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!
