Selection 6 - Les astéroïdes : présentent-ils un danger réel ou imaginaire?

With all of the latest sci-fi films on asteroids and meteorites, this selection is very relevant. Students read about bogus reports of asteroids that are threatening our planet as well as stories of real-life asteroids that managed to break through our atmosphere and crash into the Earth.
