1. What are 3 scientific facts that you learned from watching Journey to the Center of the Earth?
-Magnesium is flammable.
-Muscovite is breakable.
-With enough water magma can have a geyser reaction.
2. What are 3 things in the movie that were scientifically untrue?
-Birds can not glow.
-The center of the earth would kill you instantly, because it's nothing but magma.

1. What was your favorite topic that we learned about this year in Earth Science?My favorite topic that i learned about is the astronomy.
2. Explain this topic. Provide a picture and/or website link to better illustrate what you learned.
Astronomy is about space and whats in it. Like the stars, planets, moons, galaxies, and the black holes.

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?
This is cool because it is cool knowing there is a lot of stuff that we need to k now about .I like this topic, because i love to look up at the stars and knowing what else is up there

What do you think the universe looked like before the Big Bang? What made the universe "bang?"
I think the universe looked like a huge star. Space itself made the universe "bang".

1. What are the four ways astronomers can detect extrasolar planets?
Radial Velcoity, Astrometry, Opitcal Detection, and Transit Method
2. Choose one of the four ways and explain it in detail.
Radial Velcoity is also known as Doppler spectroscopy, this method measures slight position of a star that happen as it is tugged to and fro by a planets gravitational pull
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.
They have not given a answer but a vast amount

Which planet or moon is your favorite? Why? Please include a picture.
My favorite planet is one of saturn's moon, Titan. I like Titan because its the secong largest moon in the solar system, and because its the only one out of three that have an atmosphere.

Black holes emit x-ray radiation and get smaller and smaller until they disappear, or "evaporate". Most black holes form from the death of a large star that are much larger than the sun, that run out of fuel and cannot sustain its nuclear reaction. The gravity around the "hole" of a black hole is so strong that NOTHING can make its way back out after a critical distance. Even before crossing the event horizon, though possible to travel away from the black hole, it is not easy. But even light has a hard time getting out, so light being emitted from something almost at the Event Horizon but not yet inside the threshold takes a much longer time to escape and be seen by someone then it would in normal space going at 186,000 miles per second.
Titan (one of Saturn's moons) was discovered on march 25, 1655, by a man named Christiaan Huygens. Titan is the largest moon of Saturn, and the only one to have a dense atmosphere, and the only moon that has clear evidence of stable water systems. Titan is the twentieth-most distant moon of Saturn and sixth-farthest among those large enough to assume a spheroid shape. The moon is primarily made of water ice and rocky material. Titans atmosphere is largely composed of nitrogen and its climate includes methane and ethane clouds.
Big Bang Theory is an effort to explain how the beginning of the universe was created. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity.
Milky Way Galaxy is the galaxy which is the home of our Solar System together with at least 200 billion other stars (more recent estimates have given numbers around 400 billion) and their planets, and thousands of clusters and nebulae, including at least almost all objects of Messier's catalog which are not galaxies on their own (one might consider two globular clusters as possible exceptions, as probably they are just being, or have recently been, incorporated or imported into our Galaxy from dwarf galaxies which are currently in close encounters with the Milky Way: M54 from SegDEG, and possibly M79 from the Canis Major Dwarf). See our Messier Objects in the Milky Way page, where details are given for each object to which part of our Galaxy it is related. All the objects in the Milky Way Galaxy orbit their common center of mass, called the Galactic Center
Binary Star Systems are quite common. In fact, most stars are in binary or multiple star systems. If the orbital plane of a binary star is seen by us nearly edge-on, the stars will alternately eclipse each other. These binary stars are so far away from us that they look like single stars in photographs, but their brightness varies in a particular way due to the eclipses - these are known as eclipsing binary stars. About 6,000 stars of this type are known in our Galaxy and other nearby galaxies.

In your opinion, is Pluto a Planet? Why or why not?I think that pluto is a planet , because its in our solar system so it's got to be a planet. If it wasn't a planet then why is it in our solar system.
