Easy Science Experiments, Heart and lung experiment

What’s the heart and lung experiment? It’s easy science experiments to do at home, after we make this kit, the students or kids will learn more about the Heart and Lung.

Games of heart and lung experiment

Let’s play a game first. How long can children hold their breath, and how will their bodies change when they hold their breath?

Start, the children’s faces are red, feel the importance of breathing to our body!

We also put our hands on our chest together to deeply feel the changes in our chest when we breathe!

The question is, what do children know about the respiratory organs in their bodies? Where is it? Let’s go into today’s small experiment with the questions!

The whole body needs oxygen. To burn the energy stored in the body, let them become heat energy, organs and muscles get heat energy to move.People get oxygen through their lungs. so it is important to measure the volume and the number of activities in the lungs.

The heart is responsible for delivering oxygen to various organs and parts through the blood circulation system. So the strength of the heartbeat will affect the blood flow.

How do the Lung works?

lung model with balloons explanation.

Cardiopulmonary diaphragm refers to the heart, lungs, and diaphragm.

When the balloon is pulled down, the volume of the balloon becomes larger and air enters the balloon. That is to say, when the diaphragm moves downward, the volume of the lung becomes larger and gas enters.

When the balloon is released, the volume of the balloon becomes smaller and the air is discharged from the balloon. That is to say, when the diaphragm moves upward, the volume of the lung becomes smaller and there is gas in and out.

This experimental kit uses materials to make a lung model. When students or kids don’t understand the significance of the simulation experiment, they simply use materials to make a lung model, then they lose the significance of design.
