Warning: NOT FOR THE WEAK HEARTED!
Sometimes i can vomit blood correcting these children.
Yet, they're so innocent I can't help but adore them for
the mistakes they made.
bi) He noticed that his fish tend to swim near the surface of the water. Why?
To get more oxygen from the surrounding since the water in the aquarium has limited air supply.
bii) Suggest two ways Ben can improve the condition of his fish tank, so that his fishes need not swim to the surface of the water constantly.
He can add some water plants and an air pump to his aquarium so as to supple more oxygen in the water.
See what I mean when i say i love and hate them at the same time?
These children... ... :)
