Your Heart: The Super Pump Hero!

Hello, little heroes!

Did you know you’ve got a superpower inside you? It’s your heart—a mighty pump that squeezes blood all around your body like a superhero water gun! Thump, thump—it never stops, not even when you’re sleeping.

Your heart is a muscle that works hard every day. It squeezes to push blood through tubes called blood vessels, sending oxygen and food to every part of you—your toes, your brain, even your nose! Then it pulls the blood back to get more power. It’s like a water gun that squirts life all over, keeping you strong and ready for action.

Feel your chest—can you sense your heart pumping? It’s your own superhero at work!

Try This Heart Pump Experiment!

Want to see how a pump moves stuff? Let’s make one!

What You Need:

• A plastic bottle (empty, like a water bottle)
• A balloon (blow it up a little—ask a grown-up to help)
• A straw
• Water
• Tape or a rubber band
• A bowl or sink (to catch splashes)

What to Do:

1. Cut the top off the bottle (a grown-up should do this part).
2. Stretch the balloon over the cut end and tape or tie it tight—it’s your “heart!”
3. Poke a small hole in the balloon and push the straw through—tape it so no water leaks.
4. Pour a little water into the bottle through the straw.
5. Squeeze the balloon gently. Does water squirt out the straw?

What You’ll See:

When you squeeze the balloon, water shoots out the straw—just like your heart pumping blood! Let go, and it relaxes, ready for the next pump.

Why It Works:

Your heart squeezes to push blood out, then relaxes to fill up again. The balloon pump moves water the same way, showing how your heart keeps going, thump after thump!

You’re a heart hero now! Feel your heartbeat after running—can you count the thumps?
