Internal Body Parts: A Glimpse

Active learning works for this topic because young children learn best by doing, feeling, and talking. When students listen to their own heartbeat, shape clay bones, or act out Simon Says commands, they build memory through movement and conversation rather than abstract facts alone.

Activity 01

• Placemat Activity
• 30 min · Pairs

Heartbeat Hunt: Pairs Pulse Check

Pairs sit quietly and place hands on each other's wrists to feel resting heartbeats, count for 15 seconds, then do jumping jacks for one minute and recount. Discuss why the number increases. Record findings on a class chart.

Explain why our heart beats faster when we run.

Facilitation Tip

During Heartbeat Hunt, have students sit quietly for 30 seconds before counting, so they notice the steady rhythm and feel the difference after jumping in place.

What to look for

Give each student a paper with a simple outline of a body. Ask them to draw and label where they think the heart and brain are. Then, ask them to write one sentence about what the heart does.

Activity 02

• Placemat Activity
• 45 min · Small Groups

Clay Organ Models: Small Group Builds

Provide clay in small groups to sculpt heart, brain, lungs, stomach, and bones inside a torso outline on paper. Label each and explain one function per organ. Groups present to class.

Predict what would happen if our brain stopped working.

Facilitation Tip

Before Clay Organ Models, demonstrate how to press and roll clay to show bones as slightly bendable, not rigid sticks.

What to look for

Ask students: 'Imagine you are playing your favourite game. What part of your body helps you run and jump? What part helps you think about the game?' Listen for their use of 'brain' and 'bones'.

Activity 03

• Placemat Activity
• 20 min · Whole Class

Simon Says Internal: Whole Class Action

Call instructions like 'Simon says touch where your brain is' or 'heart pumps faster, run in place'. Correct gently and explain organ roles after each round. Play three rounds.

Compare the function of our bones to the frame of a house.

Facilitation Tip

For Simon Says Internal, use only body commands that clearly involve the brain or bones, like 'Simon says touch your skull' or 'Simon says bend your knees'.

What to look for

Show pictures of different activities (running, eating, sleeping). For each picture, ask students to point to or say which internal organ is working hard. For example, 'When you run fast, which organ works faster?'

Body Map Draw: Individual Sketch

Students draw a simple body outline and colour or label five internal organs inside. Add arrows showing heart pumping or brain thinking. Share one drawing per student.

Explain why our heart beats faster when we run.

A few notes on teaching this unit

Teach this topic with short, clear explanations followed by immediate action. Avoid long lectures; instead, pair each idea with a quick game or craft so students feel the concept in their bodies. Research shows that movement combined with talk strengthens neural connections, especially in early grades. Keep your language direct and concrete, using what children already know—like ‘the heart is like a pump’—before moving to the next idea.

By the end of the activities, students will point to the correct places for the heart and brain on a diagram, describe one function of each organ in simple words, and show through gestures or words how internal parts help daily actions like running, thinking, or digesting.

Watch Out for These Misconceptions

• During Heartbeat Hunt, watch for students saying the heart makes blood.

  After students feel their pulse, ask them to trace the path of blood with their finger on their arm, then redirect: 'Listen, the heart beats to move blood that is already made. Who can show how blood travels from the heart to the hand?'

• During Clay Organ Models, watch for students treating bones as lifeless sticks.

  While students shape their bones, gently bend the clay to show slight flexibility, then ask: 'Can a stick bend without breaking? What does that tell us about bones?' Use this moment to link to milk and exercise.

• During Simon Says Internal, watch for students believing the brain only thinks happy thoughts.

  After the game, ask students to name actions they did like jumping or laughing, then point to their heads and say: 'Your brain told your legs to jump and your mouth to smile. It does many things, not just happy thoughts.'
