  1. 1. Go To Lesson Activity Home Page http://www.powertolearn.com/teachers/lesson_activities/index.shtmlTitle: Tales From the TummyGrade Ranges:___K-4_X_5-8___9-12Subject Tag:Science: The Human BodySynopsis:Students will employ creative writing to describe the journey of a hamburger through thehuman digestive system in order to reinforce the structures and functions of the humandigestive system.Keywords:digestion, student writing, creative, reinforcement, digestive process, organs, organsystem, structure, functionBody:Prior to assigning this activity, have students read about the human digestive systemand/or discuss the subject in class. Students should be familiar with each digestive organand its role in the digestive process. A diagram of the digestive system would helpstudents visually trace the flow of food through each organ. If textbook resources arelimited but Internet resources are available, have students visit http://www.brainpop.comand pick the movie on the digestive system for a good (and funny) overview. Ask students to pretend they are hamburgers. Then, ask them to be creative andwrite about a journey from mouth to anus. Students must name each stop or passagewayin the digestive system and describe what happens to them at each place. The story canbe general or specific, based on the level of instruction or preparation beforehand. Forexample, a very detailed story would describe which parts of the hamburger (bun, cheese,lettuce, meat) were digested at what point in the system. A very general story might justinclude which parts of the system are involved in ingestion, digestion, absorption, andelimination.Related Links:Brain Pop: http://www.brainpop.com (great general health, science, and technologyresource for middle school kids)Features:___Contains special education tips_X_Quick Activity (less than 30 minutes; story starter)___Requires Internet access for students to completeObjectives: 1
  2. 2. 1. Students will be able to describe each organ of the human digestive system and itsfunction.2. Students will be able to distinguish between mechanical and chemical digestion.Standards:NY: Living Environment 4.1. Living things are both similar to and different from eachother. Living Environment 4.5. Organisms maintain a dynamic equilibrium thatmaintains lifeNYC: Life Sciences Concepts S2a. The student produces evidence that demonstratesunderstanding of: Structure and function in living systems, such as the complementarynature of structure and function in cells, organs, tissues, organ systems, whole organisms,and ecosystems.CT: 5. Relationships Of Structure And Function: describe ways in which internal andexternal structures, organ systems and body plans contribute to organisms being able tocarry out life functions or processes (e.g., reproduction, response to stimuli, productionand/or digestion of food, and production of energy, circulation, excretion, homeostasis);NJ: 5.6. All Students Will Gain An Understanding Of The Structure, Characteristics,And Basic Needs Of Organisms — Recognize that complex multicellular organisms areinteracting systems of cells, tissues, and organs.Time Required:30 minutesAssessment Criteria: A rubric or checklist may be helpful to make sure the studentdiscusses each organ and its function. (The following chart is also reproduced in theaccompanying teacher download.) # Organ Included Function Notes 1 Mouth (teeth, tongue, jaws) 2 Salivary Glands* 3 Esophagus 4 Stomach 5 Small Intestine 6 Liver* 7 Gall Bladder* 8 Pancreas* 9 Large Intestine10 Rectum/Anus Totals 20 possible points *Could be optional as food does not pass through these organs.Recommended Lesson Plan Review Date: 2
  3. 3. 6 monthsReview Comments:Because the Brain Pop web site is included as a focus resource, the link should bechecked every 6 months. 3
