This week, the 2nd ESO students of the optional science subject did an
exercise about the respiratory system.
This exercise consists of checking our heartbeat and breathing before
walking, after walking, and after running during 2 minutes for each exercise.
With this activity, we checked our heartbeat and breathing and we
discovered that after doing exercise, our heartbeat and breathing were higher
than before.
During this class, we enjoyed and rediscovered the changes that occur
when you run!!
