Abstract
The fixed-point observation of the forest by video and sound has been continued in the university forest in Chichibu, the University of Tokyo since 1995. The purpose of this observation is record and analysis of the forest landscape, and the educational use. To use this forest video archive in the science class, it is necessary to upgrade metadata related to content of the science class. The tree phenology exerted a big influence on the forest landscape. Then, it is tried to upgrade tree phenology information. In this study, it is examined whether teaching materials concerning phenology by the forest video archive apply to the science class in the elementary school. As a result of examination of course of study, it is thought that the class about tree phenology can be done by the fourth grader or more. In this study, the tree phenology of the beech was able to be treated in the sixth grader. In this case, there is a possibility that the video which takes a picture of the near view is effective. Moreover, it is thought that it is preferable to do an enough explanation of the targeted tree phenology before the video teaching material is presented.
