Signs of Life

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features. Learners also identify any biological features, such as presence of water or vegetation, that could be used as evidence of life. Then learners look at photos of the surfaces of Mars and of Jupiter's moon Europa and compare them with photos of Earth to determine what geological features on these two worlds are similar to Earth's, and which are not. This activity can be found on pages 8-9 of the activity guide.
