Big Brain Questions

We have started to examine the parts of the nervous system. During class discussion some interesting question have been raised. Such as 
"How does the brain store memory?" 
" How does a human brain compare to a computer?" 
"About how many laptops would it take to equal the information processing of a human brain?" 


What are your big questions about the nervous system and how it works?

Intelligence

What is intelligence? Is memory part of intelligence? When you think of a person as intelligent or smart what traits does that person have?

Respiratory System 5

When we studied the circulatory system we learned about some of the people who contributed to the scientific knowledge about the circulatory system. Scientist and doctors such as Jarvik , Harvey, and Galen all helped us to better understand the heart and how it works. Who has helped us understand more about the respiratory system? 

Respiratory System 5

Try to connect any of the following as it pertains to  the respiratory system. 

Nicotine + 


or

 +

How are these two objects related ?

Respiratory System 4

Nicotine is a chemical in tobacco products. What is the affect of nicotine on the body? What are some of the other chemicals used in tobacco products and what affect do they have on human body systems? 

Respiratory System 3

There are several diseases and disorders of the respiratory system. What are some of the origins of these diseases and disorders, how did they  start? Are there any new or recently discovered respiratory system diseases and disorders? 

Respiratory System 2.13.12

Why is it an advantage to have lungs with many smaller air sacs instead of having just two large sacs like balloons? 

Teaching and Learning Science

The recent trend in science education is a philosophy described as having learning that is deeper than broad. Thinking of science education as a body of water, either having it an inch deep and a mile wide, or an inch wide and a mile deep. What are your thoughts on this trend do you think it would be more beneficial to learn a little about  many topics or to explore a single science topic deeply? 

Respiratory System 1

Looking at the formula on page 93 of the text book, how does that compare to the process of photosynthesis?

Testing out of a topic 2.8.2012

Do you think it would be a good idea to have a test before we go over a topic? Next we will tackle the respiratory system if a person were to pass a test what should that person do during science class ? What about being given just list of topics and assessments for learning and everyone learn at their own rate ?
I look forward to everyones ideas on this topic.

Blood and Lymph 1

Why is cancer of the blood cells or lymph nodes hard to control?

lymph 1

How does the lymphatic system work with the cardiovascular system?

What are some diseases of the blood? What are causes symptoms and treatments for  disease of the blood . 

Blood 2

What is hemophilia? Why would a relatively minor cuts and bruises be hazardous to a person with hemophilia? 

Blood 1

Please research and report about the role of vitamin K , prothombin, calcium ions , thrombin, fibrinogen, and fibrin in the mechanism of blood clotting. 

circulatory system 8

Pulse rates can rise and fall from exercise. What are some factors that can effect the pulse rate.  When is an increase in pulse rate beneficial? When is it harmful? 

circulatory system 7

Identify the following as having oxygen rich or carbon dioxide filled blood.
aorta


coronary arteries 


coronary veins 




inferior vena cava 


left atrium 


right atrium 


left ventricle 






right ventricle 


superior vena cava 

What is the color of blood?

The past few weeks the question of the color of blood has come up on class.  Is blood always red ? Is blood sometimes blue? Can blood change color? Thinking further what does cause something to have color? Is there color  if light is absent? 
Please remember to cite your sources so others may see where you gathered your information. 

Circulatory System 5

There are two types of circulatory systems open and closed. Please give an example of an organism that has an closed system and one that has an open system.  Compare and contrast and open system to a closed system.

Circulatory System 4

The last few post of the challenge blog have traced the development of human understanding of the circulatory system. Ideas about how a system works can start with misconceptions about the true nature of a system. One such misconception was that veins carried air through out the body. Please research and post some common misconceptions that were held about the circulatory system. Did you have any  personal misconceptions about how the circulatory system works?  Please share your misconceptions or how your understanding about the circulatory system has changed.

Circulatory System 3

What contributions did Christiaan Barnard and Dr. Jarvick  make to medicine? What further advances have been made in areas which Barnard and Jarvik worked.

Circulatory System 2

William Harvey and Dr. Daniel Hale both were important in the development of our knowledge of the circulatory system. Tracing  how knowledge of the circulatory system developed where does the work of Galen fit.  What other individuals have contributed to the scientific knowledge of the circulatory system.

Circulatory System 1

Who was William Harvey and what did Harvey do to develop his theory of circulation? Does the work of will Harvey still hold relevance in medical research today? What connection can you make between the work of William Harvey and Dr. Daniel Hale Williams?
