Now Add Water…

February 21, 2008

On the third level of the Tower of Ten, we find exhibits about water at various scales.

The first exhibit you’ll see when you arrive at the top of the stairs is a model of the water molecule, with its central oxygen atom and two hydrogen atoms sticking out at an angle. Interestingly, the water molecule is roughly one nanometre across! To the left of the water molecule are two puffy ice crystal clouds. Cirrus clouds (the wispy ones way way up in the sky) are made of ice crystals.

To the right of the water molecule are some models of snowflakes, which are large intricate ice crystals.

The exhibit on the East side is a set of models of water nanoclusters, which are small groups of water molecules that sometimes form. Different arrangements occur depending on the conditions (e.g. temperature or pressure).
