Icebergs

Investigating fractions. Icebergs can tower up to 150m above the water. But, nine-tenths of their mass and three quarters of their height are hidden below the surface of the water. Using ice cubes we tried to look at the fractions above and below the surface.
We also tried to investigate the Archimedes' principle, but Geoff throw away the result!!

Various percentage, decimal and fraction work.
