How do we breathe?

In Science, the students of 2nd grade have been studying the human body. Among other things, they have discovered, by experimenting, the way in which we breathe.

First, students drew the two lungs on a card, and they colored them. Then, with the help of the teacher, they punched a hole in each of the lungs, and they inserted the balloons. After that, they blew into the balloons to see how the lungs expanded and contracted with air as they breathed.

Overall, it was a really motivating and enriching experience. Students really enjoyed the project, and they were really happy about taking their lungs home, so that they could tell their families about the experiment.
