Experiment with the respiratory system!

Hello! 

4th grade students have worked very hard last weekend at home...

They built a model of the respiratory system with some materials.

They used a plastic bottle, a plastic bag, two balloons, two straws and plasticine...

Have a look to the amazing results...
















Do you identify the lungs?



Here you are our English assistant showing  how it works. 


Do you dare to make it at home? Have a try! 

Bye-bye little scientists!
