Understanding Buoyancy and Density with Oranges

What is the first step in the experiment to determine if an orange will float or sink?

• Fill a container with water

• Add salt to the water

• Peel the orange

• Cut the orange in half

Why does the peeled orange sink in water?

• It becomes lighter

• It becomes more dense

• It absorbs water

• It becomes less dense

What concept explains why some objects float and others sink?

• Friction

• Buoyancy

• Gravity

• Magnetism

What force acts upwards on the orange when it is placed in water?

• Gravitational force

• Magnetic force

• Buoyant force

• Frictional force

Why does the orange with the peel float?

• The peel is heavy

• The peel has air pockets

• The peel is dense

• The peel is waterproof
