The
first 30 minute teaching period will be used to complete procedures 1 -
7. The second 30 minute teaching period will be used to complete
procedures
8 - 15.
There
may be a need to call attention for safety while a group of students are
doing movements inside the classroom.
Remind
students to let the teacher know if they are not feeling well before they
begin or at any time during the lesson.
When
calculating the rate of heartbeats per minute, students will count the
number of heartbeats in fifteen seconds and multiply that number by four.
This answer equals the number of heartbeats for one minute.
Make
certain that each student has a school/county Acceptable Use Policy on
file.
Students
should have prior knowledge of basic computer skills.
The
teacher should secure the use of the computer lab.
1. As an introduction to the lesson, ask the students what happens to their bodies when they run or move rapidly. Record the responses on the board. Lead the students to "Their hearts beat faster after exercising."
2. Put this statement (Their hearts beat faster after exercising), on the board.
3. Ask the students if they can think of a way to measure their heartbeat rate.
4. Put KWL chart transparency on the overhead projector.
5. Hand out the KWL worksheet. Ask students to think about and write the meaning of heartbeat, heart rate, and pulse, and describe the location of their pulse on the "K" (What I Know) section of the worksheet. Ask them to fill out the "W" (What I Want to Know) section of the worksheet.
6. Put Scientific Explanation transparency on the overhead. Read and discuss the terms and information.
7. Demonstrate the correct procedure for locating and checking a pulse (Must use Internet Explorer or Netscape 7.0 to access this link).
8. Ask students if they have ever had their pulse checked by a medical professional. Let them describe the procedure. Extrapolate the need for counting beats in a certain amount of time.
9. Demonstrate for the students the procedure for checking a pulse (Must use Internet Explorer or Netscape 7.0 to access this link) for one minute using a digital stop watch as the timing device.
10. Allow students time to check their own pulse three times and record this information on a sheet of paper.
11. Ask the students if the beats per minute changed and what might cause this change.
12. Discuss the way to shorten the procedure by counting the beats for fifteen seconds and multiplying that number by four.
13. Ask for a volunteer to demonstrate this problem on the board. Help students calculate their own pulse rates per fifteen second times four.
14. Ask the students what they could do to increase their heart rate. Let students discuss different activities they could do in the classroom to increase their heart rate. Teacher should lead the students to suggest such activities as running and jumping.
15. Using a computer projection device, the teacher will guide the students to the web site Why Exercise Is Cool to view information on exercise and a healthy body. The students and teacher will discuss what effects exercise has on your heart.
16. Students will then go to the web site Having Your Heart in Your Mouth to read the expression, "having your heart in your mouth", as a figurative language statement. The teacher and students will discuss the meaning of figurative language and what makes this statement an example of figurative language.
17. Using a projection device, the teacher will guide the students to the web site "Resting Heart Rate" and the class will view the information on resting heart rate. Students will discuss the differences in the results at the web site and their own.
18. Hand out "How Does Your Heart Rate" worksheet. Instruct students to write on this worksheet the number of beats for fifteen seconds and the number of beats per minute for sitting.
19. Call attention to the need for safety while a group of students are doing movements inside the classroom. Remind students to let the teacher know if they are not feeling well before they begin or at any time during the lesson.
20. Have the students stand beside their desks and walk in place for one minute. The students are to immediately check their pulses for fifteen seconds and calculate the rate for one minute and record the information on the worksheet.
21. Have the students to sit quietly while you check their charts. This will give the students time to rest. Discuss the need to bring their heart rate down to a resting rate before they complete the next activity.
22. Repeat steps 20 and 21 for completing the jumping jacks and running in place activities.
23. Ask students to complete the "L" (What I Learned) section of the KWL worksheet. Ask students to discuss some of their answers.
24. Record some of the responses on the KWL transparency and discuss. Discussion should lead to the conclusion that one's heart rate increases with the level of physical exercise.
25. Using a projection device, the teacher will guide the students to the web site "Resting Heart Rate" and the students will view information on resting heart rate. Students will discuss the differences in these results and their the results they recorded of their own.
Consult with special education department regarding specific IEP and 504 requirements.
Students
may check and calculate the pulse of other students at rest and/or after
a physical activity in the classroom.
Students
may check and calculate the pulse of their parents at rest and/or after
a physical activity for homework.
The evaluation will be based on the Exercise and Heart Rate Rubric.
