These physical environments were the results of hundreds of millions of years of change. This is the second area of emphasis. The how and why of the geological changes of the past three hundred fifty million years that have resulted in the Connecticut we know today is presented. It is an active and fascinating geological history that we find when studying Connecticut. In New Haven we find rock of the lost continent of Avalonia that is some six hundred million years old. To the East and West of our city is four hundred year old sea bed of the Iapetos Ocean and in the middle of our city the two hundred million year old lava deposits of East and West Rocks. The unit includes lessons on rocks and minerals and a lesson on approaches to use in teaching the concept of time at these grade levels.
