9451025 Luken Tree-ring chronologies and related activities are used to focus of two newly developed undergraduate laboratories. These chronologies, in the form of cores, represent unique and readily available long-term records of organism/environment interaction. One laboratory for introductory biology requires students to measure a series of tree-rings, relationships between ring-widths, and climatic factors. The concepts of accuracy, precision, and variable identification are also taught. Another laboratory in ecology requires students to measure a series of tree-rings to determine combinations of climatic factors that affect growth over periods of time.

小行星9451025 树木年轮年表和相关活动被用来关注两个新开发的本科实验室。这些核心年表代表了生物体/环境相互作用的独特和容易获得的长期记录。一个生物学入门实验室要求学生测量一系列的树木年轮，年轮宽度之间的关系，以及气候因素。准确度，精度和变量识别的概念也教。另一个生态学实验室要求学生测量一系列的树木年轮，以确定在一段时间内影响生长的气候因素的组合。
