Challenge 4:

The Constellations

Who has never contemplated the sky around a fire or lying on the grass? What we see up there are the constellations. Constellations have always been an important landmark for travelers, on land or at sea. Did you know that they differ from one hemisphere to another? For this last challenge, observe the stars and try to identify the constellations visible where you live!

Watch the video, and listen carefully to the instructions.
