Science Primary 1 – Float & Sink
Posted September 12, 2015on:
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.
“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.”
