This investigation allows students to measure their heart rates after different physical activities. It will allow them to see that the more vigorous the activity, they higher their heart rate will climb. It also allows areas for reflection and can be used for further learning throughout the year. This is a great activity to begin a fitness unit or to even start at the beginning of the year.
A great cross curricular approach as well, incorporating math and the need for addition and multiplication when measuring beats per 15 seconds to beats per minute.
