YEAR 4: HOW WE BREATHE

Hello bloggers,

Have you ever wondered how we breathe?
The diaphragm changes the amount of space inside our chest when we breathe in and out.

Year 4 students made a project using reclycled materials such as plastic bottles and straws. They had to simulate how our lungs work.

Here you have some pictures showing the final result:

Now I want you to think:

- What do the straws, the balloons and the plastic bags represent?

See you later bloggers!
