Life on Earth

Life on Earth aims to advance (1) public understanding of the history of life on Earth and biodiversity, and (2) our knowledge of how people interact and learn from large interactive science data visualizations on multi-touch displays in public settings. Our multi-institutional project team has developed the DeepTree, the FloTree, and Build-A-Tree (BAT). The focal exhibit, called the DeepTree, utilizing large data sets from four online databases including Tree of Life web project (www.tolweb.org), Encyclopedia of Life (www.eol.org), National Center for Biotechnology Information (https://www.ncbi.nlm.nih.gov/) and Time Tree (www.timetree.org), allow museum visitors to explore the relationships of 70,000 species, spanning over 3.5 billion years of evolutionary history using touch gestures on a large multi-touch computer display. Embedded inside the DeepTree, the "FloTree" encourages exploration of evolutionary processes within a single population. "Build-a-Tree" (BAT) is a multi-level phylogenetic tree-building game. These learning experiences are designed to target core evolutionary concepts and be self-directed, physically interactive, embodied, and collaborative. The Life on Earth exhibit has been installed at California Academy of Sciences in San Francisco, the Field Museum in Chicago, University of Nebraska State Museum in Lincoln Nebraska, and Harvard Museum of Natural in Cambridge Massachusetts. Please visit the Life on Earth website at https://lifeonearth.seas.harvard.edu/ to find more details on publications, and the ongoing learning research and summative evaluation. The Life on Earth project brings together a team of interdisciplinary researchers in human-computer interaction and information visualization, learning sciences, museum exhibit design, cognitive and developmental psychology, and evolutionary biology.
