Glad you liked it. Another interesting approach could be about the element carbon. For most energy processes including life carbon is involved. It can be as hard as diamonds or as soft as graphite. Plants absorb carbon dioxide, but man's industry pollutes with carbon monoxide. could be a good topic for the contest.
