  1. Voyages Through Time

    Voyages Through Time (VTT) is an integrated science curriculum for ninth or tenth grade based on the theme of evolution and delivered on CD-ROM. It’s six modules span the breadth of astrobiology research, from cosmic evolution through the evolution of life, and beyond. In VTT, evolution is defined as cumulative change over time that occurs in all realms of the natural world. The evolutionary scope of VTT is billions of years long and ranges from the Big Bang to modern technologies.

    The overarching goals for VTT are for students to understand:

    Evolution as cumulative changes over time;
    The various processes underlying these changes;
    The differing time scales and rates of change;
    The connections and relationships across these realms of change;
    Science as a process for advancing our understanding of the natural world.
