1. EdMedia Fall 2009 Dominican College Fall Trimester 2009 Joseph Facey Prof. Andrew Chalfin

2. LESSON PLAN HUMAN DIGESTION AND PRIMARY STRUCTURES

3. Learning Standards Students 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. Goals Students 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 lesson students should be able to name the primary structures of digestion

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

16. Anticipatory Set Last 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 contd Teacher 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

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

25. Motivation From 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 cont Following 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 contd Teacher 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.

31. ORGANS NEED PRITECTION

33. Student will sketch the digestive system and label it as best they can or label one provided.

36. Student will sketch the digestive system and label it as best they can or label one provided.

38. Questions contd 4 What do you see as a possible outcome if food is not chewed properly? 5 What would happen if a person’s salivary gland does not function well? 6What do you think about the process of digestion?

39. Interactive Diagram Students will be able to touch the different organs and get information
