Hi bloggers!!

We did a project in class.

The project consists in see the process of the respiratory system in

the lungs.

The materials that we have were this:

-Two balloons

- A bottle

- Scissors

Steps:

      1. Cut the bottle in half

      2.  Cut a balloon in half

      3.  Put the balloon in the half of the bottle

      4.  Introduce the other balloon in the other part of the bottle.

 Conclusion: When we pull the rubber, the balloon blow up.

                      When we push the rubber, the balloon deflate.
