The Cardiac Cycle, Heart sounds, and Blood Pressure | My Journey In Science 4

-


Today is September 28,2020. Before our class started, our teacher asked us if our internet connection is good and He said we will not finish the two hour class and we will only use one hour because we will have our online recognition that will take place after his class.

We started our class with an opening prayer lead by Juliane, and then proceeded to our lesson. On the first slide of the power point, our teacher asked us to tell our answers about our activity last time. My teacher called me first to answer his question, I answered with confidence but I later found out that my classmates and my teacher could not hear me. So I needed to exit the meeting to restart my phone but it was fixed immediately and I was able to answer again.

What I learned about our lessons for today is about the Cardiac Cycle, Heart Sounds, and Blood Pressure.  Wherein the cardiac cycle pertains to the sequence of events that happen when the heart beats. The  cardiac cycle consists of the heart's alternate and rhythmic systole and diastole of the atria and ventricles. As the heart relaxes and contracts, a distinctive heart sound is produced.



I was able to know about heart sounds and how they are produced. The difference between "lub" and "dub".  I clearly understand also about blood pressure and its measurement. Blood pressure is the force exerted by the circulating blood upon the walls of the blood vessels. 



A sphygmomanometer measures blood pressure. The stretching of the artery caused by the pressure of the blood is called pulse. I get familiarize also about the systolic and diastolic pressure. I have learned also the eight pulse sites i a human body such as the temporal artery, facial artery, carotid artery, brachial artery, radial artery, femoral artery, popliteal artery and dorsalis pedis artery.



And that's it for today! Our teacher ended up his lesson with an activity. I hope you learn more about our class today.

Electron Configuration and Noble Gases | My Journey In Science 4

Today, we just recapped about the lesson we tackled last meeting which is about the Atomic Bond, Octet Rule, and the Valence Electrons. Our teacher assigned us to identify the electron configuration of the other elements using the noble gases and the Pauli's Exclusion Principle.                       Above is one of the example our teacher assigned us to do. We first used the Noble Gas notation then after that we used the Electron Configuration which is the longest one to write.  We use noble gases to add shortcut on the Electron Configuration. W e will just follow the next aufbau principle with the last aufbau principle with the noble gas provided. For the Electron Configuration, we are just going to follow the aufbau principle until it reaches the exact amount of the atomic number of the element we need.

THE PHYSICISTS| My Journey In Science 4

  Research for the following personality: 1.1 Ernest Rutherford Ernest Rutherford is the father of nuclear chemistry and nuclear physics. He discovered and named the atomic nucleus, the proton, the alpha particle, and the beta particle. He discovered the concept of nuclear half-lives and achieved the first deliberate transformation of one element into another, fulfilling one of the ancient passions of the alchemists. 1.2 Niels Bohr Niels Bohr completely transformed our view of the atom and of the world. Realizing that classical physics fails catastrophically when things are atom-sized or smaller, he remodeled the atom so electrons occupied ‘allowed’ orbits around the nucleus while all other orbits were forbidden. In doing so he founded quantum mechanics. Later, as a leading architect of the Copenhagen interpretation of quantum mechanics, he helped to reshape our understanding of how nature operates at the atomic scale. 1.3 Max Planck Max Planck changed physics and our understanding...
