• the ice is more dense than the glass

Which liquid is the least dense?

• water
• syrup 
• plastic bottle

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
