Answer 1

Answer: Raymond Wang: How germs travel on planes – and how we can stop them

1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?

In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.

2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.

It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.

3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?

He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.

Answer 2

Answer:

1. The air circulates in the cabins so when a person sneezes the air will get swirled around multiple times and spread the disease.

2. Many diseases like sars, don't show up on simple testings and the person could have a disease early on and it would be nearly impossible to identify.

3. He illustrates how the air is being circulated throughout the plane. When someone sneezes, the contaminated air is being circulated throughout the plane. This means that everyone on that plane has breathed in that person’s sneeze because it’s so compact.

4. Wang’s invention can stop the spread of disease because it pushes all of the air down meaning if someone coughed or sneezed, instead of spreading around the cabin, the air would get pushed down to the filtration system before reaching multiple people. The word “flow” has to do with his solution because he is redirecting the flow of the air in the airplane downwards to prevent more people from getting sick.
