We like to explore.

One of the study   with the cones of pine. Our students wanted to know :

Is there the air wet or dry in the classroom ?

They took plastic straw  and stuck  into the cones of pine.

The cones were opening and the straw began to move on right or on left.

All our straws moved into the side where 'dry'.

Therefore our students  noticed that our classroom is not wet.
