The Heart Rate Investigation

The emphasis of this lesson is for students to see that their heart rate will increase after 1 minute of jumping jacks because the cells need additional oxygen while exercising, making their heartbeat faster. Students will first take their pulse at rest and record it. Students will then do 1 minute of jumping jacks and record their pulse immediately after the 1 minute of jumping. Students will then take their pulse again after resting for 1 minute to see how their pulse starts to decrease. Students will continue recording their pulse to see how many minutes it takes to return to resting.
