Float and Sink

Which one will float in water?

• 
• 

Which one will sink in water.

• 
• 

Explain what density means in relation to objects floating or sinking.

• Density is the color of an object

• Density is the speed of an object

• Density is the mass of an object per unit volume. Objects with higher density than the fluid they are in will sink, while objects with lower density will float.

• Density is the temperature of an object

How does buoyancy help objects float in water?

• Buoyancy creates a magnetic force in water

• Buoyancy helps objects float in water by exerting an upward force that opposes the weight of the object.

• Buoyancy generates heat in water

• Buoyancy pulls objects down in water

Name a material that typically floats in water.

• Metal

• Wood

• Glass

• Plastic

Name a material that typically sinks in water.

• Aluminum

• Iron

• Plastic

• Wood

Why do some objects float while others sink?

• The color of the object determines if it floats or sinks.

• Objects float based on their shape alone.

• Density comparison with the surrounding fluid determines whether an object floats or sinks.

• Objects sink due to their temperature.

What happens to the water displaced by a floating object?

• It becomes denser.

• It is equal in volume to the object's submerged volume.

• It disappears completely.

• It turns into steam.

Describe an experiment to test if an object will float or sink in water.

• The experiment requires heating the water to test if the object floats or sinks.

• The experiment involves measuring the object's weight to determine if it will float or sink in water.

• The experiment involves throwing the object into the water to see if it floats or sinks.

• The experiment involves placing the object in water and observing if it floats or sinks based on its density compared to water.

How can you change the density of an object to make it float instead of sink?

• Increase the density of the object

• Keep the density of the object the same

• Change the color of the object

• Decrease the density of the object
