Students are read a book on senses.


The senses are part of the nervous system.  Touch, smell, sound, sight, and taste are all controlled by the brain.  If the information cannot get to the brain through the nervous system, there is something wrong with the network of nerves.

Senses are very important to science.  They help a person investigate.  Chemicals are sometimes invisible and we need to use our smell to detect them.  Sight helps us many times, but children don’t realize that the other senses are also very important.  An object can look “cold” but when you touch it, the object is really “hot.”


  1. There are many books on senses.  You probably have a favorite one or your library may have one that explains senses in a clear and enjoyable manner.  Go over the vocabulary words.  Have the students repeat the words several times.  Make sure they know what part of the body is responsible for the senses.  The recommended book clearly summarizes all of the senses. 
  2. There are some senses that are organs or  specific body part.  For example, ears hear sound, eyes can see, a nose smells, and a tongue can taste.  Touch, however, is a very large organ called the skin.  Explain to your students that there are sensitive parts of the skin.  Your fingertips, for example, are more sensitive than skin on your leg.  Ask your students how they sense things. 
    The brain however, is the main organ that regulates and allows our body to interpret all these senses.  If the brain is damaged, it can affect parts  of the body that are far from the brain.  
  3. As you discuss each part of the body, have your students observe each part.  Let the students look into each other's eyes.  Ask them to describe what they see. They will come up with a list of "discoveries" because although we all have eyes, we rarely try to describe them.  Ask the same questions for the other parts of the senses including skin, tongue, nose, and ears.  Emphasize that these senses help us discover and describe the world around us.
