What changes are happening in our bodies?

Next we will measure heartbeat and breathing. Since breathing and heartbeat are measured at the same time, it is difficult for a student to do these two things well in the same time period. Therefore, in this activity, students are paired up, one person is the data collection object and is responsible for collecting breathing data, and the other is responsible for collecting heartbeat data.

Think about it:

When your body is in a calm state, measure your heartbeat and breathing rate per minute and record them.

Beat for one minute, then measure and record the number of heartbeats and breaths per minute

Please pay attention to solving the following problems while playing:

(1) Clarify the characteristics of a breath and a heartbeat

(2) After three minutes of exercise, measure the number of breathing and heartbeats
