4. Nocturnal Animals • Today we are going to be learning about Nocturnal Animals. Keep your Eagle Eyes open for some clues! • Nocturnal animals are active at night. During the day, these animals sleep or keep away from the sun. • It is not until the sun goes down, that these animals begin to look for water and to hunt for food. • Some nocturnal animals have special features that help them adapt to the dark.

11. Echolocation • Some animals are even equipped with a special adaptation that give them super hearing, such as a bat! • Bats use echolocation to find food! Bats have super sonic hearing. Bats use sound waves to find their food. The sound wave bounces off an insect and tells the bat where to fly!

12. Echolocation Facts • Even if thousands of bats are using their echolocation at the same time, they can still fly and find food. • Humans can’t hear the echolocation sounds. • Most of the time bats use their mouth to send out echolocation sounds, sometimes they use their nose. Class Echolocation Activities • Today we will watch a video on echolocation. • Later on we will also participate in an echolocation activity to better understand how echolocation works.
