Students studying plants will collect and contribute data to the US National Phenology Network through their citizen science project, Nature's Notebook. Phenology is nature’s calendar—when cherry trees bloom, when a robin builds its nest and when leaves turn color in the fall. The US National Phenology Network analyzes the timing of these annual events in the context of weather events and seasonal changes. This project involves a study of the different phases of trees by monitoring select trees in your schoolyard and recording when they flower, fruit, drop leaves, etc. Students will have access to dynamic maps and graphs?
