Cystic Fibrosis

1.) Cystic Fibrosis is a disease that causes mucus to build up in the lungs, airways, and digestive system.

2.) Officially, Cystic Fibrosis was not discovered until the 1930's when the earliest paper on the disease was written by Dr.Fanconi, a Swiss pediatrician. However, there has been suspicion of it sense the early 1700's including an old German saying, "A child whose forehead tastes like salt when kissed will soon die."

3.) Symptoms include delayed growth, salty tasting skin, cubed fingers, no bowel movements in the first 24-48 hours of life, failure to gain weight during childhood, belly pain, fatigue, coughing, and shortness of breath.

4.) It is caused by a defective gene and id recessive.

5.) There are tests to detect the cf gene including a blood test and a test that measures salt levels in sweat.

6.) There are many treatment options depending on the severity of the case. Inhaled medicines, antibiotics, and in severe cases, lung transplants are options.

7.) Cystic Fibrosis cannot be prevented.

8.)Currently the Scripps Research Institute is leading research on Cystic Fibrosis.

1. What are 3 scientific facts that you learned from watching Journey to the Center of the Earth?
I learned about Muscovite, that magnesium is flammable, and to bring a bag with you to the center of the Earth in case you find diamonds.

2. What are 3 things in the movie that were scientifically untrue.
There is no secret world in the center of the Earth, dinosaurs are extinct, and if you were sitting in a dinosaur skull and you fell from that height you would probably die.

1. What was your favorite topic that we learned about this year in Earth Science?

My favorite topic that we studied this year was the geologic time scale. I thought it was going to be astronomy but it turned out to be the geologic time scale.

2. Explain this topic. Provide a picture and/or website link to better illustrate what you learned.

The geologic time scale is a timeline that shows Earth's entire history. It is divided into eons, periods and epochs.

3. Why is this so cool? Mr. Dunn likes a lot of stuff that we do (that's why we do it). Why did you like this particular topic?

I think it is so cool because it easaly organises all of the time periods and tells what kind of creatures lived during this time.

1. What are the four ways astronomers can detect extrasolar planets?
The four ways to find a planet are radial velocity, astrometry, transit method, and optical detection.

2. Choose one of the four ways and explain it in detail.
Transit method is when a planet passes in front of its star. this causes some of the light form the star which reduces its apparent magnitude. This can tell you how long the planet takes to move in front of the star.

3. In your answer to #2 you chose one way that astronomers detect extrasolar planets. Search the Internet to find how many extrasolar planets have been detected using this method.
45 extrasolar planets have been detected using the transit method.

The Big Bang Theory attempts to explain the formation of the universe. What do you think the universe looked like before the Big Bang? What made the universe "bang?"

I think that brfore the Big Bang happened there were other nebulas and planets that we know nothing about because there was a black hole in the center of everything and the blach hole exploded and maybe distroied all of the planets that were already existing, but created the galexies that we see today.

Which planet of moon is your favorite and why? Please include a picture.

My favorite planet is Jupiter. Jupiter is my favorite planet because of its size. The Red Spot is only a small storm compared to the entire planet, yet it can fit three Earths inside. No one can ever imagine seeing something so big unless we have actually seen it before. So the size of this giant gas planet is what makes it my favorite.

In your opinion, is Pluto a planet? why or why not? Please include a picture.

Pluto is not a planet. It is a dwarf planet. There are several reasons why I think so.

The first reason is that Pluto has not cleared its orbit. This means that Pluto and its moon, Charon, revolve around each other as they revolve around the sun.

Another reason is that Pluto is not much bigger than its moon. It is barely twice as big as Charon. Other planets are at least a few times bigger than their moons. Pluto is not big enough for Charon to revolve around it. This is why Pluto is not a planet.
