Welcome to Drug Scene Investigators (DSI)
DSI is an online library based game developed by inDepthLearning, a 501(c)(3) charitable organization, with teachers and substance abuse experts for use in 7th – 10th grade health & science classrooms.
Students use scientific inquiry (National Science Educational Standards: Content Standard A, Science as Inquiry) by engaging in true-to-life drug related mysteries while learning about the science behind alcohol, tobacco, inhalants and other drugs — all while having fun!
