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.
When magma slowly cools and hardens,
إنه حجر يتشكّل مع كريستالات كبيرة
 .بداخله عندما تبرد الماغما وتتصلّب
Ein Gestein, das sich kristallisiert,
wenn Magma sich langsam abkühlt und erhärtet.
A veces el magna se enfría
y endurece formando cristales.
A veces, el magna se enfría
y se endurece formando cristales.
Quand le magma refroidit et durcit,
Quando il magma vi penetra al suo interno e si indurisce
Uma rocha que forma grandes cristais
dentro quando o magma esfria e endurece.
Внутри неё образуются большие кристаллы,
