Citizen science programs involve students and teachers contributing to ongoing scientific work. Sign up to participate in The Smithsonian Institution’s Tree Banding Project and contribute to research about tree biomass, and how trees respond to climate. Students around the globe will monitor the rate at which their local trees grow, and learn how that rate corresponds to Smithsonian research, as well as compare their work to other students worldwide. Schools will be selected for participation based on location and when they apply. If selected, the Smithsonian will mail a kit that includes everything students will need to get started.
