Organism: a living thing that can be small like bacteria or large like an elephant.
You wake up, but stay in bed for a moment, sensing the world around you. You feel your muscles pull as you stretch under the soft covers and slowly open your eyes. You might see light coming in through the blinds, hear a car honk outside, smell someone cooking breakfast, or taste dry toothpaste on your lips from brushing your teeth the night before.
As a living organism, it’s important for you to be able to sense and respond to the environment around you. Humans and many other animals have five main senses that help them understand the world around them. How do each of these senses work, and what happens when they don’t work properly?
