The purpose of this activity is to have students use their senses in various
situations. The situations are such that students find out that their senses
are not always accurate.
(For each group of four)
Orange juice, nondiet cola, apples, candy (such as mint or lemon drops), plastic
dishpans or washbasins, (large battery jar instead of plastic dishpans or
washbasins), large beaker.
On the day before beginning the activity make sure the materials needed are
available. If you do not have foodstuffs such as sugar, table salt, flour,
baking soda, corn starch, etc., in the laboratory, you may wish to have students
bring them from home.
1) The instructor will lecture to the class giving them examples of the various
types of senses, smell, taste, hearing, seeing and touch.
2) Encourage student participation.
3) Allow student to practice at various stations attempting to prove their
theory of which sense is most important.
The expected outcome of the five activities are such that the students
understand that there is not a dominant nor non-dominant sense. In order to
identify various sensations correctly you need all five senses.
