Question

A lump of ice will float in water, a stone will sink. Name one other object that will float in water ………………….. and two that will sink ………………………

• A. wood
• B. coin, stones

Answer 1

• Floating and sinking depend on the density of water and the density of an object.
• If the density of an object is less than the density of the water it floats.
• This means that the upthrust of water on an object is greater than the weight of the object.
• If the density of an object is more than the density of the water it sinks.
• This means that the upthrust of water on an object is less than the weight of the object.

Therefore, a lump of ice will float in water, a stone will sink. Name one other object that will float in water wood and two that will sink coins, and stones.
