What Are the Functions of the Five Senses?
Eyes obviously allow us to see. But if you break it down, they do more than just that. Using our eyes,
we can judge depth, interpret new information, and identify color (the wavelengths of light that reflect off
surfaces).
Noses are used to smell scents. They get a sense for what particles are traveling through the air, which
can help us identify if dangerous chemicals are nearby. Smell also has the strongest connection to
memory; a familiar smell can remind us of things long forgotten.
Ears allow us to hear sound - to detect vibrations in the air particles around us. But the inner ear also
helps us maintain balance and regulate sinus pressure. This is especially useful when you change
altitude (like, for example, when you are flying in an airplane).
Tongues are used to taste foods, allowing us to figure out if something is going to be useful to our
bodies or poisonous. They also allow us to sense hot and cold in food and liquids.
Last of all is the skin, which is responsible for what may be the most important senses in the human
body. The skin performs a huge number of functions. These include:
•
Perspiration (sweating) to cool the body
•
Protection from the element

Topic: gas state (1hour)
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure
gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from
one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon
dioxide).
