### In the lessons

In science lessons, animals are grouped by when they are active: diurnal (day), nocturnal (night) and crepuscular (dawn and dusk) — such as rabbits, deer, hedgehogs at dusk, many cats and fireflies. In nature writing and stories, «crepuscular» sets a dim, mysterious mood. Pupils may photograph crepuscular rays («sunbeams» or «God rays»). Phrases: «crepuscular animals», «crepuscular rays», «crepuscular light».
