A BEATING HEART

Lesson Plan

Cube Fellow: Jason Collett

Teacher Mentor: Tara Barnett

Goal: To use cardiac physiology to increase understanding of percents and percent difference.

Grade and Course: 9th Grade, Algebra 1

KY Standards:

MA-HS-1.3.1

MA-HS-1.4.1

Objectives:

1. Students will perform a hand on experiment working as a group

2. Students will be able to collect and analyze data

3. Students will be able to calculate % difference

4. Students will be able to relate algebra concepts with basic cardiac physiology

Resources/materials needed: Worksheets, stopwatch, and a calculator

Description of Plan:

Students will have a lecture pertaining to percent and percent difference a day before this lesson

is presented. On the day of the lesson, a short and simple introduction into the efficiency and

productivity of the human heart will be given. Students will then be instructed how to estimate heart

rate by measuring an individuals pulse. Students will break into groups of two or three and provided

with a stopwatch, calculator and worksheet. First, the students will be given the fact that the average

human heart rate is 72 beats/min. The students will be asked to calculate how many times, based

upon this average, the heart will beat in 24 hours, 16 years and 100 years. Then, one group member

will be chosen as the “experimental subject”, as their heart rate will be measured. The chosen

member of the group will sit in a chair, as another takes his or her pulse, while the other monitors the

clock. A resting heart rate will be measured twice, and an average will be taken. The experimental

subject will then be asked to do 30 jumping jacks, then sit in the chair and have his or her heart rate

measured again, as before. The members will then be asked how the heart rate has changed, and to

calculate percent difference. Time permitting; each group member can obtain a resting and post-

exercise heart rate. The students will then be faced will real life examples in which heart rate may

change from rest. Students will be asked to calculate percent increase and decrease, as well as be

given percent differences and asked to calculate heart rates.
