• Cigarettes can cause your blood pressure to become higher, also making
your heart work harder.
• A smoker’s blood may contain up to 15 percent less oxygen causing the
heart to work harder to get enough oxygen to the rest of your body.
Suggested Activities
• Allow students to hold the model. Ask them what observations they can
make about the model and have them discuss what they already know
about their heart.
• Copy and enlarge the model on page 2 as a quiz or review.
• Have students sit in a circle and start passing the two halves of the model in
opposite directions. When one student receives both halves at once, have that
student say one fact about the heart or name a part of the heart. After the
fact is determined to be correct, that student tosses each half to two different
students to start again. Remember the fact or part of the heart that was said
before should not be repeated more than once!
• Have each student take their pulse to get their resting heart rate. Tell them to
place two fingers to their neck under their jaw and count how many times
they feel their heart beat in 15 seconds and then multiply by 4. (Tell them
when to start and when to stop so they only have to focus on counting.)
Have them record their answer in a notebook. Then, instruct the students to
do jumping-jacks or a different physical activity for one-minute. After the
one-minute is up, instruct them to take their pulse again the same way as
before and record that answer. Discuss the differences in the two totals and
between students. Repeat the activity with a different physical activity to see
if there are any changes in the findings from the first activity and then discuss
the results.
