Activity 01
Role Play: Food's Journey Through Body
Assign roles: one student as food particle, others as mouth, oesophagus, stomach, intestines. Food moves station to station while parts describe actions like chewing or mixing. Groups perform and explain to class.
Explain what happens to the food we eat after it leaves our mouth.
Facilitation TipDuring the Role Play, give each student a small sign showing their assigned body part and ask them to move in sequence as you narrate the journey.
What to look forGive each student a drawing of the digestive system with blank labels. Ask them to label the mouth, oesophagus, stomach, and small intestine. Then, ask them to write one sentence about what happens to food in the stomach.

Activity 02
Model Building: Simple Digestion Tube
Use a long tube, balloons for stomach, food scraps, and water. Pour food in, squeeze through tube sections to show path. Observe changes and discuss nutrient absorption.
Predict what would happen if one part of our digestive system stopped working.
Facilitation TipWhile building the Model Digestion Tube, remind students to use clear plastic pipes so they can see the food’s path and add labels from their vocabulary chart.
What to look forPose this scenario: 'Imagine your stomach stopped churning food. What do you think would happen to the food? How would your body get energy?' Facilitate a class discussion, encouraging students to use the vocabulary learned.

Activity 03
Chewing Experiment: Bread Breakdown
Give dry bread pieces; students chew one bite well, swallow pretend, compare to unchewed. Note easier mixing with saliva. Record feelings and share why thorough chewing helps.
Justify the importance of chewing food thoroughly before swallowing.
Facilitation TipFor the Chewing Experiment, provide plain bread slices and ask students to chew one slice ten times and another slice five times, then compare the lumps.
What to look forAsk students to show with their hands the path food takes after leaving their mouth. They can use gestures to show swallowing, moving down a tube, and churning. Observe for correct sequencing and understanding of movement.

Activity 04
Group Chart: Digestion Path
In groups, draw body outline, label organs with food journey arrows. Add what each does, using colours for energy parts. Present to class with predictions if one stops.
Explain what happens to the food we eat after it leaves our mouth.
Facilitation TipWhen creating the Group Chart, provide a large poster paper with a simple outline of a human body and ask groups to place cut-out labels for each organ in the correct spot.
What to look forGive each student a drawing of the digestive system with blank labels. Ask them to label the mouth, oesophagus, stomach, and small intestine. Then, ask them to write one sentence about what happens to food in the stomach.

Generate Complete Lesson→A few notes on teaching this unit
Teachers should avoid telling the whole story at once. Instead, let students discover the process through guided actions and models. Research shows that children aged 6 to 8 learn body processes better when they use their own bodies or hands-on materials rather than reading or listening alone. Always connect the science to daily life, such as asking students to think about how they feel after eating too much or too little.
By the end of these activities, students should be able to name and locate the mouth, oesophagus, stomach, small intestine, and large intestine. They should explain that food breaks down gradually through chewing, churning, and absorption, and finally leaves the body as waste. Their language should include terms like saliva, juices, nutrients, and waste.
Watch Out for These Misconceptions
During the Role Play activity, watch for students who say food disappears in the stomach.
Use the role play to stop at the stomach and have students mime churning while you narrate, 'Food does not vanish. It breaks into small parts here.' Then ask them to continue the role play to the intestines and finally to the toilet to show waste exit.
During the Chewing Experiment activity, watch for students who think chewing is not important.
After students chew bread slices five and ten times, ask them to describe which lump is easier to swallow and why. Guide them to notice that saliva mixes with food to make small, soft lumps for safe swallowing and quick breakdown.
During the Model Building activity, watch for students who only label the mouth and stomach.
Provide a checklist of all organs and require students to place and label each part in sequence before testing their model. Ask them to trace the path with a finger as they explain what happens in each organ to reinforce the full journey.
