                           1.  Use various objects to stimulate different sense organs and discuss the process.

                                How do you feel these objects?
                           2.  Pat your head with your right hand and make a circular motion on your stomach

                                with the left hand. Find out why the combined motion is difficult.

                          Lab Activity


                           Ask the students to form a single line by joining hands. Explain that each student |

                           represents a nerve cell and the whole line represents a nerve. Tell the students to pass
                           along a hand squeeze when a signal is given to begin the activity. When the squeeze |

                           reaches the last student, he or she should shout ‘‘Got it!’’

                           Explain that messages travelling through a body pass from one nerve cell to another

                           in a similar manner.
