Lesson Overview
About this worksheet
Some animals are awake when we are asleep. A nocturnal animal is active at night and sleeps by day, often with large eyes or sharp hearing to help in the dark, while a diurnal animal is active during the day and sleeps at night. This worksheet helps young students sort animals into these two groups.
Section A on page 1 gives eight animals – an owl, a butterfly, a raccoon, a firefly, and more – and asks students to write nocturnal or diurnal for each. The reference box teaches the idea with a bat and a honeybee, which are not used in any item.
Section B on page 2 asks what nocturnal and diurnal mean, names an owl body part that helps in the dark, and asks whether people are nocturnal or diurnal. Page 3 is a complete answer key with sample answers. The skill connects to animal adaptations and habitats.
How to Use This Lesson
Read the reference box aloud and ask students when they are awake and asleep.
Complete Section A independently – have students ask ‘is this animal out at night or in the day?’
Discuss the special traits nocturnal animals have, like big eyes and sharp hearing.
Use the answer key on page 3 for self-check.
Pair with the Animal Adaptations Worksheet or the Animal Habitats Worksheet.
