This lesson plan outlines a lesson on the human digestive system for 4th grade students with disabilities. The goals are for students to understand the functions of the digestive system and be able to name its primary structures. The lesson includes examining posters and models of the digestive system, discussing each part, and using computers to interact with diagrams. Students will label diagrams of the digestive system and write about the journey of food through it. Their understanding will be evaluated through worksheets and questions.

2. LESSON PLANHUMAN DIGESTION AND PRIMARY STRUCTURES

3. Learning StandardsStudents will understand and apply scientific concepts, principles and theories pertaining to the physical setting and living environment and recognize the historical development in science. Students will access, generate, process, and transfer information using appropriate technologies

4. Analytical description of students:This is a class of fifteen adolescent students with disabilities within demographics described, as a moderate needs school.Grade Level – 4th Grade

5. GoalsStudents will demonstrate their understanding of the functions of the digestive system through their ability to discuss and describe (in their own words) the functions and the steps starting from the mouth.

6. Objectives: At the end of the lessonstudents should be able to name the primary structures of digestion

7. Material: Posters illustrating different parts of the digestive system

8. Lesson Plan

9. Model of different sections of the digestive system

10. Computer with internet access

11. Workbooks

12. Crayons

13. Drawing paper

14. Projector

15. SmartboardTeacher’s ExpectationTeacher will acknowledge the technology prowess of the students and be sure to let students know that everyone of them can learn. Teacher will stress the importance of technology in the classroom and students will be told that the lesson will be concluded using the computer to work with interactive models. The more advanced students will be required to assist their slower classmates.

16. Anticipatory SetLast time we looked at the different systems of the body and we did go into details of the skeletal system. We dealt with the functions and the different sections. Today we will be learning about the digestion system. How is the digestive system different from the other systems we have studied? Are you ready for a study of some of the different parts of the digestive system?

17. Simple Diagram of Human Digestive System

18. Procedure:Teacher and students will examine the posters and all the material illustrating the process of digestion.Teacher will draw student’s attention to the unfamiliar phrases and words, e.g. Esophagus etc

19. Procedure contdTeacher will engage students in a discussion through which, teacher will be sure to bring out and note on chalkboard, pertinent facts about the system in question

20. Stomach & Large Intestine

21. Procedure contdStudents will learn the following facts about the digestive system:-The digestive system includes the gastrointestinal tract— (mouth, pharynx, esophagus, stomach, small and large intestine)

22. Along with these are accessory structures – (teeth, tongue, salivary glands, liver, bladder and pancreas)Procedure contdFood materials are broken down to usable nutrients and absorbed into the bloodstream.

23. Teacher will reiterate that the process of digestion starts in the mouth.

24. Teacher will ask students to say what goes on in the mouth when we eat.Interaction ContdStudent will point to name of an organ which in turn lights up on model

25. MotivationFrom observation teacher knows the excitement that exist when it comes to the use of the computer and other gadgets in the classroom and so teacher will borrow laptops from other teachers in order to accommodate every student of the class.

26. Procedure contFollowing students’ responses, teacher will verify that in the mouth chewing initiates the mechanical breakdown of food and is followed by secretion of saliva, which moistens and lubricates food for swallowing. Teacher will help students to understand the purpose of digestion (to break food down to molecules that can be used by cells)

27. Procedure contdTeacher lets students know that there are three principal processes involved in this process of digestion -: (a) mechanical digestion, (b) chemical digestion and (c) absorption.

28. Closure:Students will use the computer lab to research mechanical digestion, chemical digestion and absorption

29. THE STOMACH

30. Evaluation:Students will be given simple charts with the digestive system to label the parts indicated.
