Discussion Ideas

Before watching the video:

After the video:

  • Discuss: Even though a planet is located in a “habitable zone” or had water at some point in the past, does that automatically mean we should expect to find life on it? Why or why not?
  • Activity: Download the free “Exoplanet” app from iTunes. Explore the variety of planets currently known to scientists. Note their differences in size, density, and other parameters.
