The earth sciences club girls are preparing for their cultural festival. Sakura and Ino, the geology club girls, are conducting a real boring survey on the schoolyard. Meanwhile, Mira, Ao, and Monroe, the astronomy club girls, are working hard to produce a replica of the solar system at Mira's home. Then the day of the festival finally arrives.

With Suzu's help the earth sciences club's geocafe is open for business and all the club members are wearing maid outfits.
It's so much fun to notice the moons are 
moving when you observe them over time.
من الممتع جدّا مشاهدة الأقمار وهي تتحرّك
 .عندما نقوم بمراقبتها مع مرور الوقت
Es macht solchen Spaß zu sehen,
wie sich die Monde mit der Zeit bewegen.
Y ver las lunas en otra posición si lo
observas en otro momento es divertido.
Y ver las lunas en otra posición si lo
observas en otro momento es divertido.
En l’observant régulièrement,
Ed è interessante osservarlo nel tempo
É tão divertido perceber que as luas estão se
movendo, quando se observa ao longo do tempo.
Так интересно замечать перемещения лун,
 пока наблюдаешь за ним.
