Teaching Objective
The student will gather, organize, and display data on a double bar graph. (Attachment #1)
2 Instructional Activities
Introduction
Engage students in a discussion about double bar graphs.
o The teacher will define double bar graph. (Attachment #2)
o The teacher will describe the use for a double bar graph. (Attachment # 2)
o The teacher will show an example of a double bar graph. (Attachment #3)
Invite a health professional to class to share basic information about the heart.
o The teacher will be sure to inform the health professional ahead of time about the topic. The focus of the presentation is on the heart rate when the body is at rest and the heart rate following exercise. (A health professional could be a science, health, or PE teacher, coach, fitness trainer, nurse, etc.)
o The teacher will explain to the students the purpose of the health professional.
Demonstration
Describe and model the day’s activity.
Gather the data.
o The teacher and Health Professional will serve as a group. They will take their heart rate and record it on the Data Recording Form.
o The teacher and Health Professional will each choose a different activity from the Activity List.
o The teacher and the Health Professional will perform the activity they chose for the length of a song.
o The teacher and Health Professional will take their heart again and record it on the Data Recording Form.
Organize the data.
o The teacher and the Health Professional will discuss the range or interval needed to display the heart rate for each of their activities on the double bar graph. (Decisions will be recorded on the Data Recording Form.)
Display the data.
o The teacher will set up a double bar graph.
o The teacher will use the Data Recording Form to graph their heart rates before and after performing the activities.
Student Practice
Divide the class into groups of three.
Gather the information.
o The student will take their heart rate and record it on the Data Recording Form in Part One. (Attachment #4)
o The student will each choose a different activity from the Activity List. (Attachment #5)
o The student will perform the activity they chose for the length of a song. The entire group will perform their activity at the same time.
o The student will take their heart again and record it on the Data Recording Form.
Organize the information.
o The students will discuss the range or interval needed to display the heart rate for each of their activities on the double bar graph. Decisions will be recorded on the Data Recording Form in Part Two.
o The students will discuss an order for placing the activities on the Data Recording Form. Decisions will be recorded on the Data Recording Form.
Display the information.
o The student will set up a double bar graph using the directions in Part Three of the Data Recording Form. (Attachment # 4)
Assessment
Introduction & Demonstration Lead a discussion.
o The teacher will monitor student response to the objective given and vocabulary used.
Student Practice
Observe the class.
o The teacher will walk around and assist students as needed.
o The Health Professional will assist students with checking their heart rate.
Ask the class questions.
o The teacher will observe students at work and ask them to explain the step they are working on and then their next step.
Assessment
Review the lesson.
o The teacher will ask students questions about gathering, organizing, and displaying data on a double bar graph.
o The teacher will answer questions from the students.
Complete a journal entry.
o The student will answer questions in their journal. (Attachment #6)

Part One
Gather the Data
Directions: Use the chart below.Step 1: For #1-3, write the student name and the activity they choose in the first column. (There should be three different students with three different activities.)
Step 2: Take your heart rate. Record it in the column “Heart Rate Before.”
Step 3: Perform the activity you chose for the length of a song. The entire group will perform their activity at the same time,
Step 4: Take your heart rate again and record it on the chart below in the column labeled “Heart Rate After.”
