Beginning at the left end of the tape, record each year from the earliest year identified on the tree-ring samples through 1992. After the years are recorded on the strip, identify years that were good growing years for the trees in Pinetown, and years that were poor. Think of other events that might have happened during this time period such as your birthday, Presidential elections, important scientific discoveries, or record-setting sports achievements. Fill them in on the time line. You can color the time line and illustrate it with drawings, photographs, or newspaper clippings.
Extensions Measure the tree rings in the photograph on the back of the poster.
Assume the tree was cut in 1992. Find and map the locations of some of the oldest known trees in your neighborhood. Sketch what you think a core from one of these trees might look like. Contact your local forestry service or science museum and obtain some actual cross sections of trees that have been cut in your area. If a tree has been cut in your neighborhood recently, look at the tree rings on the stump or ask if you can keep a small piece of the trunk.
