Subject: Science

Grade Level: Grade 4

Objective: Explain the function of the digestive system

Learning across curriculum:

1) Language Arts: Reading and comprehending informational texts about the

digestive system can enhance students' understanding of its function. By reading
texts about the digestive system, students can learn more about how it works and its
importance in the body.

2) Mathematics: Students can calculate the time it takes for food to travel through the
digestive system. By using mathematical formulas and measurements, students can
understand the process and timing of digestion.

3) Physical Education: Engaging in physical activities and exercises can help

students understand the effect of digestion on the body. By participating in physical
activities, students can experience the need for energy from the food they consume
and understand how the digestive system supports their physical activities.

Review Motivation:

1) Teaching Strategy: Interactive Quizzes

Instructional Materials: Quiz questions on the digestive system

Engagement Strategy: Interactive Quizzes

- Start the class with an interactive quiz about the digestive system to assess prior
knowledge and generate interest.

- Use technology tools such as Kahoot or Quizizz to make the quiz more engaging.

- Provide immediate feedback to students after each question to keep them

motivated.

2) Teaching Strategy: Storytelling

Instructional Materials: Storybook or picture book about the digestive system

Engagement Strategy: Storytelling

- Begin the lesson by reading a storybook or picture book about the digestive
system.

- Use expressive voice and gestures to capture students' attention and make the
story engaging.

- Encourage students to ask questions and participate in discussions about the story.

3) Teaching Strategy: Science Experiments

Instructional Materials: Food items (bread, banana, water, etc.), plastic bags,
plastic cups, digestive system diagram

Engagement Strategy: Science Experiments

- Conduct simple experiments to demonstrate the process of digestion.

- For example, place a piece of bread in a plastic bag with water to simulate chewing
and mixing with saliva. Then, transfer it to a plastic cup to represent the stomach.
Observe the changes in the bread over time.

- Discuss the observations and relate them to the function of the digestive system.

Activity 1: Digestive System Diagram

Teaching Strategy: Visual Aids

Materials:

- Digestive system diagram

- Colored pencils or markers

Significance:

- Students will label the parts of the digestive system on a diagram to reinforce their
understanding of its function.
Instructions:

1) Distribute the digestive system diagram to each student.

2) Instruct students to use colored pencils or markers to label the different parts of
the digestive system.

3) Assess students' diagrams using the rubric below.

Rubric:

- Correct labeling of all parts: 10 pts.

- Neatness and accuracy: 5 pts.

- Overall presentation: 5 pts.

Assessment Questions:

1) What is the function of the esophagus in the digestive system?

2) Name one organ where nutrients are absorbed into the bloodstream.

3) Explain the importance of the pancreas in digestion.

Activity 2: Digestive System Role-Playing

Teaching Strategy: Role-Playing

Materials:

- Character cards (mouth, esophagus, stomach, small intestine, large intestine)

- Props (food items, water)

Significance:

- Students will act out the process of digestion to deepen their understanding of the
function of each part of the digestive system.
Instructions:

1) Assign each student a character card representing a part of the digestive system.

2) Provide props such as food items and water.

3) Instruct students to act out the process of digestion, starting from the mouth and
ending at the large intestine.

4) Assess students' participation and understanding using the rubric below.

Rubric:

- Accurate portrayal of the function of the assigned part: 10 pts.

- Clarity and creativity in role-playing: 5 pts.

- Overall performance: 5 pts.

Assessment Questions:

1) What is the role of the small intestine in the digestive system?

2) How does the stomach break down food during digestion?

3) Explain the function of the large intestine in the digestive system.

Activity 3: Digestive System Concept Mapping

Teaching Strategy: Concept Mapping

Materials:

- Large chart paper or whiteboard

- Markers

Significance:

- Students will create a concept map to visualize the connections between different
parts of the digestive system and its function.
Instructions:

1) Divide the class into small groups.

2) Provide each group with a large chart paper or access to a whiteboard.

3) Instruct students to create a concept map by drawing and connecting the different
parts of the digestive system.

4) Encourage students to include labels and brief explanations of the function of

each part.

5) Assess students' concept maps using the rubric below.

Rubric:

- Accuracy and completeness of connections: 10 pts.

- Clarity and organization: 5 pts.

- Use of labels and explanations: 5 pts.

Assessment Questions:

1) How does the mouth contribute to the digestive process?

2) Explain the function of the liver in the digestive system.

3) Name one waste product of digestion.

ANALYSIS:

Activity 1 - Students demonstrated a good understanding of the parts of the digestive

system through their labeled diagrams. This activity helped reinforce their knowledge
and visual representation of the digestive system's function.

Activity 2 - Role-playing allowed students to actively engage in the process of

digestion, enhancing their understanding of each part's function. Students showed
creativity in portraying their assigned roles.

Activity 3 - Concept mapping helped students visualize the connections between

different parts of the digestive system. It facilitated a deeper understanding of how
the parts work together to achieve the objective.
ABSTRACTION:

The main point of the objective, "Explain the function of the digestive system," is to
understand how different parts of the digestive system work together to break down
food and absorb nutrients. By identifying the functions of each part and recognizing
patterns in their interactions, students can deepen their understanding of the
digestive process.

APPLICATION:

Task 1 - Research and Create a Digestive System Poster

Teaching Strategy: Project-Based Learning

- Students will research and create a poster about the digestive system, highlighting
each part's function and its importance in the process.

Task 2 - Design a Healthy Meal Plan

Teaching Strategy: Inquiry-Based Learning

- Students will design a healthy meal plan considering the digestive system's
function. They need to choose foods that provide essential nutrients and support the
digestive process.

ASSESSMENT:

Teaching Strategy: Discussion

Instructional Materials: Assessment questions

Question 1: Explain the step-by-step process of digestion in the correct sequence.

Question 2: How does the digestive system support the overall health of the body?

Question 3: Describe the role of enzymes in the digestive system.

Assignment:
Assignment 1: Food Diary

Teaching Strategy: Experiential Learning

- Students will keep a food diary for three days, recording the types of food they eat
and reflecting on how it affects their digestion and overall well-being.

Assignment 2: Create a Digestive System Model

Teaching Strategy: Project-Based Learning

- Students will create a three-dimensional model of the digestive system using

different materials, such as clay, paper, or recycled materials. They should label
each part and explain its function.
