Laboratory.
Some of the things that happened were recorded below:
The class were waiting for nearly 10 minutes but the teacher did not show up so the class prefect opened
the door and they all took off their shoes outside and went inside.
Group 1:
‘Ofa and Sanft lit their bunsen burner then they went to the front of the room to weigh out the correct
amount of salt.
Group 2:
Nafe was sitting on the bench stirring the salt into the water with a glass stirring rod. The glass rod slipped
and broke, so Nafe ran to the front of the room to put the larger pieces into the rubbish box. Some smaller
pieces of glass fell into the sink but Nafe didn't worry about these as he thought they would wash away.
Melania was Nafe's work partner. Melania didn't see Nafe break the stirring rod because she was busy
putting out a fire. Sanft's book caught fire because it was left too close to their bunsen burner.
Group 3:
Masina and her partner Siua were busy heating their test tube full of the mixture of salt and water.
List five (5) separate safety rules that were being broken in this laboratory. (5)
