Complete each section with details needed so you have carefully logged your project...and so an outsider can know and understand too.

1	My science investigation TOPIC:  Pulse Rates
2	My investigation question Investigate the effect of different types of physical activity on the heart rate/pulse rate. Which actions/activity resulted in the highest heart rate? Which actions/activity resulted in the lowest heart rate? Why do you think this might be? Hypothesis:  1, I think running as fast as possible on the spot will give me the highest heart rate. 2, I think stretching will have the lowest heart rate.
3	Background research and knowledge I will explore as a backdrop to my investigation High Blood Pressure - 120 and above mmHg Low Blood Pressure - 80 and below mmHg
4	Aim of my investigation To find the highest and lowest heart rate while doing activity
5	My investigation steps Materials: Stop watch, smart watch, tennis ball (for catch) People: My partner Angelica STEP 1 Put on the watch tightly STEP 2 Wait for your watch to go down to your heart rate STEP 3 Do the activity while using a stopwatch (30 sec) and read the heart rate STEP 4 Write it into the Collection table STEP 5 Repeat
6	My possible recording method Data collection table:  Name of the Activity Length of Activity Beat counted in 30 seconds Heart Rate mmHg Sitting 30 seconds 97 97 mmHg Jogging on Spot 30 seconds 160/88 160/88 mmHg Throwing and Catching ball 30 seconds 118/91 118/91 mmHg Stretching 30 seconds 95/90 95/90 mmHg Star Jumps 30 seconds 138/100 138/100 mmHg Running as fast as possible on spot 30 seconds 150/120 150/120 mmHg     Photos:
7	Result:  Which actions/activity resulted in the highest heart rate? Jogging on Spot - Hypothesis - Running Which actions/activity resulted in the lowest heart rate? Stretching - Hypothesis - Stretching  Why do you think this might be? High heart rate: While tuning your heart needs more oxygen Low heart rate: Stretching makes your heart rate faster, but goes down afterwards because it is relaxing for the nervous system.
