Option 1 Have you ever watched online tutorials about how to create an art project, how to do a trick, or how to use a new strategy in a game?

Think about a tutorial that you could create for other students. Your purpose will be to help someone your age complete the steps in the tutorial. Write, edit, and revise a short script. Be sure to include specific details. You also may want to include some props, diagrams, or images to communicate your instructions.

Option 2

In an informational text, the author’s primary purpose is to inform readers. The author uses clear language that can be organized in a variety of structures, such as chronological or compare and contrast, to effectively present the information.

Think about an event that will be happening in your school or community that you’d like to inform others about. How would you present this information to students and others in your community? What is your topic? What organizational structures, word choice, print and graphics, or other elements could you use? Write a description of how you would present the information

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. the respiratory system does this through breathing. when we breathe, we inhale oxygen and exhale carbon dioxide. this exchange of gases is the respiratory system's means of getting oxygen to the blood. respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. oxygen enters the respiratory system through the mouth and the nose. the oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. in the chest cavity, the trachea splits into two smaller tubes called the bronchi. each bronchus then divides again forming the bronchial tubes. the bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. the average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. the inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. the carbon dioxide follows the same path out of the lungs when you exhale. the diaphragm's job is to pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. the diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. as the diaphragm contracts and relaxes, breathing takes place. when the diaphragm contracts, oxygen is pulled into the lungs. when the diaphragm relaxes, carbon dioxide is pumped out of the lungs. write one paragraph (at least 6 sentences) describing the path of oxygen through the respiratory system. also include why this "order of operations" is the way it is!
