ACTIVITY #5 | My Journey In Science 4

-

 


WHAT TO DO: 

1. Create a graphic organizer that will show how air (oxygen) travels through the different organs of the respiratory system.



2. Make a sketch of the different organs of respiration and state the function of each part in your own words. 


Organs of Respiration and its Functions

Nasal Cavity and Paranasal Sinuses -  to filters, warm and humidify the air we breath. These give you a feeling of smell.

Nostrils - these uses to smell things, breathe, and (sometimes) sneeze. To warm air on inward breath and remove dampness on exhalation.

Larynx - is responsible for production of sound. It moves when we swallow. When we speak, air is forced into this small gap by the lungs. This prompts vocal cords to vibrate which produces sound.

Trachea - allows air to pass from the pharynx to the lungs.

Bronchi - shuttle air to and from the lungs.

Lungs - reliable for adding oxygen and removing carbon dioxide from the blood.

Oral Cavity - serves the secondary passage for air to enter and exit the respiratory tract during inhalation and exhalation.

Pharynx - conveys air from your mouth and nose to the trachea.

Alveoli - allow gas exchange

Diaphragm - this creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.



3. Create a Poster on the Effect of Smoking in Cardiovascular and Respiratory System.


This poster shows how smoking affects our lungs and heart.

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...
