A good place to measure your pulse is the artery on

the thumb-side of the wrist. Touch this area lightly

with the index finger of your opposite hand until you

feel your heartbeat. Count the amount of heartbeats

for 15 seconds and multiply by four - this will give

you your pulse rate.

Measure the pulse of other people in your

household. Try to answer some of these

questions: Does pulse vary with age? Does

it vary with time of day (morning, afternoon,

bedtime)? What happens to your pulse after you walk up stairs?

Do girls have lower, higher, or the same pulse rates than boys?
