The Changing Earth

               As all science teachers know the earth is constantly changing but usually at a pace that is very small and not very discernable, unless a major physical event happens.  Major events have been happening with more frequency lately than we would normally expect or want.  Is the world in turmoil or is it just an evolutionary geological cycle in the natural order of things?  This controversy goes on and on by the world’s leading scientists and environmentalists and we know that things are changing but can we intervene in the right way is the big question.  We seem to be gaining on our understanding but we aren’t quite there yet.  Here is a science project geared for middle school aged children that could help to spark some interest in earth science.  Richard.
