Bill Nye: Buoyancy

What principle explains why objects float or sink in water?

• Friction

• Magnetism

• Buoyancy

• Gravity

What happens when a boat is placed in water?

• It creates waves

• It absorbs water

• It displaces a volume of water

• It dissolves in water

What is demonstrated by the model boat of science in the experiments?

• Water pollution

• Water displacement

• Water evaporation

• Water condensation

What principle is demonstrated when a boat displaces water in a tank?

• Buoyancy

• Thermal expansion

• Magnetic force

• Gravitational pull

How can the weight of displaced water be demonstrated?

• Using a barometer

• Measuring with a thermometer

• Using a scale and weights

• Observing color changes

What determines if a metal boat floats?

• The weight of the boat

• The shape of the boat

• The temperature of the water

• The color of the boat

How does the shape of an object affect its buoyancy?

• Shape can determine how water is displaced

• Shape affects only the color, not buoyancy

• Only the size matters, not the shape

• Irrelevant to buoyancy

Why does an aluminum foil boat float?

• Because it's made of metal

• Because it's light

• Because of its shape

• Because it's painted

Who discovered the principle of displacement?

• Newton

• Einstein

• Galileo

• Archimedes

What did Archimedes shout when he discovered the principle of displacement?

• Eureka!

• I got it!

• Amazing!

• It works!
