Water Density

Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water

• Because their densities are using gravity to pull down

• Because their densities are heavier or lighter

• Because their mass and volumes are equal 

A bobber floats on the water because it is....

• more dense than the water

• less dense than the water

• the same density as the water

• to show you when you have a bite

• it is more dense than the water

• it is less dense than the water

• it has the same density as the water

• it is light
