Concept Overview:
- Four-chambered heart: Simulate left/right atrium and ventricle using tissue-covered cardboard domes.
- Syringes Create a pulsating heartbeat using a crank or cam mechanism connected to syringes.
- Tubes: Show direction of blood flow with red (oxygenated) and blue (deoxygenated) colored pipes.
How to Make the 3d Heart Working Model:
1. Build the Heart Structure (3D Look):
- Cut out 4 chamber shapes from cardboard: 2 small for atria, 2 larger for ventricles.
- Stick them on a cardboard base in proper position (like a real heart).
- Wrap each with red/pink tissue paper using glue to give a muscle-like appearance.
- Use red & blue paints to draw veins and arteries on the structure.
2. Create the Circulatory Flow:
- Connect syringes with tubing to simulate inlet and outlet of blood.
- Label tubes:
- Blue tubes for deoxygenated blood
- Red tubes for oxygenated blood
- Show arrows to indicate direction of flow.
3. Syringe Movement Mechanism:
- Attach syringe , it pulls and pushes syringe plungers to simulate heart contraction and relaxation.
4. Add Final Touches:
- Paint the heart with shiny red, pink, purple, add artery/vein details.
- Use tissue to create texture for myocardium (muscle).
- Add labels: Atria, Ventricles, Pulmonary artery, Aorta, Vena cava, etc.
