• 2. Science Standard 2- Scientific Thinking
• Indicator 4.2.4
• Use numerical data to describe and compare objects and events.
• Taken from
• http://www.indianastandardsresources.org/files/sci/sci_4_2_4.pdf
• 3. Definitions
• Compare - To examine in order to note the similarities or differences of.
• Describe - To give an account of in speech or writing.
• Heart Rate - The number of heartbeats per unit of time, usually expressed as beats per minute.
• Numerical Data - is data measured or identified on a numerical scale.
• Observe - To be or become aware of, especially through careful and directed attention; notice.
• 4. Background Information
• Using numerical data to describe and compare objects and events may seem difficult or something that is hard to do, but, in fact, it is very simple. For this activity, we will count the number of times our heart beats in one minute. Then, we will record that number and compare our number with a partner’s number to see how they differ. We will count our heart beat on two separate occasions to see how they differ. Once will be at rest, and the other time will be after we did 30 jumping jacks.
• 5. What is Your Heart Rate??
• 6. Purpose/Materials Needed
• Purpose
• Students will use their numerical data to describe and compare their heart rate before and after exercise. Then, they will compare and contrast their numbers with a partner.
• Materials Needed
• Stopwatch
• Pencil
• Notebook
• 7. Pre-activity Questions
• -What is a Heart Rate?
• -How many times a minute do you think your
• heart is beating right now?
• -How many times a minute do you think your
• heart would beat after you did 30 jumping
• jacks?
• 8. How to Check Your Heart Rate.
• To check your heart rate you must place your fore finger and your middle finger on one side of your neck and find your pulse. After you do this, you will need to have your partner time you for 30 seconds while you count the number of times that your heart beats. Then, you will multiply that number by 2 and that will tell you how many times you hear beats per minute.
• 9. Activity
• Step 1
• Split students into pairs
• Step 2
• Explain to students how to check their heart rate (directions on previous slide)
• Step 3
• Have students take turns timing each other while they find their heart rates and have them write their numbers down in their journals.
• Step 4
• Then, have one partner in each group do 30 jumping jacks and have that person find their heart rate for a minute again. Have them record that number as well.
• Step 5
• Have the other partner repeat step 4.
• Step 6
• Have students compare and contrast their numbers.
• 10. Post- Activity (Answers to be wrote down and turned in)
• How many times did your heart beat in a minute at rest?
• How many times did your heart beat in a minute after 30 jumping jacks?
• When did your heart beat the fastest?
• Why do you think your heart beat changed?
• How did you use numerical data in this activity?
