Safety Considerations

STAGE 1 (Experiment: 30 - 40 minutes)

• Each team carries out the experiment together.
• Each member must wear protective glasses, a lab coat, and gloves.
• All girls must tie their hair. Otherwise, they shall not be allowed to do the practical quiz.
• Each team shall follow the method as listed in the instruction sheet.
• The teacher shall not entertain all questions during the experiment.
