            Skin and touch
          
        
        
          Nerves in your skin
        
        
          tell you if things feel
        
        
          hard, soft, hot, or cold.
        
        
          They also warn you of
        
        
          danger by making
        
        
          you feel pain.

            Eyes and seeing
          
        
        
          Your eyes have special nerves
        
        
          that pick up light. They send
        
        
          messages to your brain, telling
        
        
          you what you are looking at.
        
        
          
            Ears and hearing
          
        
        
          Your ears catch sounds and send
        
        
          them deep inside your head.
        
        
          Nerves send messages about
        
        
          the sounds to your brain.
        
        
          
            Nose and smelling
          
        
        
          Nerves inside your nose
        
        
          tell you what you are
        
        
          smelling. Some things,
        
        
          such as this rose,
        
        
          smell nice. Other
        
        
          things smell terrible!
        
        
          
            Tongue and tasting
          
        
        
          You taste with your tongue.
        
        
          It is covered with tiny
        
        
          bumps, called taste buds,
        
        
          which pick up tastes
        
        
          from your food.
        
        
          
            Your senses
          
        
        
          You know what is happening
        
        
          around you by seeing,
        
        
          hearing, smelling, tasting,
        
        
          and touching things. These
        
        
          are called your senses.
        
        
          Your eyes see
        
        
          the pictures,
        
        
          then your
        
        
          brain tells
        
        
          you what
        
        
          they are.
        
        
          Your ears pick
        
        
          up loud and
        
        
          soft sounds.
        
        
          Can you tell what you are
        
        
          touching, without looking?
