Science Primary 1 – Float & Sink

Posted on: September 12, 2015

This video explains why an object sink or float. A few experiments are conducted as well, and including answering the question why ship and spoon both are made of iron but ship doesn’t sink.

I am not sure the below are explained in Standard 1 class, but this is reason for sinking or floating.

float

“A bowling ball-size chunk of water weighs around 10 pounds.  As the bowling ball (12 pounds) is heavier than the displaced chunk of water, it has more sinking power.”
