Heart rate experiment.

We made an experiment that finally proved that the faster we move and the more physical exercise we make, the faster our heart beats.
In order to do that, we first predicted what it was going to happen to our heart rate after doing some physicaql activity although at the beginning, we had some problems finding our pulse. Then we took note of the beats per minute (BPM) after looking at the ceiling, after jumping for a while, after going down and up the stairs once, and after going down and up the stairs twice. We leart about pulse rate , we revised measuring and multiplications and we had great fun!
Then we made an esthetoscope in our art clas
