The bat is the subject of this four-page 4th grade science fact file, which follows how echolocation lets it hunt at night. It is aligned to NGSS 4-LS1-2. Students draw a bat hunting a flying insect in the dark, then fill a table that traces the information from ears to brain to response. A Did You Know box and a summary comparing bat and human hearing close the sheet. The key gives model answers, including a brown bat that eats about 1,000 mosquitoes in one hour.
4-LS1-2
“Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.”
The fact file table, which follows the standard's own path: the ears receive echoes, the brain processes them, and the bat responds.
Students draw a bat hunting a flying insect in the dark.
Six rows: animal name, special sense, sense organ, information received, brain processing, and response. The key fills them with ears, echoes, and a bat that changes direction to swoop on the insect.
Students write one surprising fact about a bat's senses or how much it eats in a single night.
Students explain why echolocation matters for the bat's survival and how its use of hearing differs from a human's.
Research lesson
Give students books or approved websites about bats before they fill in the table. The Did You Know box rewards the student who reads further.
Model first
Fill in the table together for a person hearing a fire alarm. Students then complete the bat rows alone and use the contrast in their summary.
Second animal
Hand out a blank copy and have students make a fact file for another animal with a special sense.
