Chemistry concepts come alive against the backdrop of the Sochi Olympic Winter Games! Here is a captivating clip to share with your chemistry kids. It teaches how the bonds in a water molecule contribute to the formation of a lattice within a chunk of ice, and how their lack of bonding at the surface provides the slipperiness that makes Olympic ice skaters really move! Pupils also learn how salt molecules are used to keep water molecules apart, preventing them from bonding to become ice. This would be a neat addition to your chemistry curriculum when covering the any of the following topics: hydrogen bonds, crystal lattices, ions, or freezing point.
