Journey to the Center of the Earth

1.) I learned that when you have a lot of lava and a lot of water, it creates evaporation.
I know that in mines there are sometimes diamonds, emeralds, and rubies.
Magnesium is extremely flammable.
2.) The blue electric bird is not a real bird.
Dinosaurs was never alive with humankind.
There is not a center of the Earth.

My Favorite Topic

1.) My favorite topic we learned this year was Index Fossils. 2.)An Index Fossil is a fossil that can be used to give the age of a rock. It includes: Radio-activity, half-life, Radiometric dating, Radiocarbon dating, and more. 3.)Ha-ha funny Mr. Dunn, but I like this topic because it had a little math in it. I love math and anything that deals with math, I most likely like! Another reason is because I think it is amazing how scientist can figure out so much from a fossil just by knowing where it came from and etc.

Big Bang Theory

I think the universe looked liked a, Big Piece of Nothing! I think it was black and boring. There was nothing interesting at all about it so, there is nothing I can really say about it. I think the big "bang" is when the world began to revolve and form bigger and better things. Now that I think about it, I think that the big "bang" are the planets! The planets are the "big talk" about the universe, I think. Scientists are always wondering if there are people on this planet or how much oxygen is on that planet! Therefore, I think the big "bang" is the planets.

Extrasolar Planets

1.) The four ways astronauts can detect extrasolar planets are: Radical Velocity, Astrometry, Transmit Method, and Optical Detection. 2.) I'm going to chose Radical Velocity, it measures slight changes in the position of a star that is tugged towards and away from a planet's gravitational pull. The changes can be detected by measuring the Doppler Effect. When light from a star is moving away from the observer is shifted to the red end of the spectrum, and when the light from a star is moving towards it, it is shifted to the blue end of the spectrum. By measuring the movements of the spectral lines over a period of time, the orbital period of a planet can be determined. 3.)Google says it has detected gas giant planets thought to resemble, Jupiter.
