Is There Life in Space? | 5/20/19-5/24/19


       There is life in space. This is because their is so many stars and planets in the universe that it is unimaginable to picture. It is in fact so big that we had to create new forms of measurement to measure things in space. Even one of those measurements is still so big to us as just one light second is the equivalent of going around Earth's equator 7.5 times. There is at least one hundred billion galaxies in the universe. This means that at least one of those galaxies should have one star and one planet that can support life. That one of the galaxies in the incredibly large universe must have one planet that has life currently on it.

       Currently their is two major methods for discovering planets, the transit method and Doppler Technique. Along with the use of technology such as the Kepler telescope, we have quadrupled the amount of planets we have detected in six years. By that rate, or a similar rate, I think that we must be able to find at least on planet that is habitable. In addition, technologies like the Kepler telescope have made it much easier to detect planets due to how they are more precise than the technologies that we used when first discovering planets. For example, having the Kepler telescope made it so the data received had less noise due to how it was above Earth's atmosphere. On top of this, scientists already know what type of planets to look for. Planets that are rocky, middle sized or very big, and have an orbit completely in the liquid water zone of its star. Hence, it should be much easier to find habitable planets if scientist already what to look for. Lastly, scientists can also use spectra to understand the atmospheres of planets to determine if they are habitable. These spectra tell scientists what type of elements are in a planet's atmosphere so that we know if they can support life.

       Space is vast and large and their must be at least one planet out there that is habitable for life. Scientists have found so many techniques to discover planets that involve using the transit method, Doppler Technique, spectra, and new technologies such as the Kepler telescope. Scientists also know the certain characteristics a habitable planet should have. In combination with all of these things, scientists surely will be able to find at least one habitable planet that has already existent life on it.

Systems In a Human Body Info Paper 10/15/15

Image
Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed ...

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

Plate Tectonics 3/10/18

Image
Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges...
