Student Outcome Expected At the end of this lesson, the students will be able to:
  1. Explain what happens to their hearts when different activities are done.
  2. Explain how to keep their hearts healthy.
  3. Use cooperative learning skills to work effectively in their groups.

Emphasis Level K-2 This lesson may be adapted to older grades by doing different activities and adjusting the language used.

Safety
  1. Check with school nurse about any physical conditions any student may have that would not allow him/her to participate in physical activities.
  2. Alert the students of the correct use of stethoscopes and the dangers of using them incorrectly.
  3. Keep paper towels/alcohol pads handy to clean the stethoscope after each use.
  4. Alert the students about running in place and the consequences to not following the rules.

Background information necessary for student understanding Students must have a basic understanding of what the heart does. They must also understand the components of a cooperative learning lesson..

Student Activity

  1. Present Mystery Organ chart.
  2. Briefly discuss the scientific method worksheet in a language consistent with the grade level.
  3. Break students into groups by using the color coded job tags.
  4. Experiment: There will be a recorder, listener and "doer" for each scenario. Begin by discussing stethoscope safety issues. Next, have the students either listen to their own or partners hearts, or feel the beat with their hands. One student from each group will be designated the runner for the first round. Tell the students that they must listen to the runners heart before the runner runs in place. Run in place for 20-30 seconds and stop when teachers say "TIME!" Listen to the heart beat again and have the recorder fill out the worksheet as to what he/she hears. Repeat the activity with a student standing and one lying down. The job tags will tell the student what the order is.
  5. Discuss the results.
  6. Discuss the affects exercise will have on the heart.
  7. Discuss the affects good nutrition will have on the heart.
  8. Discuss the affects smoking will have on the heart.
  9. Review the previous material by verbally asking the students questions.
  10. Hand out the Healthy Heart Certificates.
  11. Explain the certificates, question the students a final time about keeping healthy, have the students sign the certificates, and hand out materials from the Cancer Society.

Evaluation Techniques We will have worksheets for the students to fill out during the activity. We will also have a verbal question and answer time.

Materials Needed

  1. Heart model or diagram
  2. Poster of the heart
  3. Stethoscopes
  4. Job tags
  5. Stopwatch
  6. Student Certificate
  7. Student Worksheet
  8. Nutrition poster

POSTERS
  1. Mystery Organ Chart: *This poster has 5 questions that are covered with tagboard attached by velcro. It has probing questions that will require the students to think about the mystery organ. The top of the poster has a "door" with the human heart hiding behind it. After the students have made guesses on what the organ may be, reveal the heart.
  2. Nutrition Poster: *This poster has pictures of different foods to be placed into either a "Heart Healthy" or "UnHealthy" category. The pictures can be moved into the correct category.
  3. Heart Poster: *This poster is found in the American Heart Association School Site Kit. It is a picture of the circulatory system and gives the students an idea of what the heart looks like.
  4. Heart Model: *This model can be found in the curriculum library. It is a 3-D model of the heart.
