1. What are the four ways scientists can detect planets?
Radio Velocity, Astrometry, Transit Method, and Optical Detection are the four ways scientists detect planets.
2. Which way makes the most sense to you? Explain it.
Transit Method because there is an instrument that shows when there is a dip in the brightness of planet which is most likely being blocked by another planet.
-----------------------
3. Explain the concept of the "Goldilocks Zone."
The Goldilocks Zone is an area of space in which a planet is just the right distance from its home star so that its surface is neither too hot or too cold. That means that the planet could possibly have liquid water.
4. If Gilese 581c does have life, what do you think it would look like? How would it act? Would it be intelligent?
If they had life then it would most likely look like giant fishes since the planet is covered in mostly oceans. I think they would swim everywhere and may be violent. I think they would be smart enough to hunt for their own food and make living environments for their babies.
5. Do you believe in aliens? Why or why not? Give me a solid paragraph.
Yes because there is no proof of any alien life yet, but scientist believe they are a lot closer to discovering them because of all the recent discoveries they have found in the Goldilock Zone. There have been many failed attempts to find these aliens, but maybe one day we will be in contact with them or have proof of their existence.

Blog Post 1 !
1.Search for aliens (SETI)
The SETI institute was founded in 1984 as a nonprofit corporation and in 1985 NASA awarded the institute a contract to play a major role in a search being performed by the space agency. They use radio telescopes to search for alien signals being sent to Earth.
2.Milky Way Galaxy
The Milky Way is the galaxy which is the home of our Solar System with at least 200 billion other stars. The Milky Way is actually a giant, its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years All the objects in the Milky Way Galaxy orbit their common center of mass, called the Galactic Center .
3.Red Giants
When the core of the star is hotter than it was during its normal life and the heat causes the outer parts of the star to swell. The star becomes a giant. The radiation from the fusing shell grows weak by the time it reaches the surface of the star. Weak radiation is red, so the star becomes a red giant.The Sun will run out of fuel and become a red giant in about 4 billion years.
4.Black holes
Black holes have a strong suction force, they may only suck up what crosses their event horizons, and they are not capable of absorbing the whole universe. The known closest black hole to Earth is Cygnus X-1, located about 8000 light years away. Although whiteholes are mathematically possible, there have yet to be observations to prove their existence. As black holes age they gain more mass as they suck in more matter
5.Mars
Mars is named after the Greek God of War. Mars is referred to as the Red Planet because of its distinct red color. ItMars had a magnetic field like the Earth, but has lost it. tTemperatures are generally cold, ranging from -200 to a maximum high of 80 degrees Fahrenheit. Mars has roughly the same surface area of the Earth, but is much less dense. A Martian day is a little over 24 hours.

Blog Post 1 [Ughh ! ]
1. Which hurricane did you choose?
Hazel
2. What category was it on the Saffir-Simpson scale?
Category 4
3. Tell its story.
The hurricane slowly turned around and turned again and crossed the southeastern of Bahamas.This Hurricane caused 95 deaths and $281 million in damages in the US. High winds occurred over large portions of the eastern United States. Myrtle Beach, South Carolina reported a peak wind gust of 106 mph, and winds were estimated at 130 to 150 mph along the coast between Myrtle Beach and Cape Fear, North Carolina. Washington, DC reported 78 mph sustained winds, and peak gusts of over 90 mph occurred as far northward as inland New York state. A storm surge of up to 18 ft inundated portions of the North Carolina coast.
4. How many lives were lost? How much damage did it cause ($)?
95 Deaths. And $281 Million dollars in the United States, 100 deaths and $100 million in damage in Canada, and an estimated 400 to 1000 deaths in Haiti.
5. Include at least one picture.

Blog 6 ! =)
1. Which blog was your best this quarter? Why?
I enjoyed doing the blog post number 4 because I took my time looking p the information for the sunflower pollen and I answered the questions correctly.
2. What topic did you enjoy learning about the most (from chapter 17-20)? Why? Include a picture.
I enjoyed learning about wind speed. I liked being able to team up with a partner ( that I actually liked) and build the anemometer.
3. What grade do you deserve for your 3rd Quarter Blogs? (Keep in mind some basic math. If you only did 3 out of 6 of them you cannot earn above a 50%.)
I think do deserve a 100% because I took my time and revised each blog post and made sure they were done accurately.

1. Check out Fayetteville's pollen forecast. Which is affecting us the most right now: tree, grass, or weed pollen? Specifically, which trees, grasses, or weeds?
Oak Tree Pollen is affecting us most in Fayetteville.
2. "You're Surrounded by Pollen," so read this article. What is needed for a "perfect storm" of pollen?
Long winter pushed back growing seasons for some plants and trees, causing them to bloom simultaneously instead of at various intervals with dry, windy weather, and you have a perfect storm of pollen.
3. Choose a microscopic image of pollen. Which one looks the best to you? Why? Where is this pollen commonly found? Write a paragraph in your own words explaining this specific type of pollen. Include a cool-looking picture. You may need to use other websites to help you.

The Sunflower pollen looks best to me because it is huge, and round with like pointy sides. Sunflower pollen is found in North Carolina, Kansas, New Mexico, etc. It orginated in North America and used as a medicine plant in Europe. It was also very popular as a type of food.

1. The five main states of matter are Solids, liquids, gases, plasmas, and Bose-Einstein.
2. Energy is needed to change gas into plasma.
3. The temperatures are 0. (Kelvin) , -273.15 ( Degree Celsius), and -459.67 ( Degree Farenheit)
4. The temperature in space is 3(Kelvin).
5. What do you think plasma would like look/smell/feel/taste? How about Bose-Einstein Condensates? Do some research on other sites, but ultimately come up with your own unique answer :) I think plasma would look like gas , they probably would not have a smell, it would be way too hot to touch, and it would also be very dangerous to eat/taste it. I think Bose-Einstein Condensates would look like a cold solid ice cube, it probably would not have any type of distinct smell, and would maybe be cold enough to give you frost bite, and it also would be wat too cold to touch. OUCH ! !
