Is anything out there?
In this activity, students consider evidence for life on other planets outside our Solar System. They examine data to decide on the likelihood of life on certain extrasolar planets.
Life on other planets
Will we ever see life on planets outside our Solar System? Professor Denis Sullivan suggests that we may never know for sure.
By the end of this activity, students should be able to:
discuss what ‘life’ is
use data to draw conclusions
understand how hard it is to know if there is life on other planets
communicate ideas to others
know some information about planets in our Solar System.
Hunting for planets
Professor Denis Sullivan explains why we can only detect extrasolar planets indirectly. He outlines the ‘wobble’ method of detecting planets around distant stars.

Intermediate teacher Matt Boucher used the Planet Hunters projest within a year 7/8 unit on light. Read the case study and accompanying unit plan with activities.
In the activity Hunt the planet, students plot graphs of light measurements from stars, searching for dimming that indicates the presence of a planet, and calculate its size.
