Model Earth

Mr. Hamilton's classes made a different color play dough for each layer of the interior earth:pink for the inner core, orange for the outer core, yellow for the mantle. blue for the crust. A different  orange layer for the South American plate with South America was represented by yellow. Each layer of the core was made by determining the scale needed to accurately  represent that layer in the model that each student made. We started with a 1/2 inch diameter inner core and worked up to the finished model having a three inch diameter. To finish the project we made a scaled representation of the South American plate with a scaled representation of South America attached to the South American plate. This project took three days in class and many hands to make and shape the play dough.
