Pulse Rates

This week for science we were learning about our heart rates. A heart rate is the speed of the heartbeat measured by the number of processess of the heart per minute. 

First we learnt about high and low blood pressure by watching a video on what causes it. Something that causes high blood preasure is phsical activities. When you have a low blood pressure it's usally when you're relaxing.

We attempted different phsical activites to find out which activity causes a low blood pressure and a high blood pressure. The activites we attempted was sitting, jogging, throwing/catching a ball, streching, star jumps, and running. Sitting gave me a low blood pressure and running gave me a high blood pressure.

I enjoyed learning about high and low blood pressure.
