With great excitement we investigated what happened to the water balloons that had spent the night in the freezer.

Some of the balloons were completely filled with ice but, others were part ice part water. This happened if the balloons had been filled with a lot of water.

We cut away the balloons and inside was ice in the shape of the balloon. It was exciting to investigate and observe the ice. There were lots of bubbles and interesting cracks and holes.

As we were doing our investigating the ice was melting with the heat in our classroom.

So, the liquid water had turned to ice then melted back to liquid water again.
