Project Budburst is a national network of people monitoring plants as the seasons change. Data is collected in a consistent manner across the country so that scientists can learn more about the responsiveness of plant species to changes in climate locally, regionally, and nationally. The website includes extensive educational resources for implementing the project within various classroom and informal settings.

In this activity, students will investigate tree rings and attempt to figure out what environmental conditions cause differences in the width of rings in a given tree. They will use data to build an argument to support their hypotheses.
