gas pressure on Carmel Mountain
Question:

Lea lives with her parents in Haifa, Israel. Their home located in a beautiful Area that overlooks the sea from Carmel Mountain.

Last summer Lea went to La Paz, Bolivia, to a family visit. La Paz is a big city located at an elevation of roughly 3,650 m above sea level.During her first days in La Paz she has  suffered from headaches , dizziness and weakness. At the end of the week she felt much better.

How can  you explain  Lea's symptoms  first time in Bolivia, regarding her living in Carmel mountain all her life?

Before answering please play the folowing simulation: (notice how number of gas particles, temperature and volume effect gas pressure measured on a manometer).

During the increase in altitude , the temperature dencrease and so the oxygen pressure in the air layer that is above us increases. Mount Carmel is located at an altitude of 546 meters above sea level. There is no significant difference in the temperature on mount Carmel and the temperature on sea level, and thus the red blood cells can effectively bind the oxygen from the lungs and transfer it to all body cells successfully . However , at an altitude of 3650 meters there is a significant dencrease in the air temperature, leading to high oxygen pressure. This is too burdensome on the lungs , causing symptoms of headaches and dizziness.
During the increase in altitude , the mass of the oxygen particles in the air layer that is above us increases and so the oxygen pressure decrease. Mount Carmel is located at an altitude of 546 meters above sea level. There is no significant difference in the mass of the oxygen particles in the air layer above mount Carmel and above sea level, and thus the red blood cells can effectively bind the oxygen from the lungs and transfer it to all body cells successfully . However , at an altitude of 3650 meters there is a significant increase in the mass of oxygen particles in the air layer , leading to low oxygen pressure and no ability of red blood cells to effectively bind oxygen from the lungs.
During the increase in altitude , the volume of the air layer that is above us increases. So is the volume of oxygen. Mount Carmel is located at an altitude of 546 meters above sea level. There is no significant difference in the volume of the air layer above mount Carmel and above sea level, and thus the red blood cells can effectively bind the oxygen from the lungs and transfer it to all body cells successfully . However , at an altitude of 3650 meters there is a significant increase in the volume the air layer, and of Oxygen particles , leading to high oxygen pressure. This is too burdensome on the lungs , causing symptoms of headaches and dizziness .

I enjoyed reading your assignment. I like the fact that you wrote the question like a story. This makes it more interesting and makes the reader feel like a researcher that solving a problem. 

You used the map in the task, but I think that you need to put more information about the place.

You have spelling mistakes, for example- in the second line- you wrote lo and not to.

I couldn't open the video- you need to put it on youtube first and than copy the link here.

Wish you good luck.

Hi Haya!
I think the question is very good  and interesting to read. It is also connected to everiday life, which makes it even better.
I have a little problem with the distractors - all the answer options are very long and similar to each other. It rsembles more a reading comprehension task then a scientific one. Students who are good at understanding science, but have a problem concentrating (like ADD students), will find this question very difficult, despite understand the topic very well, becouse of the way the answers are written.
I think you should rephrase the different answer options, so they will be less similar to each other. also, there are some sentences that are present in each answer option. You could add those sentences to the question as additional information, and thus make the answers sorter and more clear. 

Regarding the information layers, I couldn`t open the animation but I saw it with you in class and I thing it helps to understand the topic. Also the point on the map is relevant to the question.

Suggestion
You could add a second point on the map - at La Paz, Bolivia.

Thank you for your comments!

For watching the animation, you need to install JAVA.

Thak you for your commend! I tried to wrote the question in interesting form and then i decided to write the question like a story.
i added information about the point in the map and i corrected spelling mistakes.

I agree with you that generally short answers are more comfortable for reading and understending. However , when
I tried to shorten the answers and expand the information in question, the result was not good in my eyes.  . Answers became less clear and less educateable.
Also, the level of thinking of the question decreased and was not challenging enough so I decided to leave the question as it is. Thank you very much for your importent comment.
