Learning Standard 3.3.2: Sequence the Flow of Food During Digestion

🎯 Learning Development & Desired Learning

Learning Objectives

•Arrange digestive organs in correct sequence
•Trace the pathway of food from mouth to anus
•Identify what happens at each stage of digestion
•Understand the time taken for each digestive phase

Desired Learning Outcomes

✓Students can correctly order all digestive organs
✓Students understand sequential nature of digestion
✓Students can predict next step in digestive process
✓Students connect sequence to digestive efficiency

✅ Success Criteria

Beginning Level

• Identifies mouth as first step
• Names stomach and intestines
• Places 3-4 organs in correct order
• Recognizes food moves through body

Developing Level

• Sequences all major organs correctly
• Includes esophagus in pathway
• Distinguishes small vs large intestine
• Explains why sequence matters

Proficient Level

• Creates complete digestive pathway
• Includes accessory organs (liver, pancreas)
• Explains timing of each stage
• Predicts effects of sequence disruption

Interactive Food Journey Sequence

Click on each step to follow the food's journey through your digestive system:

1

Mouth (Oral Cavity)

Mechanical breakdown and initial enzyme action

30 seconds - 2 minutes

⬇️

2

Esophagus

Transport tube using peristalsis

5-10 seconds

⬇️

3

Stomach

Acid digestion and protein breakdown

2-4 hours

⬇️

4

Small Intestine

Major nutrient absorption site

3-5 hours

⬇️

5

Large Intestine (Colon)

Water absorption and waste formation

12-48 hours

⬇️

6

Rectum & Anus

Waste storage and elimination
