The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.

  • Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.
  • Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.
  • Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.

Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.
