1. A Collaborative Learning Community Don t Get too Stressed by Ethan Burgharat PHEOCS Investigation There are many things that can happen when you are scared First your muscle cells lose polarity When you are at rest your muscle cells are polarized When they are facing emotions there are an excess amount of ions across the muscle cell membranes These ions are positive sodium ions An excess amount of these causes a positive charge on the cell membrane An EKG or ECG sensor can read the potential positive charge of the cell membrane in millivolts mV Information was found on the EKG sensor manual provided by Vernier P H EOCS Background Information Questions What is your pulse rate My resting heart rate is 87 beats per minute Your heart rate depends on what 3 things e Blood pressure maintenance temperature and heart health Where can you measure your pulse rate on your body e Your wrists and neck How do you measure your pulse rate at your wrist e You can count the beats you feel in 30 seconds and double it How do you measure your pulse rate at your neck e You find a vain and count the amount of beats in 30 seconds times 2 Describe step by step how you take your pulse rate e First you find the artery right below your chin and half way to the back of your neck e Next you press your index and pointer finger in the hollow feeling spot e Last you count how many beats while watching a clock for 30 secon2.
