Science Safety

1. Don’t eat or drink in the science lab.

2. Keep the benches tidy.

3. NEVER pour solids into the sink.

4. When using a Bunsen burner after turning it off, let it cool down before picking it up.

5. Don’t work with broken equipment (eg. test tubes, beakers.) because you may get cut from the equipment but also there might be chemicals in the left in the piece of equipment and that could go into your skin.

Science Safety

6. ALWAYS mop up spills so nobody slips.

7. Make sure all the gas taps are turned off when not in use.

8. DON’T sit on the benches as there may be equipment with chemicals in them and if knocked, they could spill.

9. When you break something, tell the teacher and he/she

will show you how to clean it up.

Science Safety

10. When mixing chemicals in a test tube or beaker NEVER look inside it or it could burn your eyes.

11. Hair must be tied back at all times.

12. When you need help ask the teacher and they’ll help you.

13. Keep your books away from experiments.

Equipment

• A Beaker- is a container for mixing/ stirring/ heating chemicals.

• Tripod- is a stand (with three legs) for putting containers such as a beaker on top of a Bunsen burner if you want to any chemicals in the container, eg: conical flask, beaker, test tube, etc.

• Gauze Mat- supports containers over Bunsen burner while they are heated, spreads heat evenly under the container.

• Heat proof Mat- protects benches from damage, mostly put under Bunsen burners, or times with chemicals.

Equipment

• Retort Stand- used with clamps and boss heads to hold substances at a required height, for eg: the clamp may hold a burette over the beaker then what is in the beaker will get heated by the Bunsen burner.

• Test Tube- container for holding, heating, or mixing small amounts of substance.

• Test Tube Rack- holds test tubes upright.• Conical Flask- container for mixing substances or

collecting filtered substances.

Equipment

• Flat bottom flask- a glass container for holding, mixing and heating chemicals. It is almost round with a flat bottom and long neck.

• Measuring cylinder- used to measure volume accurately• Test Tube Brush- this is for cleaning inside a test tube. It

is a long thin brush. • Bunsen Burner- Heats substances.

Equipment • How to use a Bunsen burner:• Step 1= get a Bunsen burner, place it on

a heatproof mat, and attach the gas pipe firmly to the gas tap. Make sure the air hole on the Bunsen burner is closed.

• Step 2= light the up a match then slowly turn on the gas tap.

• Step3= turning the air vents will change the flame& temperature for example: if the air hole is closed the flame is yellow that means the flame is warm, if the air hole is half opened the flame would be light blue and the temperature of the flame would be hot, and if the air hole is opened the flame is light blue and dark blue this means the flame is very hot.

Equipment

• Step 4= if not using Bunsen burner but still on make sure the air hole is closed so that the flame is yellow and warm.

• Step 5= once finished with Bunsen burner, close the air hole, then blow out the flame, turn off the gas taps and take out the gas pipe.
