Things needed:
1. Small paper cup
2. Enough crushed ice to fill the cup
Step 1: Fill a paper cup completely full of crushed. Set the cup aside in a warm place.
Step 2: Wait for the ice in the cup to melt Is the cup full of water?
Why does ice float?
Science & Environmental Facts : Why Does Ice Float?
Ice floats in water because when water is frozen, it expands and gets less dense. Anything that is less dense will float on a more dense material, such as water. Learn how Archimedes's Principle explains the rules of density with information from a math and science teacher in this free video science lesson.
As an ice cube melts, its volume changes, but its weight is conserved (law of conservation of mass). So, the melted water has exactly the same weight as the water it displaced as an ice cube the water level stays the same! Ever wonder what would happen if the water is salt water and the melting ice cube is fresh water? Try it and see
