Resource Description
CLIMATE CHANGE, FOREST CHANGE, AND TREE RING ANALYSIS DISCOVERY KIT. Acorn Naturalists. Tree rings give us insight into climatic conditions and patterns. Scientists have collected evidence that certain regions are experiencing shifts in climate (as seen in increased frequency and intensity of storm events in some regions and drought in other areas). These weather patterns are reflected in tree growth. In the Southwest, for example, trees that are not receiving adequate water are growing more slowly, resulting in tighter growth rings. Different species show different reactions to climate change. While droughts have weakened trees’ resistance to bark beetles in the Southwest, causing massive die-off, coast redwoods in Northern California are growing more quickly due to rising temperatures.

This kit contains five tree rounds from each of five different species: juniper (tight rings typical of plants growing in arid areas), ponderosa pine (typical of conifers growing in areas with regular wet/dry seasons), sassafras (typical of plants growing in areas with longer annual wet and dry cycles), birch (light, poorly defined rings typical of trees growing under moist conditions), and oak (classic defined rings with ray pattern). In addition to the 25 tree rounds, the kit also contains five 3x pocket magnifiers for reading rings, and this booklet. All of the tree rounds, collected from branch trimmings, are oven dried and sanded on one side to make it easier to read the rings. Ages 7-12. #KIT-22151.
