The Digestive and Excretory Systems
or Where Does Your Food Go?
Materials: none needed
Objectives: 1. Students know which parts of their bodies are part of the
digestive system and which are part of the endocrine system.
2. Students can tell in sequence where food goes once they
begin to eat.
3. Students point to the part of the body that corresponds to
the place where the food goes.
Activities: Students each select or are given a part of the body that he/she
will be. (For example: Joe is the esophagus.) The teacher calls on
someone to be the food. That person, as the teacher names the different
places, where the food goes, each person raises his/her hand as his part of
the body is called. The person being the food goes to that person just as
the food would. Parts/places where the food goes are called in order:
mouth with teeth & saliva, esophagus, stomach, arteries (move food to all
parts of the body), veins carry food from all body parts (to the excretory
system), small & large intestines & kidneys, out as trash (when person
uses the bathroom).
As students can remember the sequence, vary the activity.
Students tell which part comes next. Each part says when iti s his turn to
have the food. Have students from the excretory system and from the
digestive system get into groups according to which system their body part
belongs to. Have 1 student tell the entire sequence while each part sits
down or stands up.
Evaluation: observation, informal check-off or oral quiz
