In this video, Anthony Brown will explain why animals, like cats, seals, and rats, have whiskers. The main function of whiskers is to sense. Sensing is a method by which animals learn about their surroundings. A cat uses its whiskers when it wants to squeeze through a tight spot or navigate in the dark. Meanwhile, seals use their whiskers for finding food.
This video satisfies the 4-LS1-2 requirement of fourth-grade science proficiency.
