Christopher often observes the moon with mum or dad, when the sky is not clouded over. Today, suspended in the sky, a gold disk strongly lights the black night.
Dad draws the various forms of the moon on a paper, which he reuses at each observation. Christopher notices that the moon does not always have the same shape : sometimes it is fully round, sometimes only a crescent is visible.
Christopher is in bed and dad shows him, in a book, big photos of the moon. Dad prepared his boy a surprise. He switches off the light, switches on an electric torch, then lights a globe in the bedroom by changing the pencil of rays orientation. From his bed, Christopher alternately sees a completely lightened disk or only a crescent.
In December 2011, on the 10th, a total lunar eclipse took place. It was partially visible in the Eastern Europe.
