Description
Students are provided with a set of four paper strips with pre-marked tree cores from four different trees. They align the four samples so that the rings match. Students then answer a set of questions about the life span of the trees, good and bad growth years, and the length of the climate record they have constructed.
This activity is presented by the Univeristy Corporation for Atmospheric Research.
