What is the iScience program?

iScience is DLiA’s schoolyard biodiversity program in cooperation with the Tennessee Valley Authority (TVA). The program aims to increase awareness of and appreciation for the incredible biodiversity around us, as well as foster young people’s interest in STEM fields. This program uses the ATBI (All Taxa Biodiversity Inventory) model, bringing ATBIs to schoolyards in Tennessee. Students conduct ATBIs at their schools using iNaturalist, acting as citizen scientists and collecting real scientific data about their local biodiversity.
