Science Investigation(STEM 2021)

 Science Investigation

Task 1:

What causes Blood pressure?

1. If you run a lot you get  Blood pressure

2. MMHG

3. 60-80 MMHG

4. 120-80 MMHG= High Blood pressure.

Task 2.

Carefully read and understand this recording and planning guide so you are systematic in scientific thinking, experimenting, recording and interpreting. 

Follow logically through each section so you are thorough in your science investigation steps. 

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:
2	My investigation question Which physical Heart Rate Result in High and low  Blood pressure.
3	Background research and knowledge I will explore as a backdrop to my investigation   What is Pulse rate/ Heart Beat? Pulse rate is your measure of your Blood pressure.
4	Aim of my investigation. To find out your questions.
5	My investigation steps Materials / resources / people: Ocean,Aleki and Texas Tennis ball, stop watch, smart watch. STEP 1 We get a Watch and stop watch. STEP 2 We Did different Physical Activity STEP 3 Got one Person to do the stop watch . STEP 4 We record our Heat rate.   STEP X Wrote it all down on a document.
6	My possible recording method Data collection table:  Name of the Activity Length of Activity Beat counted in 30 second Heart Rate mmHg Sitting 30 seconds 55mmHg Jogging on Spot 30 seconds 111mmHg Throwing and Catching ball 30 seconds 82mmHg Stretching 30 seconds 84mmHg Star Jumps 30 seconds 109mmHg Running as fast as possible on spot 30 seconds 80mmHg     Photos and Videos:
7	Result:  1.The Lowest Heart Rate Was:Sitting down 2:The Highest Heart Rate was:Jogging on the spot. 3:What you think this might be: it saws our heart beat.
