pushes an ice cube to the top of a glass of water

• buoyant force

• density

• a sinking object

• compressed air

If an object is neutrally buoyant it will ________.

• sink

• float

• neither float or sink

• objects cannot be neutrally buoyant...

An object should float in a liquid if...

• Its denser than the liquid

• It's the same density as the liquid

• It's less dense than the liquid

Label the two arrows with the correct force

Why does the Screw SINK in Honey?

• The screw is less dense than the honey

• The screw is more dense than the honey

• the screw has the same density as the honey

What is buoyant force?

• An upward force exerted by fluids on an object.

• An downward force exerted by fluids on an object.
