cylinder to prevent it from breaking if tipped over.

10. Laboratory Equipment Used to measure mass – in grams
Add numbers from all three beams to get total mass.
Triple Beam Balance
Used to measure mass – in grams

11. Evacuation Procedures
Fire Alarm – evacuate building based on classroom location
Once outside, find your teacher immediately for check off
Remain outside until informed by teacher to re-enter building
Code Red Procedures
Remain quiet and calm & listen to teacher instructions
Remain quiet until teacher tells you otherwise.
No cell phone use
If caught in hallway – enter closest classroom or hide in bathroom…use good judgement

12. Tornado Procedure
Stay with the class and proceed to the hallway where teacher directs you to go.
Sit facing the wall - quietly so you can hear further instructions.
In the event of a true storm, tuck your head between your knees and cover your head with your hands.
