The heart is like a powerful pump that keeps our body supplied with the blood it needs to function. It’s a vital organ, roughly the size of a clenched fist, located in the center of our chest, slightly tilted towards the left.

Imagine the heart as a transportation system for blood, which carries essential nutrients and oxygen to every cell, tissue, and organ in our body. It also picks up waste products, like carbon dioxide, and transports them to the lungs for removal.

The heart is divided into four chambers: two atria (the upper chambers) and two ventricles (the lower chambers). These chambers work together in a rhythmic dance, squeezing and relaxing in a coordinated manner to ensure blood flows smoothly.

The heart has a complex network of blood vessels, including arteries that carry oxygen-rich blood away from the heart, and veins that bring oxygen-depleted blood back. This continuous cycle is what keeps us alive.

As our heart beats, it makes the familiar “lub-dub” sound, which is the sound of the heart valves closing to prevent backflow of blood. It beats around 60 to 100 times per minute, depending on factors like activity level and age.

In summary, the heart is our body’s dedicated pump, tirelessly working to ensure our cells get the oxygen and nutrients they need, while also helping remove waste. It’s truly a remarkable organ that keeps us alive and well!

In this project, we’ll make a dynamic working model of a heart using cardboard, colored paper, a balloon, and a syringe to simulate the heart’s pumping action. Here are the steps:

Materials Needed:

  1. Cardboard sheets
  2. Color paper (red, blue, and white)
  3. Balloon (latex or rubber)
  4. Syringe (without needle)
  5. Glue or adhesive
  6. Scissors
  7. Marker
  8. String (optional, for added stability)
  9. Craft knife (adult supervision may be required)

Building the Heart Model:

1. Creating the Heart Chambers:

Step 1: Draw and cut out two heart shapes from cardboard. These will serve as the upper and lower chambers of the heart (atria and ventricles).

Step 2: Cut out two smaller heart shapes to represent the heart valves. Attach them at appropriate places within the chambers using glue.

2. Adding Blood Vessels:

Step 3: Cut strips of red and blue color paper to represent blood vessels. Attach them to the chambers to simulate the veins and arteries.

3. Making the Balloon Pump:

Step 4: Cut a small section off the neck of the balloon and stretch it over the opening of the syringe. Secure it tightly with a rubber band or string.

Step 5: Attach the syringe to one of the chambers (ventricle) using glue. Ensure it’s securely fixed in place.

4. Completing the Heart:

Step 6: Attach the upper chamber (atrium) above the ventricle with the syringe, leaving space for the balloon to expand.

Step 7: Add additional details using color paper or markers to represent veins, arteries, and heart muscles.

5. Demonstrating the Pumping Action:

Step 8: Gently press the syringe plunger to inflate the balloon. This simulates the heart’s pumping action.

Step 9: Release the plunger to allow the balloon to deflate, representing the relaxation phase.

6. Optional Base (if needed):

Step 10: If you wish to display the model on a base, cut a piece of cardboard to fit the heart and glue it in place.

Your dynamic working heart model is now complete!

When you operate the syringe, it simulates the pumping action of the heart, pushing blood through the chambers and valves. This interactive model provides a visual representation of how the heart works.
