  1. Sit down with a family member and measure the pulse rate in their radial artery. You can do this by placing your index and middle finger on the underside of their wrist, below the base of the thumb. Take three separate readings (30 seconds each). Calculate the beats per minute by multiplying each reading by two and find the average. Record this in table one. This value will also be your trial 1 result in table two.
  2. Have your relative repeat step one on you.
  3. You and your family member will run on the spot for three minutes. Use a timer to guide you. Immediately after the three minutes, check each other’s pulse by following the instructions at step one. Record these results in trial 2.
  4. Rest for five minutes and measure each other’s pulse rate again. Record this as trial 3.
  5. Repeat steps three and four two more times. This will give you the results for trials 4-7.

Table one:

Pulse rate 1

Pulse Rate 2

Pulse Rate 3

Average

Table two:

  1. Compare your pulse rate to that of your family member. Give a possible reason (s) for any difference observed.

  1. The normal pulse rate for adults is 60-90 beats per minute. Compare this to your pulse rate. Give a possible reason (s) for any difference observed.

  1. How does your pulse rate change after running on the spot? Why do you think this happens?

Answer #1

Table one our pulse rate

1 st pulse rate 68 b/min

2nd pulse 70 b/ min

3rd pulse 68 b/ min

Average 68 BTS / min

You have to do the rest of the experiment at your home

Answer to the final question asked

Yes there is difference between my pulse and my family members pulse rate because as the aging process take place our heart rate will increase to cope up with the increasing blood supply need of our body he to Exersice. The basal metabolic rate increases with Exersice so heart rate increases

When reporting your vital signs be sure to measure heart rate in beats per minute, respiration rate in breaths per minute and blood pressure as systolic/ diastolic in mmHg (these measurements should look like 120/70). You can do this lab on yourself or on someone else. #1.

Task #1: Respiration Rate Changes in Minnows as a Function of External Temperature (adapted from exercise developed by Daphne McKay) Introduction Counting gill cover movements is a way to calculate respiration rates in fish. Fish breathe by taking water in through the mouth and forcing it over the gills when the mouth closes. An oxygen-carbon dioxide exchange occurs. Then the operculum opens to allow the carbon dioxide-rich water to exit. The respiration rate changes in response to changes in the...

Shamus’s family come to talk to you about their his care. They want to speak to you because they trust you as someone who has worked very closely with Shamus as a palliative care worker for the last two months. They are very distressed about a report they have received from the doctor, who has told them that Shamus has only days to live. His family ask you to refer them to a different doctor – there must be something...

This week you will collect time measurements and organize your observed data into a frequency distribution table and a relative frequency histogram. Start by choosing something you can time easily in seconds. (Thing about events that typically take between 20 seconds and 3 minutes.) You will need to collect at least 30 observations. Be as consistent as you can with your time measurements. Most of you have smart phones with easy-to-use apps with timers already built in. If your measurements...

Experiment 1: Gravimetric Analysis with Calcium Chloride and Potassium Carbonate In this experiment, proper analytical experimental techniques will be utilized to perform a double displacement reaction. A solution will be prepared containing a known quantity of calcium chloride. Then, the mass of calcium present will be determined through a careful precipitation of calcium carbonate. You will also investigate the hygroscopic nature of calcium chloride through a comparison reaction. Materials: Scale250 mL Beaker50 mL BeakerStir rod4.0 g Calcium chloride, CaCl25.0 g...
