Calcium oxidizes when combined with water. If you were to pour calcium powder into a beaker of water, you would see a much more dramatic effect, as the increased surface area of the powder catalyses the reaction. Also, calcium pellets (resembling gravel) react similarly with water, oxidizing and bubbling, and raising the temperature of the water. Your calcium samples must have been small enough to float to the surface on the gaseous bubbles created during the oxidation, and sank to the bottom once again after the bubbles were released.

How does the limestone cycle work?
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
