  1. New York State Learning Standards


MST Standard 4: Science The Living Environment

Living things are both similar to and different from each other and from nonliving things.

Key Idea 1:

1.1e Cells are organized for more effective functioning in multicellular organisms.

Levels of organization for structure and function of a multicellular organism include

cells, tissues, organs, and organ systems

1.1g Multicellular animals often have similar organs and specialized systems for carrying out major life activities.
MST Standard 2: Information Systems Students will access, generate, process, and transfer information using appropriate technologies.

ELA Standard 1: Students will read, write, listen, and speak for information and understanding.

ELA Standard 4: Students will read, write, listen, and speak for social interaction.

3. Materials


  • transparency showing unlabelled human digestive system (see attached)

  • overhead projector

  • permanent markers (for initials on cups)

  • 2 see-through glass or plastic cups, 240 ml (8 oz) in size (for each group)

  • dish detergent (for hand dish-washing)

  • small amount of vegetable oil

  • water

  • 2 stirring rods or spoons (for each group)

  • “Breaking Up is Easy to Do” worksheet (1 for each group)

  • On- line Digestive System Quiz (see attached)

  • Digestive System person (along with cut out parts and definitions) for Learning Center

  • Answer key for learning center

  • Digestive System Quiz (see attached)


4. Lesson Process

(A) Engage/Introduction (20 minutes)

Teacher will use the overhead projector to engage students’ prior knowledge by showing an illustration of the human digestive system. The teacher will have taught about the mouth, esophagus, and stomach prior to this lesson. The teacher will ask the students to identify these parts and to label the appropriate lines on the overhead. For assistance in spelling, the words will be listed on the easel pad at the front of the room.

The teacher can ask questions such as, “What does the mouth do to aid in digestion?”, “Where does the food go after we swallow it?”, “Can you tell me what happens to the food once it is in your stomach?”
(B) Explore/Learning procedures relating to objectives (1 hour 20 minutes - some of the time is simultaneous with the conclusion time)

The teacher will explain that the class will be conducting an experiment. This experiment is called Breaking Up is Easy to Do. It is to show how bile breaks down fat in the liver. However, the teacher will not reveal what digestive organ the experiment represents until after the experiment is complete. (While the students are waiting for the results of the experiment the teacher will go over the function of the liver along with some other digestive system parts.) The teacher will hand out the “Breaking Up is Easy to Do” worksheet

Students will be in groups of 2 or 3 (heterogeneous groups).

The teacher will go over the worksheet directions with the students. The teacher will remind the students of the importance of safe behavior during experiments (no throwing water, watch out for classmates as they move around the activity area, etc.). Students will fill out the worksheet up through step #8. (student to student) At that point the students are to leave their cups at the back activity table and return to their seats for the lesson.

After an hour the students will return to observe their experiments and fill out question #9-12. When the class returns to look at the water, oil, and dish detergent in the cups they will see that the dish detergent breaks the oil into smaller pieces. Groups will share their results with the class (student to teacher) “Breaking Up is Easy to Do” will be handed in upon completion.

Differentiation: As the groups are heterogeneous, students will work to the best of their ability to contribute to conducting the experiment. All learners can assist with getting supplies, marking cups with initials, getting water and oil, making predictions. Writing tasks can be shared as much as possible.



C. Explain/Conclusion (60 minutes – Some of the time will overlap with the Explore time)

While the class is waiting to finish the observation, we will continue to talk about the digestive system. Students will watch a 4 minute, animated movie at http://kidshealth.org/kid/htbw/_bfs_DSmoviesource.html about the digestive system. Students will take out the human digestive system diagram, which is the same as the overhead. The students started filling out this diagram in the prior lesson. The parts of the digestive system not yet discussed will be defined and labeled on the overhead as students add the information to their diagrams. New words will be added to the easel list of digestive parts. Each student will write the digestive definitions for each part in their science journal as the teacher writes the information on the overhead. Also, words, such as, bile and villi will be defined and added to their science journals.



New Vocabulary

liver small intestine rectum undigested

gall bladder large intestine anus toxins

bile villi solid waste

pancreas appendix tube
Differentiation: For students who need assistance with note taking, the teacher can make copies.
(D) Extend, Expand, or Elaborate

Go to: http://hes.ucfsd.org/gclaypo/digestivequiz.html#multiple%20choice. (See attached)

This is a digestive system multiple choice and true/false, 10 question quiz. Answers can be corrected until they get the right answer. There will be no scores recorded. Students are to sign their name on the sheet next to the computer when they complete the quiz.
Differentiation: This quiz is good for all level learners as the students can answer until they come up with the correct answers. For those who need assistance with reading, another student, aid, or teacher can work with the students.
(E) Evaluation/Assessment

a) Learning outcomes of previous lessons related to this topic:

Students will be able to explain the definition of molecules, cells, peristalsis, enzymes, and acids.

SWBT explain nutrients and the purpose of the digestive system.

SWBT identify the location of the mouth, esophagus, and stomach within the human anatomy.

SWBT explain the function within the digestive system of the mouth, esophagus, and stomach.

b) Focus of assessment in this lesson

Students will be able to identify the liver, gall bladder, small intestine, large intestine, pancreas, appendix, rectum, and anus as components of the digestive system and the functions of each along with related vocabulary.

SWBT locate the liver, gall bladder, small intestine, large intestine, pancreas, appendix, rectum, and anus on a diagram of the human anatomy.

. c) Methods of assessments used in this lesson

informal – participation in experiment and class discussions

on-line quiz on Digestive System (done/not done)

formal – “Breaking Up is Easy to do” worksheet (attached)

Digestive System Quiz (attached)





  1. Differentiation of expected outcomes

i) Students with learning disabilities – “Breaking Up is Easy to Do” worksheet will be done with partners. Students will be expected to contribute to the best of their ability. Students with difficulty writing can have their partners write down answers as they dictate. All group members will receive the same grade. All students can help with experimental part of assignment unless physically handicapped. Digestive system quiz can be read to students, if necessary.
ii) Gifted or talented students can add more detail to the “Breaking Up is Easy to Do worksheet for the required explanations.


  1. Lesson modifications

i) Students with learning disabilities – Copies of the digestive system components diagram can be given to students with all parts labeled. Notes of digestive system terms and functions can be copied for students who need assistance. On the digestive system quiz multiple choice questions can be paired down to 2 or 3 choices. Students can give answers orally, if necessary, for other responses.

ii) Gifted or talented students – students be more detailed in explanations on the “Breaking Up is Easy to Do” worksheet. If these students have extra time additional terms, such as epiglottis, pharynx, duodenum, can be researched.

6. Student work (attached)
7. Learning center

The learning center is a summary of the digestive terms and functions (8) learned in this section of the unit. The students will arrange and label the main digestive system parts discussed in class.

Answer key can be checked after learning center is completed.

Differentiation: For students having difficulty learning the information, the answer key can be used as an aid. Also students can be assisted in reading the definitions.
