NB11 - Night and Day

Many animals are sleeping while you are active during the day, they wake up when the sun goes down and you go to sleep. The eyes of the owls get bigger and the pupils widen in the dark, and the wide pupils help them to collect more light to be able to see in a dark forest. Around 20 March and 23 September, daytime and nighttime are of approximately equal duration. When there is a full moon, the moon goes down when the sun comes up, it comes up again when the sun goes down. Although the Sun appears to "rise" from the horizon in the East, it is actually the Earth's rotation around its own axis that causes the Sun to appear and move across the sky.
